Just bought the FSB on right and the booster on bottom of pic. Is this the proper 5.45 booster and FSB for a 105 build?
Had to go to hell and back to get it, want to make sure its all good for a rusky build. It looks kosher to me, but would like another opinion. I have another pic, but honestly I am surprised I got this one up.

The fsb on the right is corect, the booster looks right as well.

thank you gentlemen, for the help. I bought these from a reputable source, but having never handled one myself wanted to make sure. Living in Cal. I need to pin on an extended brake. I was thinking of the extended booster. Does anyone know where I can pick one of those up?

Here's a company that has extended boosters:

Thanks alot Rogue. The faux bulgym 4 3/4" booster is exactly what I'm looking for. Any truth to the fact AA-OK has passed off air soft equip. as centerfire grade equipment?
Any members with a pinned barrel feel free to chime in: Is it easier to clean with this brake pinned versuus the bell booster, or is there a better one to pin?

Keep this in mind when building a 105 with NFA pinned booster/bbl extension:

1. Might as well be a full length bbl, no need to clean the fake extension.
2. Russian 105s require the the journal for the FSB to be turned down
3. Russian 105s have a shorter FSB to gas tube extension for unique gas port location.
4. Bulgarian 105 FSB utilize existing gas block location and standard 74 bbl journals
5. Russian 105s are shorter overall because of the unique FSB, Russian authenticity would be negated by the need for an NFA bbl extension
6. Bulgarian 105s are significantly easier and less expensive to build.

btw, wth is that two-piece FSB in the middle of your first photo?

Right on sneaker, that cnc warrior 4pc. booster looks tight. I've bought from them before and they build a quality product...and $20 cheaper. Thanks, bro

He219, if you compare the fsb is the middle with the one on the right you'll see they're essentially identical in features. But, with the middle fsb I think threads etc. have not been pinned on yet. If you look at where the gas tube articulates into the fsb you'll see a pkg. of what looks like parts/pins to complete it. So, I think its a uncomplete rusky.
So if I use the 4 3/4" bulky type booster will it bring the barrel to 16". Also this booster will not cause issues if I try to remove it? Or if I run X thousand rounds through it, the booster won't get stuck on the fsb threads? I wont be running corrosive through this AK105, at least until I can put on the orig. booster to clean properly. Thanks for your help, I really want to do this, but want it all correct. Ill wait to get to a free state if it cant be done right.

P.S. Anybody recommend who does the best AK work, and who has the paint that best mimics Russian milspec?

[sqhammer]

He219,, I spoke with the owner of the fsb you asked about. Hes a russian national and has decent access to these type things when he puts his mind to it. Anyway, he said the first AK10X fsb's were built in pieces then assembled. Thats why you see the thread adapter over the barrel unattached. The newer type is one solid cast piece. That is the type I have. I checked and it has no pin on 24mm threads.

The Izhmash AK-74 Parts Kit that Rguns is selling have the two piece fsb on them as well, they are also press crimped. Trunnion on mine was marked 88'.
