PWS FSC HK Threaded Barrel Compensator - 15X1

SKU: HKP-00837

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

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

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 NJ, NY, etc.

Update - June 2018 The California DOJ has determined that this product is not legal in the state of California.

"Brilliant!"

Con W on 4/4/2010 6:43:55 PM

Overall Product Rating:


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.

Overall Product Rating:


Installed the PWS FSC on the HK 91,went on like a dream. Leveling the Compensator to the 91 was easy. Putting it through the test at the range - OMG.


"Highly Recommended"

Overall Product Rating:


These are great flash hiders, and reduce muzzle rise tremendously. Very happy to find these for my HK! Thanks Again!


"Way less recoil way louder and way more expensive"

collin schroeder on 8/19/2013 5:45:22 PMVerified

Overall Product Rating:


It drastically reduced the recoil and probably doubled the volume. I haven't tried any other brands but this is awesome. 4/5 because of the price.


"Terrific Muzzle Device!"

Gary Sutherland on 6/10/2011 10:00:54 AMVerified

Overall Product Rating:


You absolutely get what you pay for with this muzzle device! Installation on my PTR-32 rifle was easier than I expected... although due to the alignment of my barrel's threads, little-to-no compression of the crush washer was required to align the device correctly. Strongly recommend this muzzle device to those looking for something better and more physically appealing than the standard PTR flash hider.


"Outstanding-no more black eyes"

Shane M. on 8/10/2013 11:38:57 AMVerified

Used the PWS FSC HK Threaded Barrel Compensator on a PTR-91 at a bowling pin match today, What a difference it made. Not only did I notice the difference, another competitor also commented on the improvement from last match. Took home the class B trophy this time. The range director even commented that it's not to often that a .308 wins these things. The PWS FSC HK Threaded Barrel Compensator was worth every penny for me. Hope you find the same success.


"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.


"PWS comp"

Awsome product!!! Perfect fit and finish. This brake was the perfect choice for my G3K.


"I have been waiting for months! PWS Comp works wonders"

Kevin Martineou on 7/24/2009 7:01:35 PM

Overall Product Rating:


Well worth the wait and price. The Comp has helped out a ton on followup shots and control under F/A. As soon as I get my "fun funds" back I will be back for another one for my PTR.


"PWS Compensator"

I bought this compensator for my HK91 clone. Better than expected. Recoil is significantly less, follow up shots are right there for rapid fire. Very easy to stay on target. I would recommend this comp for any make of rifle.
