Catalyst Arms Introduces A True Precision Rifle Handguard For AR-15 and Ruger Precision Rifles

Beaverton, OR – Catalyst Arms, LLC, a firearms accessory company, has introduced Fast Track™, a true precision rifle handguard for AR-15s and the Ruger Precision Rifle.  Designed for precision rifle competitors and long-range shooters, Fast Track™ has the features they have asked for in a handguard such as an integrated Arca Swiss style rail, flat sides and bottom, a smooth top for greater scope clearance, M-LOK® slots and ease of installation.

Fast Track™ has a full-length Arca Swiss style rail the full length of the bottom of the handguard.  This provides maximum versatility for mounting directly to tripods or attaching accessories that can be quickly moved forward or backward as the shooting situation requires.  The flat sides and bottom make the Fast Track™ much more stable than round handguards when shooting from bags, barricades, packs or other surfaces. A low-profile top provides maximum scope clearance for mounting optics as close to the bore as possible.  M-LOK® slots run the length of the handguard at the 3, 6 and 9 o’clock positions for mounting other rails or accessories. For ease of installation Fast Track™ attaches to both AR-15s and Ruger Precision Rifles via a two barrel nut system that is easy to align and torque to proper specification.  


Machined from 6061-T6 aluminum and hard coat anodized black, the Fast Track™ is lightweight and has a slim profile that is easy to hold when necessary and maneuver into shooting position.  The Catalyst Arms Fast Track™ is available for shipment February 1, 2019 with an MSRP of $219.00.

Ruger PC Carbine Add-Ons: The Catalyst Arms Hardpoint Kit


by Kevin Creighton

Ruger's PC Carbine has been a resounding success because of its ability to handle larger-capacity magazines, easy controls and compact size. It’s accurate, fun to shoot and very viable option for self-protection. The styling of the gun is based somewhat on Ruger’s previous 9 mm carbine, the Ruger Police Carbine of the late 90s and early 2000s. However, the state-of-the-art in gun accessories has advanced a bit since that gun was released, with innovations like quick-detach slings and rail-mounted accessories which allow you to tailor a gun to your exact needs. Lights, lasers and bipods are just a few of the common add-ons to a modern fighting carbine, and they can greatly expand the utility and ease of use of your gun.

The 2018 Ruger PC Carbine offers a section of Picatinny-compatible rail at the front of the stock, right in front of the sling swivel, as well as a rail on top of the receiver to mount optics and other accessories. That single section of rail up front is one of the few limitations of the PC Carbine. While it’s great for mounting a single mounting point for a light or laser, space quickly runs out if you want to add more than one accessory, and that’s where the Ruger PC Carbine Hardpoint kit from Catalyst Arms can help.


Each kit consists of a short length of lightweight, anodized aluminum that slides onto the existing rail at the front of a Ruger PC Carbine and a spacer that fits in between the rear of the stock, equipped holes on both sides to attach a QD (quick detach) sling mount. The front section is a nifty little device that offers not only three short sections of M-Lok-compatible rail slots but a reversible QD sling mount as well. Installation of the front accessory rail is easy: The QD mount is attached to a bolt that locks into the pre-existing rail, and it’s reversible for left-handed shooters like myself. Installation of the rear spacer requires the use of the hex key that comes with the PC Carbine (which, if you’ve lost yours, or decided to install this kit at the range like I did, is a 9/64-inch key).


Once everything attached, the Hardpoint kit greatly expands your accessory options. With three M-Lok rails up front, you can add shorter lengths of  M-Lok to attach lights, lasers or other accessories right where you want them, not just on the bottom of your gun,and a QD mount lets you add a newer style sling like the Vickers sling or similar sling. The spacer in the back didn’t affect my grip or sight picture on my gun, however, if you find it a bit uncomfortable,  you might want to look at the TacCom Competition Buttplate or a similar, thinner pad for the end of your gun that will reduce its stock length.


If you’re looking to do more with your Ruger PC Carbine, look into the Hardpoint kit from Catalyst Arms. With an MSRP of $89.95, it opens up a world of possibilities for one of America’s most-versatile guns.

