I remixed this into a threaded barrel for a TM hi-capa 5.1, without modifing anything about the barrel itself, only splicing the thread on. For me personaly there was a little filing to do, but not to much. Biggest problem was the tab going down from the "chamber" that was somehow too bent to the exterior, which i fixed by inserting the inner barrel and hopup assembly and simply heating it up very carefully with a lighter and the pressing it to the side of the hop up until cool and firm (be carfeul not to burn your finger if you decide to do this). The suppressor anly thread 2/3-3/4 of the way on the thread but it is enough to be honest. If i were to do this again i would scale to 99-98% which should probably make for less filing if any and make the suppressor thread all the way. Print standing up right on the "chamber" and use supports (supports not necesary on the threads tho) Thank you for such good models!
P.S.: the photo with masking tape was for painting later.
