    I am a big believer in hunting with work guns, so am wondering about use of the conversion kits for hunting small game.

    I keep hearing accuracy is less than stellar because .22 LR is a bit skinny for a 5.56mm bbl. Not wanting "match" accuracy but it would be nice to be able to headshoot a squirrel inside 30-40 yards.

    So (and maybe this is best posted in ammo section), has anyone tried running their conversion ammo through a sizing die that bumps LR up to .224? If so, did it improve accuracy in an AR barrel any flavor and twist?

    Well, yeah! It doesn't have holes in the chamber adapter!

    If any need some help with your CMMG, Ciener, Spikes 22lr kits and using
    Standard vel and Subsonic ammo here is some tuning tips.
    http://home.netcom.com/~uzisubgun/id3.html
    .
    These kit are made for Hi Vel ammo but after some fine tuning they run great
    with most any ammo you feed em.
    I have 3 Cieners, 2 CMMG, 2 TacSols and 2 Spikes kits and all run Great
    after fine tuning.
    To make loading those BlackDog mags easy, take the mag apart and use
    600 grit wet/dry sandpaper on the grooves that the follower rides in until
    smooth.
    If you run your finger nail down the grooves you will feel little bumps,
    and when removed the mags loads and feeds better.
    If you would like to use a lube to realy improve loading use Dryphite not a
    wet lube or the mag will collect alot of blowback crap.

    Christmas Delayed is OK by me!

    Computer was done for a couple days so I finally got back on after doing an unsuccessful deer hunt this morning. Checked my SO email address to see progress on delivery of my CMMG unit and running the tracking no. showed it had been delivered to my front porch while I was in a tree stand!

    Yep, it was there.

    The chamber insert appears flawless and I'm going to have to head back up the the farm to get some trigger time this afternoon.

    The Brownell's instructions state no subsonic or hyper-velocity, but I've got to see what the Aguila SSS do just for kicks.

    You got it already, good! We need to know 2 things - how long from order to delivery, and how does it shoot?

    Ordered 12/23. Received 12/29.

    The day I ordered Brownells had 200 of the CMMG + 10-round Black Dog kits. They had the 27-rounder mags available separately.

    Don't know how it shoots yet cuz I got stuck going grocery shopping with the commandant of Stalag 1369!

    Did lube the rails well with 10-8 Performance Lube so have high hopes for the morrow.

    As stated, the kit came with a 10-rounder and I ordered two 27-rounders. Will probably try to pick up a couplefew more next paycheck.

    Stole a minute while at Wally World and found out the Fed 550 Bulk Packs were out! Dude said they won't get re-upped till after New Year's.

    They had the Fed 510 AutoMatch load @ $14.35 for 375 rounds, but I am loathe to stray from my favorite .22 ammo.

    .
    That 10 rnd mag can be changed to a 27 rnd easy, take the mag apart and
    remove the 2 plastic pegs that stop the follower.

    Yes, only diference is the round plastic stubs inside the mag that need
    to be filed or dremel out.
