  1. What Can One Say, It's A Gas Block...

    Posted by dbledsoe@isp.com on 30th Mar 2016

    not a lot of magic in a gas block. The Apex is very well machined and coated. Seems to fit adequately, and is certainly handsome for a low-pro gas block.

    The one thing I wish makers of AR gas blocks would address is if they require a spacer. The milspec placement of the gas block is .xx" ahead of the barrel step machined into the barrel to place/position it. That barrel step stop for the gas block in milspec barrels is machined into the barrel to include a distance for the forward hand guard cap. When building a rifle or carbine using a free floating hand guard tube the gas block should not be butted up against the machined barrel stop. It needs to be spaced forward .xx" to properly mate to the barrel gas hole. Few, if any, tell us that.

  2. High quaity and design

    This block is well made and finished. Block fits right with all the clears for extended rails. Good stuff!

  3. Perfect - Exactly as Described!
