Finally got this done.  Bear Creek 10.5.  7.62x39 barrel turned down to .625 fwd of the handguard ring.  Adco taper pinned the JSE FSB.  Upper was blasted at one point and anodized a bronze color, unknown maker.   I added cerakote mixture and simulated age and wear.  The lower was an 80 I engraved, cerakoted burnt bronze, then a grey, green mixture over top, then wet sanding.
   Colt grip, 7.62x39 mag and handguards. Ace metal coated stock.  JSE flash hider pinned and welded.  Not a fan of it, but it's all I could find with the bigger 5/8 threads that was long enough to make it 16".   It needed a semi carrier and a light buffer to run with surplus ammo.  
 I still have to put more rounds to see how it groups.


 

Very cool

That's pretty slick. I like it. Nice job!
