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

Internal crush washer that allows for perfect fitment on the widest variety of factory HK and aftermarket barrels threaded. such as those found on the following firearms HK, PTR, CETME, SAR8/3, Clones and custom builds. Each 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 and .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!

  • HK G3, 91, CETME
  • PTR All Variants
  • HK 93, 33, 53

  • 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.

Comments and Suggestions: Well I read some people were having difficulty getting this brake on, and since I ordered a heavy buffer anyways I dropped my ptr-91 off for the gunsmith to install the brake and buffer. He said it took longer to install the buffer and the brake was as easy as screwing it on and putting in the set screw. I have not shot it yet so I cannot speak on performance but the craftsmanship is great on the pws brake and it looks cool as hell. I hope I can edit this later after some trigger time.

Comments and Suggestions: Before I could see why the Germans call the collapsible stock "The meat hammer". A great flash hider/muzzle brake. Not too gaudy, recoil was cut down by 2/3's. My rifle now feels less than an AK, even with A collapsible stock.

Comments and Suggestions: The Compensator is awesome. The instructions are not. I ended up installing without the supplied crush washer on my PTR91F simply because the threads wouldn't start with the washer on the barrel.It's on there with high strength locktite and is timed and tight.With normal loads there is very little felt recoil, and with Hot loads the bruising on my shoulder was noticeably less. I think I'm done with the hot loads. Comp is awesome, and makes a great rifle even better! kudos to KH Parts, PWS, and P... More details

Comments and Suggestions: 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.

Jeff Meyers on 6/18/2013 7:22:25 PM

Stars Rating:


Comments and Suggestions: HK Parts Service-Excellent. Havent tried the rifle with this muzzle brake. But have used the same brake with 5/8x24 pitch on a bolt gun. Makes a real difference. The PTR91 is a heavier rifle than my bolt gun, so the recoil and climb should be significantly reduced. HKParts is definitely 2 thumbs up.


"Outstanding muzzle device for PTR91"

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

Comments and Suggestions: 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

Comments and Suggestions: Good product. It was a good choice to help manage recoil on the wife's PTR91. This muzzle brake and a Limb Saver recoil pad for the M4 stock were a good combination. Be advised the rifle is noticeably louder. The instructions could have been more helpful. The cupped side of the crush washer faces the base of muzzle brake. I had to call PWS to find this out after finding conflicting information on the internet. That being said, they answered right away, transferred me to the right person and were... More details

Comments and Suggestions: I added this on my PTR91KF and it looks awesome. I was worried that it would look funny on the rifle but its really pleasing to the eyes. Installation was real simple with the supplied crush washer and real similar to adding one to an AR. It mounts solidly and times perfectly. I haven't had a chance to shoot it yet due to the recent ammo shortages of .308 win but I expect it will work without a hitch. Would recommend it! 2 thumbs up HK parts!

devin craig on 1/18/2013 12:30:39 PM

Comments and Suggestions: The only reason I am giving this a 4 is the amount of blow back you get while firing this. But other than that it works great

Comments and Suggestions: I have been running a pws break on my AR for the past two years and love it, so when I bought my PTR9F I knew I had to get the same break for it. It reduces recoil to the point you dont even know your shooting a .308. Love this muzzle device and would recommend it to any one with this style rifle.


"Amazing"

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

Stars Rating:


Comments and Suggestions: 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.

Comments and Suggestions: 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

Adam Williams on 10/7/2012 12:59:57 PM

Comments and Suggestions: As always, HK Parts over delivers in the order process and delivery time. The PSW is a solid compensator. It was easy to install and certainly reduced felt recoil by probably 30-40%. Based on reviews I was expecting an unpleasant blast of gas each shot but never noticed this as a concern. I noted this as a 4 star rating simply due to the fact the washer doesn't tighten down and remains a little loose between the barrel and compensator. This doesn't affect operation simply not perfect on my PTR91... More details

Comments and Suggestions: 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.

"mixed feelings"

erik on 5/11/2012 12:38:32 PM

Stars Rating:


Comments and Suggestions: First off let me say that this is a very well made peice and install was a breeze. There is noticable reduction in muzzle climb and somewhat less recoil. It looks mean on the end of the barrel but the real bite is from the muzzle blast. Feels like a small nuke being detonated in front of you. It almost negates the recoil and rise benefits. If you can live with the blast- it does what it claims.

Comments and Suggestions: 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.

Comments and Suggestions: Taming the recoil was what I was after. I had already installed the HD buffer, and the difference was very noticeable. Adam suggested this also. Glad to report that the combo of the two has reduced recoil by 50-60%(at least!!!), depending on your ammo. Muzzle flash & sound was diminished greatly, too. Way to go Adam, you were right again!

Comments and Suggestions: 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.
