Yes. Each suppressor is considered an NFA item, and is serial numbered. So, each suppressor needs it's own $200 tax stamp. I have 5 NFA items, so I have 5 stamps. I'm in the process of registering two more AR lowers as Short Barrel Rifles (SBR) and they each will also need their own $200 stamp. It's the price we have to pay to have the cool and fun stuff. I just got tired of swapping my registered SBR lower with my 3 short barrel uppers. When it's all said and done, each of my uppers will be married to a registered lower.
Unfortunately, to make this happen, I will be selling two of my pistols to fund this project. :( I said that I will never do that again, but money is REAL tight right now.

300 AAC Blackout... maybe my new most favorite caliber
Jan 26, 2014 07:12 AM #21
Feb 09, 2014 02:52 PM #22
Test Rifle #1: 16” AAC upper with a Nikon P-300 2-7x, BDC ballistic crosshair
Test Rifle #2: 10.5” MAS upper with a NCStar 3-9x, thick crosshair
Load-1 << Winner!
Accurate AA5744 powder, 10.9gr
Sierra SMK 220gr
COL: 2.100”
Subsonic
@ 100 yards w/ 16” AAC upper = 1.28”
@ 50 yards w/ 16” AAC upper= 0.68”
@ 100 yards w/ 10.5” MAS upper= 1.27”
@ 50 yards w/ 10.5” MAS upper= 0.49”
Load-2
Accurate AA5744 powder, 10.7gr
Sierra SMK 220gr
COL: 2.100”
Subsonic
@ 100 yards w/ 16” AAC upper = 1.50”
@ 50 yards w/ 16” AAC upper= 0.72”
@ 100 yards w/ 10.5” MAS upper= 2.00”
@ 50 yards w/ 10.5” MAS upper= not tested
Load-3
IMR 4227 powder, 10.5gr
Sierra SMK 220gr
COL: 2.100”
Subsonic
@ 100 yards w/ 16” AAC upper = 1.42”
@ 50 yards w/ 16” AAC upper= 0.69”
@ 100 yards w/ 10.5” MAS upper= 1.50”
@ 50 yards w/ 10.5” MAS upper= not tested
Load-4
Accurate AA5744 powder, 17.8gr
Hornady 150gr FMJ-BT
COL: 2.140”
Supersonic
Load-5
Accurate AA5744 powder, 18.9gr
Nosler 125gr Ballistic Tip
COL: 2.165”
Supersonic
Load 4 and 5 were inconclusive. They are Hornady 150gr FMJ-BT, and Nosler 125gr Ballistic points. Both were supersonic loads. The scopes did not fare well for target shooting, and the groups could not be controlled. Of the loads, the best group was 2.00” @ 100 yards shot with the 125gr Nosler ballistic tips, fired from the 16" AAC upper. I felt that I could have done better if we had a better scopes with finer crosshairs. Neither one of these scopes were made for target shooting.
Ironically, the 10.5” MAS Defense barrels and upper I built actually performed better than the 16” Advanced Armament upper! The groups were tighter and the velocities were more consistent. With Load-1, the subsonic loads actually went supersonic on your 16” AAC. The velocities averaged 1,141fps. On the MAS 10.5”, it averaged 1,064fps. I’m confident this is because our load data was based on .223rem brass, and the majority of the brass we had were Lake City 5.56 (smaller internal volume = increased pressure and velocity).
This has been an interesting process. We decided to stick with Load-1 and production has begun. We will be mounting a better scope on the rifles and testing the supersonic loads again. I am REALLY hoping that the 125gr Ballistic tips do well. I like that bullet.

and the can on my long gun

The pictures didn't come through. Check your link.
Feb 12, 2015 09:04 PM #26
better? trying to figure out the linking from google drive. not easy like photobucket used to be.
Feb 12, 2015 09:15 PM #27
yeah i dont think google drive will let you link unless you have it set public
google has the picasweb album that should work though

super gay. It was set to public but it looks like the picture changes servers or something. It works for a while and then doesnt.
im sure the "link" to it works, but you cant IMG tag it https://drive.google.com/open?id=0B7WWbRF6wAgKbXR4bHBMRUgtT1U&authuser=0

Hey, is that a SWFA-SS scope on your bolt gun?

Nice. Good scope. I had two of them. Now, I have their 5-20HD.
