    Suppressors Baffle erosion DT vs brake

    For non SBR barrel lengths and non F/A firing schedules, there is basically no difference. At least in our testing.

    Gunsmithing Adjusting Gas Key to lower receiver gap with a JP silent capture spring?

    Yes. If you are worried about the "Bumper" on your JP SCS wearing out, you can pull it out and check it every 500 or 1000 rounds and see if it shows any wear. If it does, you can get a new one in the JP "SCS Maintenance Kit". I have original "version 1" SCS's from over 15 years ago with...

    Gunsmithing Adjusting Gas Key to lower receiver gap with a JP silent capture spring?

    You are overthinking this. You have a gap of about 2 quarters? Can you make it hit the receiver? If no, then you are fine.

    Suppressor with a brake on it, does it help or not?

    It will still work quite well.

    Suppressor with a brake on it, does it help or not?

    The way to say that would be: Device B has 2.43x the amount of recoil energy vs. Device A. But bottom line, yes, the RR brake does have a dramatic effect on recoil energy compared to the same suppressor without. Also note that that particular graph is data from 300WM. Data from 308 is a...

    Suppressor with a brake on it, does it help or not?

    That's not now "reduction" works. If a bare muzzle has an amount of recoil energy that is normalized to 100 units, then: Device A has a 65% reduction, so it has 35 units of recoil energy. Device B has a 15% reduction, so it has 85 units of recoil energy. I think you are trying to calculate...

    Suppressor with a brake on it, does it help or not?

    Yes, you are reading it wrong. ETA-- you are dividing 65 vs 15 and turning into a percent and calling that reduction. That's not how any of that math works. What you are reading as "65" and "15" are the percent reductions in recoil energy from a bare muzzle (per the legend on the left)...

    Suppressor with a brake on it, does it help or not?

    A lot. In this graph the RR models have the brake on the end. ETA: Also, the Ultra50 recoil reduction compared to a bare muzzle on 50BMG is 65% reduction.

    Suppressors Best thread locker for muzzle devices?

    Hit with a small butane torch ("kitchen cooking torch") briefly until it melts. Remove with wrench.

    Suppressors Best thread locker for muzzle devices?

    We recommend red Loctite #272. High temp / high strength. Rocksett is not really stronger than blue Loctite, which is why it came off.

    Blue Buffer spring drama. Malfunctions with new springs. Anyone else seen this?

    I use them in both small frame and big frame AR's (different versions for each), however, I was thinking of small frame when I posted.

    Blue Buffer spring drama. Malfunctions with new springs. Anyone else seen this?

    I switched over to the JP SCS over 15 years ago and haven't looked back. It works great in everything

    Suppressors Best way to clean heavily fouled TBAC can ?

    We don't make any alternate things to put in the RR's place for reasons I have explained in detail in other threads.

    Suppressors Best way to clean heavily fouled TBAC can ?

    No, that is incorrect. The RR brake comes off. The RR technical manual shows how to remove it. We have videos online showing it being removed, re-installed, and how to clean the tapered interface between it and the can.
