FREQUENTLY ASKED QUESTIONS
Q: How do I know if this will fit my AR-15?
A: This will fit any AR-15 that has a standard mil spec upper receiver. It will require some modification to your firearm though, including replacing the barrel nut, removing the flash hider, and possibly adding a low profile gas block. Want to learn more? Watch the installation videos.
Q: Do I need to buy anything else?
A: For longer handguards you may need to replace the gas block or front sight with a low profile gas block, available here. These gas blocks are low enough to sit under the quad rail. (Since this is a 7" handguard, you should be able to skip this step).
You will also need to get an armorer's wrench for the barrel nut, and we highly recommend a vise block to hold the upper receiver in place while you work on the weapon. Get armorer's tools here.
Q: Will this work with my AR-10/.308?
A: No - these quad rails are made for standard AR-15's. If you have a 7.62/.308 AR variant, check our our AR-10 / 7.62 / .308 page.

Solidly built ! I am waiting on a billet upper and a F-1 barrel to start my build. Seems like it will go together fine. Would have liked the front end cap available with the rail, but was able to order it seperately. No big deal.
I like what I see so far! As soon as the rest of my parts arrive I will see how well it works.
I am happy to wrote this as your product is if quality material and looks great. Thank you
order arrived quickly, install was easy. If I had to say ANYTHING negative about the install it's that the barrel nut holes, that the gas tube passes through were slightly misaligned. I had to carefully tap the gas block until the gas tube fed into the upper receiver. Once it was in the BCG and gas tube didn't line up correctly and the bolt would fail to extract because it was binding on the gas tube. Once I bent the gas tube a little everything lined up the way it should. Fit and finish of the rails are superb!! I will buy rails from AT3 again and again!
great customer service
Everything is great. Had one small problem getting the set screw to tighten and hold the rail in on center. had to grind a little off the side of the hole in the barrel nut. work great now.
Looks great, fits great, and functions great. No complaints here.
I just happened to stumble upon AT3 while googling forends, was semi-skeptical thinking i'd get what i pay for but I figured it was worth a shot (pun intended :) ...) The shipping was amazingly fast and the product was bagged, then bubble wrapped, then boxed - needless to say i was excited to tear through it all and see what if actually looked like on the rifle. It is flawlessly finished, any and all sharp edges have been smoothed out and it threaded on without a single hickup. To say I'm very happy would be an understatement. I'll be ordering these for all of my builds from now on
Very pleased with the overall quality. Bought the 12 inch quad rail to mount bipod, scope and front pop up sights. Everything fits and weight is bearable.
Fit and finish is top notch. Very good quality and fits like a glove. Would buy again for next build.
exactly as advertised, good pricing and fast shipping.
I just purchased this quad rail for my first top to bottom AR build and for the price it exceeds expectations. There are some problems I have that if the rail cost what other competitors do I would have a problem with. The barrel nut is a bit week and my wrench stretched one of the holes that had to be smoothed back out, and the rail run just slightly at an incline from the receiver to the end of the barrel. I measured the gap from the top of the rail to the barrel at 16 mm, and the gap from barrel to bottom of the rail at 14.5 mm. So probably insignificant but definitely there. This still gets five stars though, the rail is sturdy everything came together very easily, the shipping was incredibly fast. So overall I am very satisfied.
Good quality product, customer service was top notch and I rate that at five starts. The handguard is lightweight well made and good quality. I didnt rate it five stars because the barrel nut seems to be a little soft when i was torqueing thebnut down I daw the hole deform slightly.
Fast shipping and good quality.
Great quality and super fast shipping. Will buy again on my next build!!!!!
I recently purchased the free float rail haven't had a chance to mount it but it's a nice rail feels real solid I can't wait to get it put on
My rifle is a optics ready. Removed hand guard & gas block. Ground bottom of gas block. Everything else went on perfect.
