JP Compensators

The JP Compensator was born out of the days of the SOF (Soldier of Fortune World Championship) series matches. After enough pressure, match administrators finally allowed compensators but deliberately disqualified our classic JP Recoil Eliminator with their 1" x 3" dimensional limitation. That has carried forward in all subsequent matches. In its own way, it was a compliment to us for offering too effective a product, but it didn't stop us from developing a brand new compensator that, even at a smaller size, could still perform recoil reduction wonders.

Working in other professional shooters, we arrived at last at a truly high-performance, match-legal rifle compensator that maximizes the potential of the common size limitation while maintaining nearly the same recoil reduction and neutrality that characterized the original JP Recoil Eliminator. To this day, the JP Compensator is the standout most efficient device of its type. Since its release, the JPTRE series has grown well beyond its competition origins. For years, it's been the choice of shooters who prefer a slimmer, more compact configuration without crossing over into a more tactical aesthetic.

Large-Profile Compensators

For those who prefer the slimmer, more conventional appearance of the JP Compensator line but who demand maximum performance truly on par the effectiveness of JP Recoil Eliminator, the TRE-5 Series of our compensators fits the bill. At 1.2" outside diameter, these compensators don't meet the 1" x 3" restriction that spawned the original JP Compensators, but for the duty use, hunting, recreation, or most any other use, the TRE-5 Series offers a slight edge on performance over its little brothers without a radical aesthetic departure.

The JPTRE-5 Series compensators are available for .750, .875" and .925" barrel diameters to allow for a precise blend to the most common barrel profiles.

Tactical Compensators

"Tactical" has been the watchword of the AR business for several years with many shooters preferring a more duty-ready appearance in their AR. Not satisfied with many of the more tactical compensators available, we had to make our own but without sacrificing the reputation we had for recoil reduction solutions that goes back over twenty years to our original Recoil Eliminator. Even as the smallest JP comp. yet in terms of OD, we're pleased to say the Tactical Series can still stand with the best, providing dramatic recoil reduction with no accuracy degradation.

Available for both .223 and 9mm, the Tactical Series comes in sub-.875, making it NRA Law Enforcement 3-Gun legal. Each model is also pin-and-weld ready with a pre-drilled barrel shroud and included pin to jump your 14.5" barrel up to the legal 16" configuration.

FAQ

How do I know which compensator I need?

Refer to our selection guide. First, you will need to know the threading of your barrel, which is usually 12-28 for an AR-15 (.223/5.56) and 58-24 for an AR-10 (.308/7.62), though there are exceptions. Second, you'll need to measure the outside diameter of your barrel. We have muzzle devices to accommodate several ODs, but if we don't offer one to match yours barrel exactly, it's best cosmetically to choose a comp. that is slightly larger than the barrel and then break the transition with a jam nut or crush washer. Some of our comps. include a crush washer, which will be indicated in their descriptions. Finally, you'll need to mind the exit hole required for the cartridge you're shooting. On most cases, the exit hole can be opened to accept large cartridges.

Do you offer installations of your comps?

We no longer perform this service onsite, but E. Arthur Brown stocks our compensators and can time and blend them to your barrel.

How will your comp work with my rifle?

Comps are designed to work by redirecting gas, and ours are most effective when used with an overbore Magnum with a large case for the diameter of the bullet such as .300 Win Mag, .300 Weatherby, .30-378 Weatherby Magnum, 6.5 x 284 Norma, etc. While still effective, the performance difference is less dramatic with large, heavy bullets and straight-walled cases.
