HK MP5 22lr STD made by Walther. I have over 900 dollars invested in this rifle. I am asking $750.00 This is a great rifle. I have used it minimally. Probably 150 rounds. Comes with UTG bug buster scope, mounts for scope, picatinny, strap and 600 rounds of ammo. No scratches or dings. Basically, brand new.
