Type 81 build/conversion in 223/5.56 NATO

Made some headway - put the devices on the barrel, pressed the barrel into the trunnion. Waiting for the Brownell's solder and flux from the US to continue with the bolt mods. Headspacing won't be possible until then.
One picture shows how much longer the gas system has become - good two inches. Will need to lengthen the cover and the rod.
Will share my findings and thoughts on the magwell mods soon

What's the plan for the forend? Leaving the front sight? Refinishing barrel?........... So many questions lol

TY, was thinking of dressing the front end the way it is on the pic, kinda Cold-War era. Retainer for the wood forend is still there, just hidden inside the plastic. As for the finish, was thinking of degreasing and coating everything front of the trunnion with black ceramic/epoxy from Wheeler

That donor T97 is being transmutated into a 300blk launching machine :) The pistol length gas system keeps throwing technical challenges at me so the T81 project took precedence for being simpler and faster

Too bad! I've always thought a 7.62x39 bullpup that took AK, T81, or Vz58 mags would be freaking awesome.

That conversion would be 8 out of 10 on the complexity scale. 300blk is easier to build and is also (in my opinion) the most versatile round ever invented.
Clown Lord had created a real vacuum on the 300blk rifle market. l just wanted to have a 300blk rifle that is short yet non-restricted, capable of cycling both - subsonics and supersonics

Tell me about it, I have a brand new 300 blackout build safe queen at the moment.
 
If you want to use the barrel, gas block, and handguard , as well as butt stock and pistol grip, from a Blackout safe queen in the interim, you have a svelte future option and a brick like current option. SBI is developing a direct gas impingement BCG for their soon to be released Lynx upper, which they intend to match the sveltness of their 180 Lynx lower. The now available DI alternative that would allow the same re-use of parts is the brick like Jard J180 build kit, available by phone, email, or in store at Sylvestre Sports.
