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
(CatalystArms.com/shop/ruger-pc-carbine-hardpoint-kit).

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
