Questions & Answers

Will the 9'' rail cover the gas block on a standard 16'' barrel? Featured Answer

Lightweight and looks good by RD, Verified Owner, August 20, 2022
I like this handguard and have several. They are very lightweight, yet strong enough for normal use. Fit and finish are great, looks great on a build. Doesn’t feel quite as strong as some from models (by BCM, Daniel Defense, Midwest Industries, or...
