I got my Gemtech GM22 can a few weeks ago and I didn't have any hosts for it. I ordered some TacSol parts and converted my Browning buckmark 22. I also added a Volquartsen extractor as well. It came out nice and sounds great. A buddy of mine did the cheap trigger fix on it last year. It breaks at 1.5 pounds
I have also ordered the TacSol 22 SBR upper(Kestrel). Can't wait to try it out as well. Next will be a rebuild of my 10/22.
