5.0 Rating Great Gas Block - 10/15/2012
Reviewer: Old Sgm
I got this gas block to replace one that did not work. This one fit snugly, bolted on easily, and turned a hit or miss gun into a flawless shooter. It is better looking, too.

5.0 Rating Couldn't ask for better!!! - 11/5/2013
Reviewer: mcorder
Didn't know what to expect but was pleased in everyway. My life depends on the parts on my gun. Not a time to find out they are sub-standard when you are drawing down on someone. Would recommend to anyone who puts their life on the line every night.

4.0 Rating Good but too short - 11/14/2013
Reviewer: Big Matty
Great quality item for the right price. Make sure you measure your rail height before you order. I received the gas block, and it fit great. Nice and snug and a simple install. Only problem is it's about a quarter inch lower than the rest of my rail system. If the height were right or I had measured first I would have known better. Still I would recommend this G/B for its simplicity and ease of install.

5.0 Rating Solid fit. - 10/31/2014
Reviewer: Edward Guzman
I ordered this to go on a 6.8 SPC build. Anyways, it works very well and sits clean on the barrel. The height of the rail is a bit lower than the rails on the hand guards. I've had problems with other gas blocks not keeping pressure and it'd prevent proper cycling. In general, it's a good gas block and the price is nice. I'm going to order another to put on a .300 build next. I'd recommend this to anyone.
