I am considering getting one of the PTR 91s and understand they are pretty reliable compared to some of today's .308 rifles.
I'm new to roller lock guns and just got an SP5K
My question is, how often do these rollers or bolts need to be serviced
I'm sure I can find cleaning and maintenance videos but wanted to get an idea of how long they will run before service/ new bolt
But, then I know there are guys out there that only clean when it stops working.
