Hey, some information for you.
The PTRS-41 and the PTRD are two different high caliber rifles.
A PTRS-41 (14.115)
PTRD
The PTRD is a Bolt-Action single shot weapon. Whereas the 41 is a Semi-auto Enblock clip fed monster of a rifle.
Just here to clear up confusion between the PTRD and the PTRS-41 for you.
Edit; Noticed it was two guns in Post. Still useful information however. (Both rifles were last used in WWII, by the way.)
OT; Great lookin' PTRS-41 rifle.
