Just doing it for the team

. The Sport Fans and one for the T fans too.
I'll shoot my Sport as it sits now first. I'll swap out my stock buffer to an H-2 buffer,then your hyd buffer after I shoot with each buffer.
Grover's Sport is "loaded" his way. So that report will tell how his works.
Bill's is set up his own way too. His report will give his story.
Then I'll swap my quad handguard and G-Shock buttstock,back to stock handguard, stock buttstock (to keep our's closer to the same weight) and shoot with your hyd buffer,then back to my t-2 buffer,then stock buffer again. That can be the M&P Sport comparisons with "almost" the same weight Sports.
Right now,mine is a bit nose heavy with the quadrail hand guard,scope,G-Shock buttstock,off set BUIS. I haven't zero'd the scope yet or loc-tite the handguard,so not a big deal taking them off and it gives a bit of a loaded down view too.
I'll switch my T's G-Shock buttstock,back to the original stock and do a stock buffer,t-2 buffer and the hyd buffer with that one too for the "T" fans. It's a bit heavier than the Sport anyway.
I don't think my G-Shock will make much difference either way,but it does take up some recoil with its built in buffer. More for 308 over 5.56.
