Got a couple questions about two totally different rifles here...
A guy whose land I hunt on recently had me take a look at his Remington 12A (pump action .22 LR) because it hasn't been working right. I took the thing apart and found that the firing pin had snapped in half (it had apparently been welded in the same spot previously), which looks to have been causing the rim of the cartridge to get stuck under the front edge of the firing pin, keeping the cartridge from loading into the chamber correctly, prior to the firing pin actually breaking in two. So I ordered the replacement part as well as all the other parts that have to do with the firing pin (spring, guide, retainer pin, etc...). Now I have some other questions about this rifle as it's the first time I've worked on a 12A before...
There's a fair amount of slop between the "lower" (stock/trigger group) and "upper" (receiver/barrel group). These groups appear to be held together by a single captive screw in the upper that passes through a coaxial hammer pivot pin in the lower. Does anyone know of a relatively simple way tighten up the fit? Also, what do the two small screws on the top of the "lower" (just ahead of the stock) do? For the life of me I can't figure it out. I'm hoping the rifle isn't missing any more parts, but it's darn near a hundred years old and has seen better days.
And on the G3 clones, particularly the PTR-91...
I've been waiting for over a year now (between financial setbacks and them being unavailable) to get my hands on a PTR-91. It's looking like I'll finally be able to get in the next couple of months. The question I have is about the selector switch. I was looking at a picture of a PTR-91 broken down and it looks like the selector switch might be reversible. Anyone know if that's true? I'm guessing not, but if it is, it would save me a little grief on account of my left-handedness.