New Mounting System for Ruger PC Carbine from Catalyst Arms

By Mon Berenguer

Whenever Ruger makes a new rifle, you can bet there will be a slew of innovative companies lined up to create a dizzying and impressive array of aftermarket accessories. This is true for Ruger’s famous 10/22, and it also applies to the new Ruger PC-9 Carbine. Established in 2017 by Kevin Haight and Matt Foster, Catalyst Arms LLC remains a small aftermarket accessories manufacturer based in Portland, Oregon, and just released their Hardpoint Mounting System for the Ruger PC-9 Carbine. This mounting system is a two-piece set, consisting of an M-LOK adapter that attaches to the PC-9’s accessory rail under the barrel, and of a quick-install buttstock basepad with QD sling mounts on either side. What the M-LOK adapter simply and easily does is attach to the single accessory rail under the barrel, and multiplies the PC-9’s accessory attachment capability threefold. Meanwhile, the basepad enables the rifle to easily attach a sling on the QD mounts for use by left or right-handed shooters.

The first of two components that comprise Catalyst Arms’
Hardpoint Mounting System is the M-LOK adapter.
When attached to the lone underbarrel rail, the PC-9’s
accessorization capacity is increased threefold.
Note that the three rail slots are sold separately

The second component is the basepad. Note the peg where the QD sling mount attaches

Given the hundreds, if not thousands of different lights, lasers, bipods and other accessories available, no doubt PC-9 owners will give their rifles more functionality and a more tacti-cool appearance. Proudly made in the USA, Catalyst Arms’ Hardpoint Mounting System is machined from 6061-T6 Aluminum and retails for $89.95. So if you owned a Ruger PC-9 Carbine, would you buy this system and what manner of add-ons will you attach?

The Ruger PC-9 (shown here with a suppressor attached) was featured in this year’s SHOT Show. Catalyst Arms, a small firearms accessories manufacturer in Portland, wasted no time
in making a Hardpoint Mounting System to allow PC-9 owners to sling and assist in “tricking out” the rifle

NEW HARPOINT™ Accessory Mounting System for Ruger PC Carbine


New Hardpoint™ Accessory Mounting System for Ruger PC Carbine

Beaverton, OR – Catalyst Arms, LLC, a firearms accessory company, has introduced the Hardpoint™ Accessory Mounting System for the Ruger PC Carbine. The newly developed system consists of a forend rail extension and front and rear push button QD sling mounts. Hardpoint™ lets Ruger PC Carbine owners attach multiple accessories and use push button QD slings for better rifle carrying and handling.

The Hardpoint™ attaches to the PC Carbine’s forend Picatinny rail providing three M-LOK® slots at the 3, 6 and 9 o’clock positions as well as an ambidextrous push button QD sling mounting point. The slots are located for greater accessory clearance than the factory rail. This gives Ruger PC Carbine owners more options for the size and type of light that will fit, as well as the option of mounting more than one accessory at a time without interfering with the sling. The system includes a butt stock length-of-pull spacer with an integral push button QD sling mount as well.

Gear Review: Catalyst Arms Mag Release Extension for Ruger Precision Rifle


By Louis K. Bonham

Since its introduction two years ago, the Ruger Precision Rifle turned the market for long-range precision rifles on its ear. For a street price of about a grand — less than half of what comparable rifles were going for at the time — you could get an out-of-the-box sub-MOA tack-driver.

What was equally revolutionary was that the RPR was a user-friendly platform that could be customized and improved as easily as an AR. Indeed, easily available AR grips, stocks, safeties, and some other parts can be swapped out to customize your RPR to meet your needs.

As aftermarket manufacturers tend to do when a popular new gun hits the market, many responded with RPR-specific items like trigger packs, barrels, handguards, and other custom bling for tricking out your Precision Rifle.

One of those areas of opportunity: the RPR’s magazine release. While there is nothing wrong per se with the RPR’s stock tab-style mag release, it’s not as ergonomic or convenient as it could be. The first wave in this area was a number of 3D-printed plastic Thingverse creations, which demonstrated that improvements to the mag release were indeed very doable.

The latest addition to this field is the Catalyst Arms Mag Release Extension for the RPR. Rather than being molded from plastic, it’s machined from 6061-T6 aluminum, with all corners and edges nicely relieved and then hard-coat anodized. Installation is a snap — the stock mag release fits snugly into a machined slot in the back of the Catalyst Arms extension, and a small machine screw (with a drop of Loctite for good measure) holds it in place.


When installed, it’s the same width as the magwell, fully ambidextrous and very solid. The mag release extension definitely improves the ergonomics of the RPR, allowing you to drop a mag without changing your grip. And it’s much easier to use than the stock mag release if you’re wearing gloves.

Specifications: Catalyst Arms RPR Mag Release

Material: Machined 6061-T6 aluminum
Colors: Black, Red, Coyote
Price: $29.95

Rating: (out of five stars)

Overall: * * * *
Nicely thought out and implemented, and works as advertised. I wouldn’t be surprised if, like other aftermarket RPR options, Ruger doesn’t adopt a design similar to this on future models.
