    CMMG 20" .22LR Range Report

    I finally got to the range with my 20" .22 LR and the new CMMG Mags.
    I started with the 25 round mag. Started off fine. Easy to load, fed reliably. Then I started having FTE's which I never have with a CMMG set up.
    Turns out it is the BHOA. I was told by CMMG that the BHOA will require a 45 degree angle ground on the forward part of the tongue(metal tab that the follower pushes up on) It also needs to be slightly shorter for use with the new mags. I tried to do it with a Dremel but the hardened steel wouldn't budge.
    CMMG will offer a free exchange on the BHOA and offer a "How To" for guys that want to do it themselves. What happens is the tab hits the rim of the round and get jammed up.

    For the range results.
    I took the wron lower with me. I had a new, bone stock CMMG lower. G.I. trigger which isn't great for groups.
    I tried CCI HP
    CCI Subs
    Federal Bulk
    Winchester 333 Bulk

    My little friend, oddly enough, likes the Winchester 333/555 Bulk sold a Walmart Yeah me!
    Rifle was consistant, especially considering the trigger and shooting bulk pack.

    Rifle has a Mueller 8.5-25 Tactical Scope with AO
    TacSol .22 Comp
    Free Float Rifle Tube

    I ran it dry until I had the cycling issues. Pulled the bolt, 1 drop of oil per rail, no more feed problems.

    Here is what I got. All targets at 25 yards. 5 shot groups with Winchester 333 Copper Wash 36gr. Bulk
    Rifle


    Results:




    I shot a few rounds at 50 yards. Someone left a 2x2 Shoot and See. Every round was on it and consistant. Next trip will be at 50 yards with a target lower

    Looks like a fun day at the range. Thanks for the report.

    Thumbs up

    The accuracy you're getting is quite good for an AR15 .22 lr upper IMO. Congrats on a good one.

    I think I can wring more out of it with better ammo. It shot consistanly at 50 yards, so that will be the next trip.
    Eley EPS did best in my M4 LE but had some failure to ignites out of the second box I tried. Could have been a bad box.
