  1. What buffers should I use for my CMMG Guard .45 acp with 8" barrel upper?
    I bought the upper to use with the lower thay came with My Banshee 10 mm.
    The
    .45 acp upper did not come with a buffer or recommendations.
    Also I did not receive a manual with my Banshee 10 mm pistol or my .45 acp Guard upper.
    I didn't see a download for these pistols.
    Thank you

  2. I gotta question,i bought the cmmg 300 mk57 upper & got 6 mags in total. If i load 40 rounds into the mag,it will not lock into place,if i drop down to 38 or less it locks in place just fine. Why will it not lock into place with 40 rounds? Is this common? I have it on the spikes punisher complete lower,but still had the same problem when i put the upper on my ruger 556 lower. 38 or less it works fine,39-40 it will not lock into the magwell. It will go in,but will not lock into place.
