UTG PRO 15 Drop-in handguard

Excellent product and very easy to put on my AR15 I painted the handguard camouflage green to match the color of my rifle.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Ruger AR 5.56

It's a quality built carbine length rail, but if you have the bayonet lugnut you will have to slowly grind the sides down with a dremel and with careful and precise craftiness i was able to get it to fit perfectly with little to no scratches as shown in the pictures..finding an extended rail was hard to come across so I took the chance and bought this one..the bayonet lug for the ruger AR 5.56 isn't standard so most extened rails will not fit perfectly..if you been researching handguards for this gun, and DONT want to cut the bayonet lug off, buy this one and do a little craftsmanship. You could cover the aluminum scrape marks with a dab of black paint or use a sharpie until you find what best works for you..

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Thanks for sharing your feedback, Timothy. We're glad you're satisfied with your purchase. Cheers!

Completely Worth The Money

I have been looking for a full length handguard for my AR w/front sight post on and off for quite some time. I even contemplated buying a completely new upper with a low profile gas block to achieve this. That is, until I came across this product. This was totally worth the money, and obviously a lot cheaper than buying a quality new upper. It was a breeze to install, with no modifications necessary for installation on my Bushmaster carbine, taking about 5 minutes.

If you are looking for an quick and easy new look for your AR w/front sight post, this is definitely a great way to go.

First photo is with Magpul carbine length hand guard. 2 and 3 are with new UTG Pro full length hand guard installed.

Thanks for sharing your feedback, Brian. We're glad you're satisfied with your purchase. Cheers!

Excellent product but READ SPECS before you buy.

First, It's an EXCELLENT product! Lightweight, durable, and MADE IN THE USA! It looks fantastic and the drop-in design is genius.

I purchased this handguard for my Ruger AR-556 because I wanted to keep my factory sights. Turns out that the Ruger AR-556 does not have the common, 'standard' front sight piece and the front-bottom section of this guard does NOT fit around the sight assembly. After some slight craftiness with a Dremel tool and certainly voiding my warranty, I was able to get it to fit. Pics included.

As you can see, it's some rough grinding and could certainly look cleaner, done by someone better than I.

Looking good! Thanks for sharing, Jonathan. We're glad you're satisfied with your purchase. Cheers! - AB
