PWS FSC HK Threaded Barrel Compensator - 15X1

SKU: HKP-00837

PWS HK FSC 91 Compensator - Gen 2 - 15 X 1 Threads

Our much anticipated 2nd generation HK Comp is here! With 2 new additional features:

Internal crush washer that allows for perfect fitment on the widest variety of factory HK and aftermarket barrels. Such as those found on the following firearms HK, PTR, CETME, SAR8/3, Clones & other custom builds. Each PWS comp also includes the tried and true HK style retaining ring for splined barrels such as those found on non- PTR barrels.

Between these 2 new innovations this is now the finest PWS HK compensator ever made. Ideal for all .223/556 & .308/762 caliber HK rifles. The PWS compensator tames recoil and keeps you on target. The PWS compensator achieves easier and faster followup shots than other muzzle brake devices. Adds an aggressive look to your rifle but TAMES the recoil like no other!


Compatible with all HK style models with barrels threaded 15 X 1 :

  • HK G3, 91, CETME
  • PTR All Variants
  • HK 93, 33, 53
  • HK MR762
  • Other HK rifles and pistols with 15X1 threaded barrels
  • Custom HK clones and custom builds


This is the most effective compensator available for HK rifles period!

We offer healthy quantity discounts on multiple units.

Specifications of the PWS HK Comp:

  • 2.55 inches in length
  • .22 mm diameter
  • 15 x 1 right hand thread
  • US 922R Compliant Part

The FSC91 Tactical Compensator has all of the compensation of the standard PWS DNTC compensator combined with enough flash suppression to keep the flash out of your optics & line of sight.

The PWS FSC HK Compensator has been classified as a non-flash suppressing device by the BATFE. This item is also legally considered a compensator. (see attached BATFE approval letter.) Great for those living in CA, NJ, NY, etc.

"Amazing"

Zombag on 1/6/2013 3:37:32 PM

Overall Product Rating:


Did a back-to-back comparison with a stock HK flash hider and this PWS brake on a 16" PTR 91. Felt recoil was reduced by at least 50% with the PWS, making the 308 carbine a pussycat in comparison to the original setup. Be aware, though, as with most muzzle brakes, this thing will make your rifle LOUD to bystanders. A few rounds at the range and I had people next to me fleeing to cover. It is really that loud.


"416"

After emailing the manufacturer 3 times and being promised the FSC91 would fit the 416 10.4" I ordered one, tried to put it on and what do you know...DOES NOT FIT!
HKParts.net Answer: Marc you are right the PWS FSC91 does not fit a HK416 you need the PWS FSC556. Call us up and we can exchange yours for a PWS FSC556.

"Brilliant!"

This is a brilliantly wicked comp. Had one of the older ones on my AR and it worked great. Now they make one threaded for my 91. Now i can deck out my HK as well.


"Very Effective"

M Matias on 1/15/2015 12:51:44 PM

Overall Product Rating:


Very Effective at keeping muzzle rise at a minimum with the ability to make up shots quick with the ability to keep sights on target. I did add a heavy buffer before adding the FSC91 and didn't notice any changes in the recoil or muzzle rise till I added the FSC91 so I'm not sure if it was a combination of the two or the compensator by itself.

This is the most amazing muzzle brake/flash hider I've ever used. It really does both. I ordered one for all my HK-91's and clones. On the HK's I had to clearence the inside shoulder that goes over the knurled part of the barrel by .002" it did not take long and whatever you have to do to use this brake it's worth it.


"Wicked looking to keep it legal"

This thing looks evil! It fit the HK91 threads perfectly. I couldn't tell if it helped recoil, but it did add another 922r part to my build.


"Excellent!"

Fits perfectly on my HK MR223A1


"Outstanding muzzle device for PTR91"

Maxx Taylor on 6/18/2013 2:27:30 PM

Overall Product Rating:


I had one of these on a "CAI Cetme Sporter"...I could not make it fit properly, but it certainly did reduce perceived recoil when it did stay clocked. Now, I have added one to a new PTR91 and it fit perfectly. I understand that the crush washer that is included is designed for the contour of the PTR barrel. That said, the reduction in perceived recoil is almost "magical", not only for comfort, but for being able to control this beast of a rifle. If all of that is not enough, I test fired the rif... More details
