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
