PMM 509 Ultra (dual port) JTTC and Barrel Combo for the FN509, 509T and 509 Midsize
We will not sell just the comp, The overall length and thread length on our barrels are much shorter and these comps will not install or function on any other barrel.
THIS BARREL AND COMPENSATOR WORK WITH THE FN509, 509T and 509 Midsize SLIDE ONLY.
***You need to run the yellow recoil spring with this package! If you do not have a tactical you will need to purchase the spring***
The PMM JTTC ULTRA for the FN509, 509T and 509 Midsize uses a factory FN barrel that we custom machine in-house, designed specifically for mounting the PMM JTTC ULTRA Compensator and is finished in a DLC coating.
All PMM JTTC compensators mount much like what is found on all modern rifles utilizing a combination of shims and proper timing of the compensator in relation to the Pistol slide.
the PMM JTTC ULTRA for the FN509, 509T and 509 Midsize utilize a dual port design at the 12 O’clock position which maximizes the effectiveness of the compensator in keeping the muzzle of the pistol down and allows the slide to “track” faster and more accurately for follow up shots.
The PMM ULTRA JTTC was designed to work with most factory loaded ammunition and yields and average 50-55% reduction in muzzle climb with 115gr UMC!(please refer to testing charts at the bottom of the product page)
We have adapted our designs to integrate with and complement the design of your pistol so no longer does a compensator have to look like an afterthought slapped on the end of your pistol, Rather it Delivers unmatched performance and looks.
This compensator is the same physical size as our single port so if you have a holster, you can still use it without modifications.
