I just picked up an AAC Tirant 45M and the piston spring that came with it will not fit around a M16x1RH AAC piston. In addition to that, the piston itself has threads so deep/long that it actually touches the face of my MK23.
I looked around online and found that a Silencerco piston spring will work on the AAC. So I grabbed a spare spring I had from my Octane and it does indeed fit and everything screws together correctly. Which is how I saw that the piston hits the face of the MK23.
I compared the AAC piston to the Silencerco version I had and they appear to be identical, except it’s actually physically longer but has a shallower thread. I put the Silencerco piston and spring in the AAC and everything tightens up as expected and the piston does not hit the face of the MK23.
So my question is, is it ok to use this configuration? I can’t find anything online about it other than the spring being ok.
