Thanks a bunch to the info I found on this forum I now have my Saiga 12 ready to SBS once my stamp comes through. It has been submitted just over 3 months now, so any day I should be getting it back.
I wanted to share some pictures. This is just a gloss over of the work involved but I wanted to post.
This took so long, one because I am waiting on a stamp and, Two because I work 2 jobs.
So here is a pictorial of my build:
When I bought it used it had already been converted with a bolt hold open installed
I wanted to go 12" and base on info here I decided the right thing to do was move the gas block back, However in hindsight i realize now I really did not have to pull the barrel from the trunnion....but I did. While I had the barrel out I turned it down to thread after the 12" cut.
Made a barrel pusher
welded up old gas ports and gas block retainer groove and turned barrel
profiled and polished feed ramp
Located and drilled 4 new .073 gas ports 2.25" back from original
Replaced bolt carrier with Tromix short extension
Removed old gas tube
installed Tromix Short tube. As you can see in this pic I did cut the barrel to 16.25 and slip fit and welded my old flash hider since I will not be using it when I am done.
Fit a Chaos rail system to the new handguard location
removed rear tang and added Tromix butt plate and stock
SBS ready and ready to test fire.
Took it to the range and it ran like a champ on everything I had with me.
I did some bolt reprofiling and polishing but didn't take any pics.
Once it passed function test I took it back apart and refinished it with Cerakote FDE
I have this Tromix brake for after it is cut
