jmorris Posted March 5, 2016 Share Posted March 5, 2016 After looking for "uppers" for one of my TC contenders for my Daughter and not liking the prices I decided to build them. Started with the .22 blank and turned it down and threaded it for a suppressor. While I was at it, I went ahead and machined a thread protector if it ever didn't have one on or a QD adapter on the threads. After a little searching, I couldn't find any weld on lugs (one source for threaded) and machined my own just averaging the measurements from the TC barrels I do have. Welded the first one together yesterday, chamber reamer is on the way now and after that will have to machine the slot for the extractor, finish and test. If it is a "winner", will do the next one the same way. Link to comment Share on other sites More sharing options...

practical_man Posted March 5, 2016 Share Posted March 5, 2016 I a amazed by your ingenuity! Thank you for sharing your achievement. Talented machinists are a blessing to our society. They are truly under appreciated. Link to comment Share on other sites More sharing options...
mscott Posted March 6, 2016 Share Posted March 6, 2016 I've had pretty good luck with Green Mountain blanks on several projects, so I imagine you will be happy with the results. Nice project you've got going Link to comment Share on other sites More sharing options...

jmorris Posted April 4, 2016 Author Share Posted April 4, 2016 Well I finally had some time to play with this project again and modified a G2 forearm to work with the original frame and mounted it an and optic banged away at some steel until I had it close enough to put a group on paper. Not the best shooting 22 I have or the easiest to bench for groups because of shot to shot movement but the first photo is a 20 shot group at 60 yards (odd distance but just how far it is from the back door to the bullet trap). For the Kiddo I mounted an aimpoint comp3 I had and even with the suppressor it's shorter than the 510 she has been shooting. And yes I used one of my Miller synchrowave TIGs for the welding.

joelpend Posted April 8, 2016 Share Posted April 8, 2016 I would think it needs stress relief after the welding. Link to comment Share on other sites More sharing options...
