Primary Weapons Systems Releases Multiple New Product Lines at SHOT Show

Primary Weapons Systems released a number of new products at the recent SHOT Show. There is a lot to look forward to from PWS in 2018:

Primary Weapons Systems released multiple new product lines and updates at SHOT Show last month.

Starting with the MOD 1-M line (replacing the MK1 MOD 1-P line) with M-LOK handguards and Radian Raptor charging handles. Keeping the internals the same, the MK1 MOD 1-M line got a simple facelift. To match that, the MK2 MOD 1-M line also got M-LOK handguards and Radian Raptor charging handles.

Past the more expected updates, we take a look at the MK1 MOD 2-M line which replaces the MK1 MOD 2 line. The MK1 MOD 2-M line features not just an M-LOK handguard, but their patent pending PicLok handguard. Yes, it offers M-LOK along the entire length of the handguard, but also offers Picatinny in the front quarter of the rail. What sets the PWS MK1 MOD 2-M handguards apart, is the fact that M-LOK accessories direct thread into the handguard, meaning you don’t use the back T-nut of the accessory. This allows the shooter’s rail to truly stay as slim as possible while still offering a variety of mounting options. In addition to the PicLok handguard, the MK1 MOD 2-M line includes the Radian Raptor charging handle and Radian Talon safety selector.

For PWS customers wanting to do a quick handguard swap, we have good news! Handguards will be available as standalone items, so you can easily swap your current PicMod to PicLok.

The ALPHA line of rifles, easily differentiated by the FDE anodizing, was designed specifically for military use, but will be available for civilians. A few features of the ALPHA line are the heavier barrel profile, 1:7 barrel twist rate and gas adjustment knob in front of the handguard.

The last big release from PWS was the new PCC line in 9mm. Using a straight blowback system, taking GLOCK mags and having last round bolt hold open, PWS expects the PCC line to be a popular addition to their current offerings.

The PWS website is currently being rebuilt, but will be live by mid-February. In the meantime, customers can contact sales@primaryweapons.com for questions and purchasing.

Company Information:

Primary Weapons Systems (PWS) was formed in 2008 as a rifle component company and has since grown to be one of the largest firearms manufacturers in the Northwest. PWS initially made firearm accessories and compensators, but quickly moved into firearm manufacturing as they developed their PWS Long-Stroke Piston System which takes the operating system from Kalashnikov’s AK design and merges it with Stoner’s AR platform giving a hybrid rifle to shooters looking for a low-maintenance yet reliable and accurate firearm. PWS manufactures AR-15s in 223 Wylde, 300BLK and 7.62×39 as well as DPMS .308 pattern builds in both .308 Match and 6.5 Creedmoor- all with the long-stroke piston operating system. The PCC line of 9mm products is the only line that varies from the piston system, being a straight blowback system. Also manufactured by Primary Weapons Systems are lightweight buffer tubes, steel body buffers, accessories and a wide selection of compensators for firearms both piston driven and direct impingement.




Primary Weapons System’s (PWS) new FSC MOD 2 has some big shoes to fill. The FSC series of muzzle devices with the FSC556 in particular, are iconic for their dead-level muzzle control and sufficient flash suppression. They were some of the earliest of the so called hybrid muzzle devices and they remain some of the best in terms of performance.

The new FSC MOD 2 appears to have a very similar design for the device’s side ports but the flash suppression prongs have been done away with in favor of a closed end with slots. As long as the FSC muzzle devices continue to offer the neutral muzzle control that made shooters fall in love with them, this new version will be a hit.

Check out the FSC Series page at PWS. As of the time of this writing, all previous generation FSC devices are shown out of stock and the FSC MOD 2 is not yet listed.

PWS Launches Online Store

Primary Weapons Systems (PWS) has launched an online store and redesigned their entire website. That means you can now purchase PWS’s muzzle devices, complete uppers, barrels, hand guards and more direct from the source.

Check out the new PWS website and online store.


PWS DI Uppers

PWS is well known for their piston AR-15s. Now they are throwing their hat into the direct impingement (DI) ring.


Their DI uppers share many of the same features with their piston uppers like extended length KeyMod rails, QPQ (nitriding) processed barrels, and they are topped off with one of PWS’ great muzzle devices. The barrels have a 1 in 8″ twist and they feature a .223 Wylde chamber which should help a bit with accuracy while also handling 5.56 spec ammo.

The MAP for these uppers is $699 which isn’t bad considering what you get. That is especially true for the 14.5″ version since pinning and welding a muzzle device usually costs extra.

Check out the new DI uppers at PWS.

All PWS AR Pistols Shipping with SB-15

PWS is now including an SB-15 Pistol Stabilizing Brace with all their AR Pistols with no price increase! How cool is that?

Review: PWS Triad

In the time that it takes you to read this sentence, 10 new AR-15 muzzle brakes/compensators will have come to market. That may be a slight exaggeration, but there is certainly no shortage of options currently available with new ones coming frequently.

The PWS Triad is one of the more unique devices to come down the pike in recent history. It lacks the multitude of small holes or large side ports of most devices that claim to help control muzzle rise. In fact, it looks like a fairly run of the mill 3 prong flash suppressor. So, can a device that looks like a flash suppressor perform like a compensator? Read on.

PWA Triad


The Triad isn’t a compensator or muzzle brake. It is a flash suppressor that helps control muzzle rise. Most hybrid devices (devices that both suppress flash and muzzle rise) tend more toward a muzzle brake in terms of design and function. The Triad is more like a flash suppressor in terms of design and function.

The flash suppression is accomplished via 3 large prongs not unlike other flash suppressors on the market. The muzzle rise reduction is accomplished by extending the slot between the prongs at 1:30 position (from the shooter’s point of view) back a bit further. I am sure there is also some internal shaping/magic that also helps.

Observations from Use

There are really two ways to judge the Triad. You can judge it on its flash suppression and on how it reduces muzzle rise.  I will address each separately.

The Triad is a good flash suppressor. It is not quite as effective as the best flash suppressors on the market, but, remember, it has an additional trick up its sleeve. I would say in my limited dusk testing, that it suppresses flash better than an A2 on a 16” barrel. It is a bit better performing than something like a YHM Phantom. It sounds like I am downplaying its performance as a flash suppressor but that is actually quite good – better than any other hybrid device that I have tried. I should also note that it doesn’t ring/ping like some pronged flash suppressors.


Your impressions of how effective the Triad is at controlling the muzzle will likely vary depending on your skill level as a shooter. Those who do an excellent job of controlling the muzzle rise of an AR-15 through their use of grip and stance will find that the Triad may actually force the muzzle down a bit. It seems that devices attempt to steady the muzzle one of two ways – they either try to trap the muzzle in space (by venting gases out both sides or fairly evenly around the device) or vent gases up to force the muzzle down. The Triad is definitely in the later camp.

I actually liked it quite a bit. While it doesn’t keep the muzzle as steady as something like a PWS FSC556 would, it does offer an extra degree of control without any real additional sound or overpressure… or at least none that was noticeable to the shooter or those beside the shooter. That is the real story here. PWS has managed to create a device that helps control the muzzle without all the negative side effects. That alone makes this a noteworthy device to me.

Wrap Up

The Triad isn’t the best performing flash suppressor. It isn’t the best performing compensator (it isn’t really even a compensator at all). However, it is one of the best functional combinations of the two that I have used. This is an impressive device in terms of its all-round performance. If you are looking for a device that offers some muzzle control, but flash suppression and over-pressure/concussive blast are a concern for you, the Triad should be on your list of devices to try.

I got my PWS Triad from Brownells.com.
