- Brand: AT3 Tactical
Gear up with the longest free float quad rail on the market - the AT3 Tactical Pro Series 15.75" Free Float Quad Rail.
LIGHTWEIGHT AND DURABLE
Free float design enhances accuracy by keeping stress off the barrel
Rock-solid 6061 Aircraft Aluminum handguard that withstands the toughest conditions
Rail height perfectly matches an AR-15 flat-top upper receiver - your optics, iron sights, and other accessories will line up perfectly.
Unique low-profile design - taller than it is wide (see pictures for exact dimensions). This makes our rail extremely light and easy to grip.
IMPECCABLE FIT AND FINISH
Precision milled MIL-STD-1913 (picatinny) rails on all 4 rails. None of the sharp edges that you will find on inferior rails.
Vent holes that run alongside the gas tube keep the rail cool, even after a long day at the range.
Hardcoat anodization provides a durable surface that resists scratches and matches your existing parts.

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. 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.

Heavy duty, fits perfect, looks grest. Just stop using USPS. They screwed up delivery date. Please use UPS or Fedex. Dumb delivery people make you look bad.
Ate free float is a awesome product, will look good on my .556
So well made and easy to install. Looks amazing on my 18 barrel. Next ar build gets another At3tactical free float hand guard!!
Amazing got both orders in 3 days also got emails when packages were sent out and delivered. Awesome job thanks guys!
Was worried 15.7 inches would look a little off on a 16.1 barrel, but it's great. Smooth edges, not sharp like some hand guards I've seen. Exactly as described for a very reasonable price. Definitely recommend it
I was worried about it being too long on my 16" barrel AR but it fit exactly like I wanted it. Rail ends at the end of the barrel and only the muzzle brake shows.
I am very impressed with this rail; it's sturdy, well built, and installs very easily. The only thing I wish it had was a connector to make it monolithic but a scope will cover the gap easily.
Such a nice quad rail for the price ........ One of the best on the market !!!!
High quality finish, very solid!
Very well made. Great price. Got the rail/gas block combo package. Very fast shipping!! Definitely will use AT3 again.
After taking me a few days of debating on which length rail to get from AT3 I decided on the 15.75 over the 14.50. The shipping was extremely fast and this rail is even nicer than I thought it would be for the price. Very well made and probably nicer in my opinion than most you find on the Internet.
Fast shipping - sturdy rail - does not butt up to upper rail , but scope fills the void - great price and quality - fast shipping
The forearm was shipped very quickly. It is of good quality. I'm extremely happy with it, just waiting for my barrel to come in to finish my build.
Very easy install , fit & finish is perfect, couldn't be more pleased. First time ordering from AT3, wont't be the last!
Shipped immediately and arrived when promised.5 stars!!
I bought this mainly for the good price but when I received it I realized this was a very good buy all together. Great finish and great feel in the hands. All the sharps edges on the rails have been filed down and rounded off a little. If you are like me and have a .936 OD bull barrel and a .936 ID low profile gas block yes this handguard will fit over it with no issue. Buy this!!!!!!
Everything lines up perfect just not a fan of how it attaches and how the upper rail doesn't fit flush to the upper Reciever. Other than that its a nice rail, should've looked at it better when I ordered.
First of all, this thing is SOLID you can just tell it could take a beating but at the same time it's not overly heavy adding just enough weight to the end to help keep the barrel down just a bit. Also at this price, how can you not?
Seems solid, looks great. Easy to put on. Only other question is durability and that will take time but so far so good. Great product
Great rail. Solid and well built. Fast shipping. Only complaint is there is no way to post pics of builds to show off at products??? Will DEFINITELY be back to buy more!!!!
Purchased 15.75 free float quad rail. Easy to install and looks like different rifle, nice different. Slim and light with good ergonomics. Would buy again.
The inside diameter is not as big as I need. Can I return it?
Fast shipping and an excellent product!! Thank you!!
I've used other rails from other companies that cost much more than your AT3 Pro series rail. But I have to say without a doubt your rail to me is much better in quality and price. I called your shop to inquire about your product and was greeted with very professional and helpful staff who answered any questions I had . I ordered your product right over the phone and the transaction was smooth and shipping was super fast. I will definitely buy from there again and tell all my friends .
Great quality, very well worth it for the price
Awesome fit and finish. Easy install. Perfect length.
Excellent service answered my questions, product looks good haven't installed yet but see no problems. Very helpful, received product in three days. Have already recommended the site to a friend.
Outstanding quality, recommend them to anyone, perfect fit and finish!
Great looking and solid build! Love the way it looks!
Loving the rail. Looks badazz on my AR-15.
Hand guard is well made and was easy to install. Very please with this purchase and delivery was speedy.
Ordered one for my 6.8 build, fit perfect over lo pro gas block, only wish top rail would've met up with the upper instead of having a gap in between, not a big deal, would still buy another one. Can't beat the price and quality with fast shipping. Very easy to install
From the time i purchased the rail till it showed up on my door step it was no longer than 3 days, perfect finish no scratch's or discoloration, outstanding fit and feel on m,y build not to mention the fact i have rails for days.only wish is if we could upload pics
I purchased one of these from an EBAY supplier, last summer. I was very impressed with almost everything about it and have recommended it to several of my friends. There is obviously plenty of space to mount anything you desire and have room for eve more. I wouldn't hesitate to purchase another one from AT3 for future builds.
from what I can tell, this is a great rail.. the issues is it is always out of stock. what can I do to buy one?
Perfect fit and finish.. Super easy to install... Need to let us upload pic's of our builds.. Show off how good these products are...
I would love to send you Guys pix of my final build looks really bad ass
I recommend to anybody
Maybe a bit heavier than other hand guards but well made and a quarter of the cost than the other guys! If your not a gun snob who needs a brand name, save some coin and go with AT3! Invest those savings in a better barrel or more ammo.
I took a shot in the dark ordering this rail. Due to the price I was not expecting much but was pleasantly surprised. Rail on with no problems at all. The only issue I had was keeping it tight but once I invested in a strap wrench I was set. As always, AT3 customer service is great.
Excellent rail system I was looking for a long rail and at 15.75 " this one fit the bill. At a very good price point as well.
Very quick delivery.
Uber sexy appeal to my 300AAC Blackout
Haven't installed yet. Waiting for lower gas block.
Will post pictures later!
Great service. Great product.
Perfect length, looks and feels great! Just wish it had a end cap.
Great product, even better customer service!
The shipping time was amazingly fast first off, but the product was solid and less expensive than the big time brand names. With a little knowledge and the right tools installation was easy! I will definitely be returning for more products!
When I found this rail AT3 were currently out of stock, they kept me up to date with the new batch and I have to say the finish and quality is outstanding. Supper fast shipping and a great company!
Great product, easy installation, fits well, solid as a rock. Super lightning fast shipping and a 1/4 the price of the big names but all the reliability! I will be back!
Spent many hours searching for a long quad rail system for my 20" barrel. The AT3 product looks and fits great and is very reasonably priced. Fast shipping is icing on the cake.
Very well built...solid. Have not installed yet. Ridiculously fast shipping.
I ordered this and had it in 2 days. Rail looks good and covers all of the way to the start of the flash hider. I'm using a counterweight in the butt stock because it's a little nose heavy now.
