@Wo1f as he is the originator and a huge font of knowledge but I can't see how it could cut the bucking. The edges are not severe enough and the distance the bucking will push into the concave is not enough to cause damage. Just my opinion of course.
On another note, having changed my barrel from standard to an Olga 6.05 250mm with the Modify Tan bucking and SixG super nub. I was wondering how it would increase my FPS. Having been cronoed the previous week at UCAP The Bunker using Abbey Vortex with .2 tracers at 270 FPS. Back at The Bunker on Wednesday using the same gas and the same .2 tracers it is now coming out as 300 fps with a deviation of 2 fps either way over 10 shots. Very consistent.
One moment of note, I was guarding an objective and aiming down a long tunnel. We could see the enemy creeping along in the dark. One of my team mates stated "Don't fire yet as you wont reach them". Basically he had just shot and reached about half way (He had spent 5 minutes listing all the upgrades he had fitted whilst in game!). Like a red rag to a bull, I took aim and fired a single tracer round, it rocketed down the tunnel with no deviation, sailed past the point matey boy's AEG shot dropped to the floor and cracked the lead guy in the chest plate. "Hit"... and the rest of the tangos scurried off into the darkness. Followed by a "Hmmm, wow" from the guy behind me. He collared me in the safe zone asking question after question. We may have another convert.