They look great, but the barrel nut deformed because the holes did not match up to either of the three wrenches I have. Ithey were close, but I had to tap them in and that made the exterior of the nut bulge out enough to where I could not get the handguard on. I had to use a punch to tap the areas down so I could get the handguards on. I got them on and love them. If you wanted to send me two new barrel nuts. That would be great. One last thing, the other side of both barrel nuts fit all three of my wrenches perfect.
Very lightweight and durable. Good quality construction and the same of which you find on other big name brands.
Out of the box the guard has a good finish. The installation was straight forward, the gas tube lined up easily within the tongue spec. Once installed the guard feels rock solid, I have only put about 120 rounds through it at an indoor range but with the installation and solid feel I don't have reason to believe there will be problems in the field.
This hand rail is quality made and looks awesome very pleased ,Excellent finish and design.My next build will have the same hand rail.It comes in several lengths. Highly Recommend It
Five star on the hand guard. Four stars on the barrel nut. Both barrel nuts I purchased disfigured when I torqued them down. The wrench didn't fit in all the way and when I tapped them in (gently), it disfigured the exterior of the nut. When I tried putting on the handguard, the handguard threads got messed up by the disfigured parts of the barrel nut. It took using some punch pins to tap the disfigurements down, but after that, everything went on fine and made my gun look sexy.
Exactly what I wanted for a reasonable price
Can't beat the price for a well made quad rail.
Great product. Looks well made. Good value
delivered on time, product is good.
I have only been to the range once with it so far so I cannot speak to the durability of this rail. The price is hard to beat. But, the tolerances were off on the barrel nut gas tube openings so the pins of an armorers wrench did not fit. I made a slight modification to make it work.
The AT3 12 handguard is everything AT3 claims it is; strong, tough, plenty of rail estate. BUT...when installed according to the video, the top rail is clocked to the left of the firearm 0.045 inches, and the whole tube runs 'uphill' about 0.015-0.020 inches. The rail is fitted to a Northwest Custom Precision upper, with a Daniel Defense Barrel and Spikes Tactical BCG. I had hoped for a better fit - but, the rail will carry a bipod well, and that's all I really expect it to do. Customer service and shipping were great, guys.
The product is great quality and the service is top notch. Definitely will purchase from this company again in the future.
I recently received my second one of these rails and you still can't beat it for the money. The first one I ordered came in quick and was flawless. The second one also came in very quick but the finish was chipped it a few places. Still can't beat it for the money.
Just received the rail and super impressed on how it looks. Awesome black finish with no marks or blemishes. Cant wait to put it on my rifle. Amazing customer service as well.
Looks flawless, haven't mounted on my gun (waiting on parts) but barrel nut and all with the set up. Would recommend until proven differently. But this looks grade A and the price you cannot beat.
Feels good and sturdy, holes for gas tube don't line up exactly right, they sit a little low so a good amount of force has to be used to get tube to slide back in. Also be careful when tightening retaining bolt, on bottom rail, if you over tighten it can start to pull the rail away from the ring. I will re post once i have run it through the woods and multipul firing situations.
Happy with the overall quality of the rail, my one gripe is the diameter of the rail itself. I would have preferred to get the slim design of the "pro series" but I wanted the continuous top rail where there is a gap with the "pro series". Everything considered, you cant beat the price and service, with fast and insured shipping.
Just got it installed today, great quality budget free float for the money and with the right tools a simple install would recomend to anyone on a budget and looking for a freefloat rail
Great, fantastic, awesome, I was a little cautious due to the cheap price, but this is a high quality quad handguard rail. Installed on a DPMS, it looks great. With the end cap it gives that finished look. The rails are milled to the correct tolerances per Mil-STD-1913 allowing all of my accessories to fit perfect. Used the Wheeler Upper Receiver Vise Block Clamp to hold the upper while I torqued the barrel nut (30 - 80 lbs) went to 50 lbs to get the gas tube aligned. I must mention the (2) day fast shipping. hope I didn't double up on my REVIEW, I don't think the 1st one I wrote took.
