OP4

Finally swapped out the body on my old TM M4. It was cracking all over the place, sounds like it was gonna explode in my hands at any second, lol. Grabbed a PTS receiver in HK. Took a little work, but everything fit in the end. That Systema gearbox is still shooting strong. Not much left of the original gun, just the stock pipe, dust cover, fake bolt cover, charging handle and trigger. Still serves me well.




Here it is pre-install, worse part is getting the connector off to slide off the rail.
