Practical Solutions' M10/.22 (2nd Edition) Conversion Kit Update

[hacker]

Mine came yesterday and it fit and installed out of the box with no adjustments needed. The first mag ran flawlessly!

On the downside, these mags do not have witness holes or over stop catches. They hold 30 rounds. Don't over insert it past the click or you will damage the feed lips.

When loading the mags, if it binds, it's due to rim lock. Stop and push the top round forward to unlock it. It's good IMO that it prevents that.

Ran a brass rod 10 times in each mag before loading. Ran four mags with 100 rounds and had 3 fail to eject. Next 200 rounds had 2 fail to eject.

The next 200 rounds were flawless. I was running with a Bowers Icon 22 suppressor and Blazer 40 gr. Also ran 100 rounds of Remington golden bullet bucket 36 gr that worked flawlessly.

I am very happy with this kit. Now I can run .22, 9mm, 45 ACP and 5.56 rifle in the M10.

After talking to the folks at PS I think the mag issues are figured out. Just need to test them!

I tweaked the mags a little, feed lips dragging on some of the spare mags. All mags seem to run fine now!

I've noticed a few things.

1) 22LR still isn't real reliable. Had a few that got hit hard a couple times and didn't go off. NOT a fault of the kit.

2) It is sensitive to the mags. As with every gun, if the mags don't feed nothing works. With this kit, as with anything 22LR, there isn't much energy in 22LR so any drag from the bolt touching the feed lips is no go. DO NOT go bending your feed lips about as that will cause more issues.

3) Brass goes everywhere. I've found brass behind the magwell adapter and under the bolt, I've had brass get wedged between the bolt and magwell adapter and I've even found brass under the tail of the sear holding the sear down. I suspect this is a bolt velocity thing meaning I need to clean the thing. I'm 3-400 rounds in of Remington Thunderbolt. it's pretty nasty.


Everyone that has shot it has gotten a giant grin and giggled. Totally worth it!
