Ordered the 12 inch rail for a pistol build. The barrel nut doesn't require indexing, which is awesome. I love the feel and weight of this thing. Especially for the price. The cons I have are: Mine didn't come with anti-rotation tabs, instead it has two screws on either side of the handguard that screw into a groove on the barrel nut, (which I assume is there to keep the handguard from sliding forward?). When I fully engage these screws with the barrel nut, it leaves a 1/8 - inch gap between the handguard and the upper receiver. Not a problem though, I pulled the screws and got it flush. Hopefully it doesnt move in some unexpected way. All in all, decent handguard for the price.

Bought a 12" inch for a 9MM build. Excellent fit and finish. This handguard is is better quality than ones costing much more. Solid, tight lockup, looks great. Very pleased.

Nice product, fast and free shipping. The handguard fits well and is comfortable to hold. No need to index the barrel nut, just torque to 30 to 80 ft.lbs. The gas tube clears nicely. The barrel nut is 33mm. I would recommend for any build or upgrade.

Bought the 15" m lock . Very satisfied great product, fast shipping not to mention free shipping....great company
Thanks

Extremely happy with this! Ordered the 7” for use with a 4.5” KVP pistol barrel and a 4.5” Kaw Valley Precision Linear Compensator SLIM XL (I have a feeling the XL version, not the SLIM would have been slightly too large in diameter to fit inside of this rail). Fit and finish is perfect! Easy to install, really lightweight and slim. Slides right over the comp and fits like a glove, protrudes a couple of centimeters from the handguard and looks sleek. I was looking at alternatives and was considering the CMMG handguards but I’m so glad I got this instead. While not identical, IMO this one looks better. It’s a steal for $49.99. The best part, shipping was free and the items I ordered arrived in a couple of days.
