Great fit and finish
by Chris B
I've used this before and at this price point I'll use it again.

well built and very low profile to fit under the V-RS "T" hand guard
Pretty solid, looks good. As a lot of AR components I've received in the mail, it had a few little finish issues and blemishesâ€¦ Nothing a little bluing couldn't fix.
Good gas block
Does what it's supposed to under a BCM Alpha 13" handguard. Finish was solid.
Low-pro free float is the way to go.

I didn't purchase this at $33.25 (I got it on sale) but I'm very happy with the part and it does the job exactly as advertised. The screws for install have small teeth so they bite into the metal inside the dimples you'll be drilling in your barrel. It's a very easy install that can be done by anyone who has basic knowledge of handheld tools. Multiple instructional videos on the internet can walk you through the process easily.
