My first stock broke after a month of short travel to the range and back. I am going on 9 months with the replacement stock.For me it has held up a lot better.
Legacy Sports is apparently now the importer for the M22 and MK22. If you have any issues that need to be addressed, just head to http://www.legacysports.com/repairs/repairs.html Just figured I would let others know.
I removed the magazine safety on my GSG 1911, and it goes to half cock and full cock when I pull back on the hammer. I would probably try to re-install the main spring housing, something doesn't sound right.
Where I live in Wisconsin, they are 1.99/box of 50. Sometimes you can find them at 1.70 if they are on sale. They are the exact same price as Federal Champion, and more than Federal Lightning.
My friend has the mp 15-22. Its a really nice weapon. I wanted something different so we can trade guns and have a different shooting experience from time to time.
Got my MK22 last week and have the same issue with the fore sight. I am going to have to try your fix for it. I got lucky and have a stock without play. ;D
