Sigmaco T81 AR stock adapter

Sigmaco T81 AR trunion, collapsing AR stock with QD sling mount. Used excellent condition.

Includes folding mechanism (used good):

I personally think the fold mechanism is garbage (weak spring) so I am not including it on price. But the part is included nonetheless. 

In my opinion this stock works best installed without the folding component. It is rock steady with as a fixed, collapsing stock.

$20 shipping (Can Post basic insurance) to the majors and I combine ship for multiple purchases. Winnipeg locals can meet in Lockport for pickup.
