Great product - Guntec USA 4in Ultra Lightweight Thin M-LOK System Handguard w/ Monolithic Top Rail

I bought this handrail because it was cheap but I'm very impressed with it. Clean and good looking, very easy to install. The barrel nut is steel instead of aluminum like many rails are, and it doesn't require a special barrel tool. Also it came with the barrel extension shims, which most don't. It's the only handrail I haven't had any trouble with( including: juggernaut tactical, Midwest industries, and black rain ordinance). Honestly it's a good product at any price and a great deal at its price. I will be buying more. It is quite skinny though, as in overall outside diameter, which I like but some may not.
