looking for a Arsenal krinkov for a Groza conversion would prefer 7.62 or 5.45x39... Has to be a stamped receiver so pretty much limited to 107UR/104UR or there pistol versions. Willing to pay a little more for a 104 but would like to be closer to 107 pricing. Cash is in hand or if you'd rather trade i do have some stuff for that as well. Thank you!
