My best friend passed away recently, and his wife asked I help "Clean out all this gun shit"...
Reloading/ammo/arms...etc...

I came across several "TAC Trigger assembly" for SKS, AK, AR.

Never seen such a thing...after researching on the net, i still don't get it...
Turns a semi into a full??? Looks cool, GREAT idea, but......

Any advise/suggestions?
