PC Charger Stock: The Best JMac Rear for Your Charger

The best PC Charger stock in our lineup is the 1913 Rear Kit. Its SM-1913 mount fits the 2020 PC Charger, and the kit adds an SS-8RP SS® skeleton stock with a 0.275" built-in rise and rubber buttpad, plus a 3/4" cheek riser. The Charger's rear Picatinny rail is a mount point, not a finished rear, and these three parts finish it.

What goes on the PC Charger's rear rail?

Three parts, also sold together as the 1913 Rear Kit:

• SM-1913: a low, light, non-folding 1913 mount for JMac and SIG-style stocks. 7075-T6 aluminum, Type 3 hardcoat.
• SS-8RP-G skeleton stock: 8" long, 7075-T6, with a 0.275" built-in cheek rise and a permanently molded rubber buttpad. Its height adjusts, and it is drilled and tapped for risers.
• CRIM75: a 3/4" bolt-on cheek riser, 0.5 oz, hardware included.

Do I need a PC Charger stock adapter?

No separate adapter is needed. The Charger has an integrated rear Picatinny rail, and the SM-1913 mounts straight to it.

Why add a cheek riser to a PC Charger?

So your cheek meets the optic instead of your neck straining up to it. The SS-8RP already gives 0.275" of rise. The CRIM risers add 1/4", 1/2" or 3/4" on top of that. If you change optics often, the CRSU adjusts to three heights in one riser.

What if I want a different rear?

The same SM-1913 takes any JMac rear:

• ST-7R skeleton tube: 3.90 oz, height-adjustable, with QD sockets.
• TS-9P-G triangle: 9", rubber buttpad.
• SS-8RP-T, the tan skeleton stock.
• An arm bar setup with the AB-BS stabilizer. It rests on your forearm and works on hosts with a 1913 rear rail or a JMac RSA adapter.

Is there a PC Charger folding stock option?

The SM-1913 is fixed and does not fold. JMac's folding 1913 mechanism, FM-SM-1913, is a separate part. We have not confirmed its fit on the Charger and it was out of stock on 10/30, so contact us before ordering.

Which other guns have a factory 1913 rear?

The Ruger LC Carbine (.45 Auto and 10mm) also has a factory rear Picatinny rail, and the SM-1913 fits it. A PSA JAKL fitted with the 1913 rear end plate fits with conditions: the end plate creates the interface, so confirm your exact JAKL SKU and end plate.

The stocks and risers attach to the SM-1913 per the JMac catalog. Fit and availability are separate. This guide covers fit, not legal status. Check current federal, state and local law for your configuration.
