CMMG 22LR Conversion problem??

You see the bullets have to fit tightly so the rifling in your barrel can cut into them and cause the bullet to spin. This stabilizes the bullet while it’s in flight. Do you even know what a gun is? You should probably only use nerf guns, it would be safer for the rest of us,

well I know very little about rifles but that's a 223 chamber insert and the 22lr goes in the other way hence case staying in insert chamber leaf going through hope into barrell or possibly u taking the piss and u know this

Dude you have no business owning a firearm!!!!

A TIGHT BORE IS A GOOD THING…That is a proper fit and as designed… >>>An excessively sloppy or slip through fit of bullet through "barrel" may lead to gas blow by and gas cutting of the lead bullet…. i.e. undersized bullets or sloppy/over-sized bore will allow more leading {lead deposits in barrel due to hot blow by gas cutting away or melting bullet sides} As you can imagine with under-sized bullets or over-sized bore, accuracy will suffer… .224" to .225" diameter lead bullets should give best results in your conversion… Foreign {Not made in USA} brands are more likely to have the over-sized dimensions you might prefer… I SUGGEST you measure bullets to confirm….while hoping to find .224" to.225" rimfire bullet diameters.
IN USA: Typical rimfire dimensions are .220" … Elsewhere in the world: .222", .223", .224", and even .225" are found.

Please take all his firearms away from him before he hurts someone!

And you own a gun, people stand back when he goes to the range

well this isnt really video worthy but dude shouldnt be a problem

I have three CMMG kits. I use Black Dog and CMMG mags. Check to see how loose the mags fit up in your rifle/pistol. If there is any 'wobble', place a small strip of sticky sided velcro on the front of the mag where it protrudes out of the mag well, so the wobble stops. You will no longer have drop free mags, but your tool will function so much more reliably! Try it, it works like magic.

do the same thing to any gun barrel with the correct caliber, you will get the same results.

That is normal. That protrusion on the end of the bolt that exactly mimics the 223 shell casing is effectively an extension of the barrel with this system. If you load a 22 lr round into the CMMG bolt while out of your AR, you see that there is alot of space between the end of that bullet and the beginning of the barrel on your AR. The bullet would not fire properly without immediate resistance on the bullet, as much of the gas would push past it before it hit the barrel, and the bullet itself would be tumbling somewhat before it hit the barrel (neither of which is good). So yes, that is normal functionality for that unit. Go enjoy it.
