I upgraded my Ruger Mark IV 22/45 Lite to meet all the specifications of the new Volquartsen Mamba. LLV-6 upper and Vortex Red Dot.
So, there it was, just sitting in the safe, the old upper. I found a vender (Wirthwein Guns) with a new lower frame and ordered it. Now I had a second 22/45 Lite but it needed a trigger job.
It wasn't bad, 3 3/4 pounds, but wasn't that good either.
I ordered the VQ accurizing kit and installed it Thursday night. Took me about 20 minutes and ended up with a 1 1/5 pound trigger. SWEET.
Today I took it to the range and fired 300 rounds of CCI Blazer and a box of CCI SV with 5 of my spare magazines and I got 100% reliability.
All I need now is a new Red Dot sight.