Installed on a DPMS with no problems fit excellent. Most importance to me the Mil-Spec 1913 rail are to spec and all of my accessories fit perfect and snug. The price drew me in, but don't let the scare you these are excellent quality and look great. Shipping was fast (2 days). I also went with the end cap, highly recommend it for a finished look.
This T-series rail's barrel nut threaded on and locked up great at 45lbs. The rails top lined up with with the receivers rail and leveled great. The front cap I ordered fit fine to round things out. It has the fit, look and quality of rails costing much more; I will be back. Art
The rail is a bit heavy but cost 1/3 of the other rails in its class. It's only a matter of time until the firearms community as a whole discovers AT3 Tactical and their product is harder to get and more expensive. Enjoy this hidden gem of a company while it's a secret!
Pretty good price for this type of shroud. During installation, the barrel nut broke while trying to torque. One of the holes where the barrel nut tool hooks into broke out/exploded. Had to file it down to get the shroud to thread on. After installation, I noticed at the barrel end there is more of a gap on the top of the barrel than at the bottom.
Excellent product, well made in the USA and you get a good amount of bang for your buck!
awsome service good products. just wish at3 carried more product, like ammo and barrels etc . will reccomend
If I will build another rifle , definitely I will buy another one of this hand guard. Good quality and very reasonable price compare with other products out there. I'm really very satisfied, thanks.
this is without a doubt the best bang for the buck out there. it is exactly what i was hoping for, no surprises, no b.s. this is a good rail. the only reason i didn't give it 5 stars was because the threads inside the barrel nut were a bit rough. not bad enough to cause any problems, but they were not to the same quality as the rest on the rail. if you are thinking about getting one of these, just do it! you will not be sorry.
I am hoping that I just received a bad example of this product, maybe it was made on a Monday. When I was installing it, everything looked great, had the rail lined up, cinched down the jam nut, but then, when I went to torque down the anti rotational set screw, I went finger tight, the a quarter turn, but before I got to the quarter turn, I heard a "CRACK" well, that sound was the back of the lower rail coming off of the thing. It is still on the rifle securely, even though it was broken. I am hoping AT3 will help me out, this is the first time me, or my friend who was there when this happened, have experienced anything outside of excellence from an AT3 product.
well built, inexpensive and light weight addition to my ar. I had the old one off, along with the barrel nut, gas tube and gas block, and the new one installed in about a forty five minutes (I'm kind of green when it comes to gunsmithing) and everything went back together as it should. Had a little trouble getting the existing top rail on the rifle and the one on the forearm to line up while tightening the castle nut, but a little patience and it was good. Thanks at3tactical!!
The ordering experience from the website was pleasing. The quad rail I received is exactly what was pictured on the site. The rail is a bit lighter than I had expected from a quad rail, which with my polymer lower, is rather pleasing. It appears to be plenty sturdy. I don't have the weapon built yet, so I can't yet comment on the function, but it definitely looks the part of other high end rails, but at a much more affordable price.
I ordered this rail as a place holder so that I could shoot While I saved for a different rail. I received the rail in two days and am very impressed. Solid fit. I haven't thrown it from a helicopter but it seems pretty tough. I had a few installation issues but the outstanding customer service went way above and beyond to resolve them. I am very pleased.
Pros: Low price, great shipping, great look, all inclusive parts (- tools.)
Cons: No directions included with packaging, tolerances off by -/+ 1/32" (caused slight problem when mounting Magpul PTS XTM rail covers.)
OVERALL: Based on what you pay, this is a hands-down great bargain! Although Cons are listed, work arounds are readily available (i.e. youtube installation videos, and using chisel to remove about 1/32" excess material from rail guards to allow fit.) The only reason I took a star is because I had to modify a different component due to tolerance flaw.
Awesome product for an awesome price. I will be a repeat customer.
Shipment was fast, product was of high quality and customer service was great!
Thanks again for offering great products at a fair price.
I bought 3 of these for a few sbr builds. I have to say I was surprised by how good they were for the price. Also the shipping was very fast and they were well packaged. Overall great transaction ,thanks!
