I have built a few form one cans. Almost all of my completed ones are all stainless except for the spacers, so they were a little cheaper then the ti builds above. I also have access to a buddy who works for an SOT in a machine shop, so I get my machining, engraving and coating all really cheap. Even with all of that once my next few form one cans are done I will probably buy commercial for a while because of the awesome deals you can get on them now.
I currently have built:
5.5in 5.56 can that mounts to a yankee hill flashider. It's all stainless except for the ti spacers. It is loud, but I can shoot my 10.5 without ears and it only adds a few inches to the weapon.
10in 5.56 can that mounts to a 2.5in reflex mount. It's all stainless except for the ti spacers. It sounds really good for a 5.56. Kinda like a wanna be ops spr can.
6in 9mm 3lug, all stainless except for the ti spacers. Kinda like an omega 9k before they were available.
8in 30 cal can with 2.5in reflex that lives on my 8in blackout sbr. Sounds great and adds less then 6in to the weapon.
10/22 intergal. Stainless bull barrel was machined into a mono core with a ti tube slid over and secured with a thread protector. Sounds good, but I am gonna tweak the way the mono core is cut. A gemtec mist would have been cheaper.
I also helped my gf with a 6.5in 5.56 can for her 10.5 ar. It mounts to a yankee hill mount and sounds pretty good, noticeably better than my 5.5in.
I have stamps pending for an 8in 30 cal using a ti tube, end cap, yankee hill mount, spacers, and stainless baffles. This was built with left over parts and stuff I got used. It will be fun to shoot head to head against my sdn6. Also two large 1.625x 10in 2.5in reflex 9mm cans to live on my gf and I two 5in barrel 9mm AR sbrs. These have stainless reflex mounts, aluminum tubes and ends caps, ti spacers and stainless baffles. I am hoping they are stupid quiet.
I have other parts for a few possible future projects, but IDK if I will do anymore after these. As you can tell they are all for a specific roll and some when I started them did not really have a good or inexpensive commercial option. But now you could get a commercial version of anything I built and probably not spend much more and might even perform better, but then you could lot tell people you made them.
