The shocktech's oringless design will allow a lower LPR setting than a bolt with o'rings (my systemX with o'ringless bolt runs at 40 PSI from the LPR), but depending on the fit in your marker, it might loose you some efficiency because of the air blowing by it's sides. A bolt with o'rings will experience more sticktion because of the elastomer the o'rings are made of, making it harder to move, but it will seal the air pulse to the transfer area of the bolt, getting a few more FPS (up to 20) with the same settings as the o'ringless bolt. The jackhammer is a pretty decent LPR, it should keep up no problem.
Thank you for the information and taking time to write that!!!
