Utg pro Arwen m-lok handguard

Very nice handguard, measurements are actually 4.75 with 1/4” tabs, which they said 5”. It was a little to short for me, but it’s a nice handguard.

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

Solid, attractive handguard on a budget

I chose this handguard for equipping a new lightweight rifle build which had a 14.5" Faxon Gunner barrel with an integrated flash-hider. Due to the length of the rifled portion of the barrel, I needed a 13 or 14-inch handguard to get as close to the muzzle device segment as possible without overlap, as a standard 15" handguard would not do. Very few companies make a 14" MLOK handguard, so this was perfect! It has excellent T-marks, a perfect shade of anodizing that matches the Aero Precision slick-side upper I mated it with, and anti-rotation tabs that will work with most billet uppers as well as forged. Many handguards are incompatible with billet uppers if they have such tabs, as they interfere with the upper in some way. The only reason I deducted one star was for lack of integrated QD sling interface studs, which by now should be standard on all free-float handguards. Since the Arwen is new design, I would have expected that feature given the price point. It does, however, have a few extra MLOK slots at on the flats near the muzzle end, instead of at just 3, 6, and 9 o'clock positions like most. That is quite useful for mounting offset lights, lasers, etc. without the need for a separate offset mount. Overall, a well-made, fairly lightweight but solid handguard that gives an impressive look to your upper.

UTG Pro Arwen M-Lok Handguard

Simple sleek rail. Looks great. Time will if the locking system will hold up. I run my rifles pretty hard. It old use one or two more locking screws. But the two currently on it should work for most.
