Buffers & Springs

Does an H1 or 2 buffer cushion the action and parts with a suppressor attached? I have a Colt CAR with a can and it appears that I have bent the firing pin retaining pin using the suppressor. Any thoughts?

Firing pin retaining pins get bent up regardless of whether or not you use a suppressor. Actually if you use a shrouded firing pin carrier it'll happen less. Yes a heavier buffer helps with recoil whether or not a suppressor is attached. The suppressor won't change the fact than a H and H2 is heavier than a CAR buffer.

Cool. I will get some spare pins and be GTG. I'm not concerned with the recoil, just the increased (?) wear and tear from the added back pressure from my can. That's why I was wondering if a H1 or 2 buffer would be a good idea. The rifle works 100% so if I don't need a heavier buffer, I don't want to get one. Just don't want to tear up my gear. Your thoughts??

Does anybody knows the weight of each tungsten & Steel weights in H series buffers? what does reciprocal weight means? Thanks.

I forget the weights, but the reciprocal weight is the weight of all the parts that move inside the buffer when it bottoms out or closes into battery.
It's the weight you feel moving when you shake a buffer.

The steel weights are .7oz and the tungsten weights are 1.5oz
CAR buffer = 3 steel weights
H buffer = 2 steel weights, 1 tungsten weight
H2 buffer = 1 steel weight, 2 tungsten
H3 buffer = 3 tungsten weights

So If I wanted to switch between a carbine upper and a rifle upper sounds like I would need a rifle lower to be safe and swictch to a carbine buffer, spring and spacer when I was using the carbine. Sounds like putting a carbine on a rifle lower may overdrive the system without those changes. Correect? Or is there another combo?
