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


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 NJ, NY, etc.

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

"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.


"Best Brake for your HK91"

This addition provided the single biggest improvement to my rifle. No more bruising when firing the rifle.


"Tried it Best Comp/MB for HK rifles I am sold!"

Kyle on 11/13/2009 7:34:19 PM

Overall Product Rating:


Bought this based on the feedback I heard from others. The install was a breeze on my PTR91 and my HK91. The felt recoil has been reduced by a large measure. And to top it off my guns now look that much cooler. I love it so much I plan on adding them to all of my HK rifles! Thanks, HK Parts.net you truly have the goods.


"Great although it needed a little closet gun smithing"

I love this flash hider I had one installed on my Mark 14 EBR Mod 1. It is amazing how this thing works! Primary weapons systems have really nailed the compensator market. The problem I ran into with this compensator. Is that I had to do quite a bit of closet gun smithing to fit my Cetme.


"Looks great, will it perform?"

Ross Isenberg on 10/5/2011 9:57:27 AMVerified

Overall Product Rating:


Binded by awful Connecticut state law I have not put the compensator on my rifle yet. I need to have the current brake unwelded and then this one welded on. However, I can comment on its fit and finish which looks fantastic. I can also comment on its attractive aggressive styling which looks like it is something out of a Star Wars film. It comes with an o-ring, a direction set for mounting, and the compensator itself. I will post an updated review when I have shot it on the rifle.


"Cant say enough good things!"

This comp is the coolest lookin comp I have ever had. Not only that it tames recoil like no other comp that i have used before. Awesome product!


"Tricky to install but works well"

Bill on 12/9/2012 11:28:07 AMVerified

Overall Product Rating:


This is supposed to be the one to get for the HK91/PTR91 platform so I gave it a try. First, the cons. It is somewhat difficult to time. Long story short, I could only get to about 3/4 of a turn before the timing point without using a vice. Less was too loose, more was impossible without a vice. I do a lot of AR work so I had barrel vice blocks on hand. Unfortunately, they don't work with this platform. If I were going to do a lot of installs like this, I would cut down a set of AR barrel vice b... More details


"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.


"Great MB"

Love this MB. Great addition to the rifle and it looks good too. Highly Reccomend.


"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.
