Does anyone know of an off the shelf way to use a tri lug adapter on the new FTN.5 Rifle cans? If not, is it as simple as modifying the thread adapter insert STL to take the threads of an off the shelf tri-lug adapter?
Never used CAD and this might be the project to get me to learn. I really want a white monster can hanging off the end of an MP5
Great question. Coupler is NOT required for this new one. It’ll be pretty similar to the KAK, in that you will epoxy it into the insert.
Also good follow up question. The FTN 4.5 PCC is probably the quietest PCC can. The 19.2 oz White Monster versions will of course be functional for 9mm, but it is really optimized for rifle calibers. Because rifle gas has very high velocity, it benefits from more spacing between baffles and therefore less baffles.
You would get benefits from flow-through, and of course the meme potential is off the charts.
But if you wanted the absolute quietest PCC suppressor, it would be the 4.5 PCC. It has more baffles, and they are the new K baffles that have the extra ribbing, and ribbing on the walls for max turbulence
Hope this helps, but now that I have typed this up, perhaps this is more confusing, feel free to ask more questions if i made it more complicated than it needs to be
The explanation of the rifle cans being optimized for higher velocity than the PCC cans makes sense to me. Is the baffle construction similar between the pistol and PCC versions? Other than the pistol using a Nielson device and having an oblong bore for the slight tilt potential
Since we’re in the $0 tax stamp era, I will probably print a FTN 4.5 PCC, a FTN 5 Flow PCC, and a 19.2 rifle all in 9mm. Probably makes sense to make all 3 with cheap thread adapters and no epoxy on the insert. Then make an insert with a tri lug for my favorite since it’s by far the most expensive part.
The baffle construction is somewhat similar, in the sense that they have ribbing and slanted K baffles, although I had to do a redesign from scratch to make the off axis baffle
Sounds like a plan! Hopefully by the time you get around to it, we will have figured out the dimensions of the trilug. I sent the files to 2 other people to testfit, hadnt heard back yet
