Carbine Buffers

Wow, am I going to expose myself.. as a newbie!


I see you have Carbine Buffers:
LMT Standard 2.8oz
LMT Heavy 3.9oz
CMT H2 4.6oz

So, from you or anyone else here:
1) Do these buffers really reduce felt recoil;
2) Do they affect performance;
3) What are the differences between these 3 items?

Thanks for supporting CalGuns!
