Critique my .22LR design
30mm OD 25mm ID main tube with 2.5mm walls internally tapped to M27-1.5
The ID will need to be skimmed to 25.4mm for the tap and for the 1” freeze plug baffles and spacers.
6.5” long overall
Front cap is in 2 parts. 1st sits inside the tube to compress the baffles to the rear and center them against one another. Then the front cap threads over and flush with a shoulder.
Rear cap is similar except has a direct thread 1/2 28
Things I might change:
The blast chamber is small. I would probably just reduce the angle on the 1st baffle.
My front cap assembly may be changed to make tightening the inner threaded ring easier. Possible having male threads on this part also that the front cap threads to. Current intended on tightening with a custom pin spanner wrench
Planning on clipping the baffles with a jig.
Designed specifically to minimize machining on a lathe while keeping concentricity
