For sale or trade:

8.5 inch 300BLK Jakl upper in smoke color. Under 300 rounds through it.

Hand adjustable gas system, long stroke piston operation. 

Comes with adapter kit for standard AR lowers to run this upper along with a jmac customs folding stock (not brace). 
The adapter screw is beat up from removing it from the factory PSA Jakl lower I had this on. Could be used again, or you can purchase a new adapter kit from PSA. 

I ran it suppressed as an SBR but want to play with something else. Would trade for a sub 12 inch 5.56 or 300BLK standard AR upper. Will sell the stock separately.
