Misc/ form 1
I'll start with the form 1 silencers:
A form 1 (5320.1) silencer is a homemade silencer. It is legal to make your own silencer but the form 1 HAS to be approved by the ATF and returned to you BEFORE you can make it.
Form 1 .22 with description of materials used:
All aluminum is 7068 (yes 7068) and blast baffle is 316 SS
OAL is 7" , OD is 1.125" , tube ID is 1.000".
Tube is 6" , ID bored to match OD , wall thickness is .0625" +or- .0007"
The caps are threaded with 28 TPI and .375" thread length and bored out to add more volume , it uses 7 baffles , 6 K-baffles (5 aluminum and one 316 SS) and one coned washer on top of last K.
The 1/2x28 threads were cut while on the finished can and was indicated off the bore via 6" range rod
The baffles have .050" thick skirts , .062" thick necks and .062" thick faces , the baffle face has a .110" tall cone leading into the bore. The baffles are .996" in OD and have a tight-ish .25" bore that was bored concertic with the OD one baffle at a time (i had run into bore alignment issues one just deep drilling a bar and cutting baffles off of that)
For those not framiliar with 7068 Aluminum , it is exceptionaly strong and hard. I think this will make a better suppressor than 7075 and certainly better than 6061
6061 T6 , yield=35,000psi , Hardness=95 Brinell
7075 T6 , yield=68,000psi , Hardness=150 Brinell
7068 T6 , Yield=97,000psi , Hardness=190 Brinell

Form 1 .22 "K" baffles:
Form 1 monocore .22 flat slant baffle: (This is a flat disc that has a slight slant to the baffle system and it all one piece)
Form 1 square baffles: (I have no idea how this was made)
Form 1 (as far as I know) ruger mkIII integral: (The silencer has been made part of the firearm)
Form 1 staggered .22 baffle monocore:
Form 1 45 pistol dome baffles: (the maker of this silencer, ended up shooting the baffle stack and it resulted in a misaligned core. This is why it is bent)
form 1 mono-core (unknown maker):

Very first of its kind,
The isobaric monocore:
Started out as square aluminum,

Next are unknown silencer designs.
Half baffle: The idea behind this the gasses would have to follow the path of a zig-zag flow.
I really have no idea who makes this:
AK47 silencer cutaway:
Reflex silencer cutaway: reflex silencers slip over the barrel of a rifle to give the silencer more internal volume without adding too much length.
