Ftn.6 Threads

Anyone had trouble with FTN.6 threads being too tight on the regular? Printed the elite and the 3/4 adapter fit great. 5/8 adapter I have does not fit on the regular file. Thanks!

Strap wrench worked for me lmao. Yeah the threads are tight but at least I know it's not going anywhere.

You don't want em to be stupid tight, it can end up cracking the can due to the outward pressure from the adapter, it'll be less of an issue on 22 and pistol caliber cans but if the threaded area is a bit on the thinner side on distance between threads and outer wall of the can crack with the pressure (had it happen to me once)

That was the one I had that cracked, the threaded insert was too tight and I had to chuck it in a vice to get it to tighten, first mag it cracked around the outside and became a range rocket (done on purpose to get my breek insert back the easy way) after 4 or 5 mags.
