grayfox Wrote:Are the pistol buffer weight and spring the same wts/sizes as carbine buffer/spring?A short answer to that first question is ....yes. Pistol and carbine reciever extensions and their contents are(or should be) the same lengths and sizes.
As I look into a Grrr pistol my concern is ability to stabilize it during the shot, obviously there won't be a bench/bipod out in the woods (like at the range)... so.... pondering, pondering.
...I need a new cool-looking emoji-thingy that means "pondering..." hahahaha!
Thanks!
Pistol and carbine gas lengths for barrels are completely seperate and have nothing to do with carbine or rifle length reciever extensions and buffers.
For example:
My 8" barrel pistol gas 300BLK began as a pistol. It's lower had a KAK pistol reciever extension containing a carbine spring and carbine weight buffer and an original Sig brace. Perfect function. When it became a SBR the only components that changed were the reciever extension and a new stock on a tax stamped SBR lower.
My 12.7" Grendel barrel has a carbine gas length and will begin its life over the very same pistol lower that the 300 BLK did.
Also you can run rifle gas system barrels with carbine extensions, springs, and buffers no problem.
Springs and buffers are mostly related to what length reciever extensions they are in. You can get into playing with buffer weights to modify recoil without changing spring and extension tube.
Hopefully this makes some sense. I'm sure others can say something similar even more clearly.
