I just got one today been using it all day and it's nice and quiet, the can is a YHM Wraith. I also cut the dual recoil springs, removed the magazine safety disconnect and put a extra washer on the hammer spring, now I can run sub-sonic ammo and it cycles reliably. I'm not going to lie it was pain in the ass and took me four hours to do it.

I took apart my Mk22 to loctite some bolts that were said to cause light strike and found that it look nothing like the older ones. Anyone know when they changed the design?

Just want to say Hi, Name is Steve. Live on the Northside of jax, on Black Hammock Island. And like everyone else on here I love guns. I joined because I can't find any info about when ISSC redesigned the MK22 bolt/carrier group.
