Billt... you will put a bunch of residue into the action if you use a chamber insert on an AR with a standard gas tube.. when I used my CMMG A unit for 3 gun practice, I put 1000 rounds of transition practice prior to the 2009 Ft Benning match, by 2010 I had cobbled a spare upper to which I had removed the gas tube, and closed off the gas port with a stainless screw clamp... plenty accurate for what I was using it for... after 2010, I got a 16" dedicated barrel... when I got my registered SBR I got the 10" and short 9mm options also.. regards

my first decision was to build a 10/22 for Steel Challenge... I just was unhappy with the reliability of the platform (mine was not a Ruger receiver)... the short AR works fine for me... I have a 16" backup

Rastus... some of the bulk ammo now available is marginal in operating the action of my Ruger MKIV lite...some failed to sufficiently move the bolt to re-cock the hammer... I added the Volquartsen adjustable spring system, using the lightest spring, to help alleviate the issue... still had a couple fail to extract, but not with the CCI Blazer I use for competition ...the CMMG unit in the rifle has a longer spring travel, and I think this helps with reliability... regards

It came this morning. I didn't care for the blister pack they shipped it in, so I went to Harbor Freight and picked up one of those Apache Pelican style medium sized cases with the "pluckable" foam, and it fit perfectly with all 3 magazines. As soon as it cools off, I'll take it out and light it up. It looks to be very well made. We'll see.

Nice.  Let us know how you like it.
Necessity is the plea for every infringement of human freedom.
It is the argument of tyrants; it is the creed of slaves.
