    Good to hear.
    Try some CCI Mini Mags.

    Naw those rounds are way too expensive- if they sold them in bulk yea but they never have! Used to use them when they first come out now they are like $6 for 100!!

    I use Federal #750 bulk pack from Wally World. They cost me $16 for 550 and works great in my kit.

    I definetly agree. I'm not shooting Mini Mags just to plink. They do provide better accuracy but the Fed bulk and Winchester bulk from Walmart is what I shoot for "shooting"

    22 Conversion with 1/7 twist

    Hi, this is my first CMMG and it has 1/7 twist. No problems thus far. I read something about the 22lr not being suited for a 1/7 twist. Any truth to that?

    Not suited in respect of accuracy. 1/7 is on the low end for accuracy with a .22. 1/16 twist is the proper twist.
    Different barrels and ammo combo's will produce different results. Ball park for a 1/7 with .22 is about 1.5" to 2" at 25 yards.
    60 gr. Aguila should work well.

    CMMG kit without problems

    Perhaps I got a good one, I got about 500 rounds thru the conversion kit (non- stainless) using Winchester 36 gr HP, some old Hanson 40 gr solid point, some Federal 37 HP. Just 1 failure to fire, otherwise not a bobble. The kit has slid in and out without trouble (just 2x) to take a look and wipe down w/ SLIP EWL. A previous post made me pay particular attention to the inside of the upper receiver, no damage, no scratches inside. Got mine from Brownells on sale $189 or $199 I recall w/ 3 25 rnd. smoke mags. Set into a carbine parts kit I put together about 16 years ago w/ a 1/7 bbl. Big fun for less than $200, I feel lots better about running some drills for less than .75 a mag

    I bought the Atchisson AR15K10 kit today at Cheaper than Dirt along with a 333 brick of Winchester in McKinney, Tx for 130 bucks I think it was. Bought a Black Dog magazine to go with it but found out later that its not the correct magazine. I figured out alittle while ago that its for the Olympic Arms kit. Exchanging it tomorrow.
    Anyway. I took it from the store to the range. Installed it in my 6920LE, cycled it about fifteen times, loaded a magazine and off I went. 333 rounds later, with a dry bolt kit fresh from the box, I had five failures. Im reasonably impressed. Accuracy off hand was better than expected, even the RO commented on it. He uses the same kit.
    I got back to the "Fortress of Solitude" and cleaned it, fluffed it up some, now its even smoother.
    Im going to switch out the BD magazine for the correct one and hit the range next weekend as well. Loving it.
