Good final result, but difficult install
First let me say that I have several 10/22 Volquartsen products I am very happy with and, once installed, this one appears to perform well with improved trigger pull, but the installation was painful (at best) on my MarkII, Note: I have a mechanical engineering degree and am very mechanically inclined, and with plenty of detailed videos online highlighting the process, you would think this would be pretty straight forward (although at one point you are going to wish you had three hands the size of a gerbal). Anyway, once installed my safety would not actuate. After some extensive troubleshooting time (i.e. re-installing the original parts to check function, then progressively mixing and matching old vs new hammer, sear and safety assemblies and reassembling after each iteration (which is the tricky part of the build) it became obvious the slot/hook on the safety bar, had an interference fit with the new sear. End of story, I ended up having to remove material (which took another couple of rebuild passes) on the stock safety hook so that new sear could engage properly without excessive force. Once this was done, everything was fine, but I bought this "drop in kit" so I wouldn't have to do any fitting or smithing. Given the time I spent I could have probably done a home built trigger job for far less money. After my experience, I can't really recommend the kit as a drop in scenario...
