Rise above the competition with the TANDEMKROSS UPRISER Chassis for the Ruger® PC Carbine® and PC Charger™!
The lightweight reinforced polymer UPRISER chassis is both lightweight and durable while providing a better balance and feel.
Designed with cross-compatibility in mind, the UPRISER Chassis will accommodate virtually all AR grips (with or without “beavertail”) and mil-spec buffer tubes and stocks or braces!
The UPRISER package includes:
- Extended magazine release
- Flared magwell (hardware included)
- "hiveGrip" for AR-15 (hardware included)
- Stock and grip adapter
Trigger finger extended mag release:
Don’t skip a beat! The unique trigger finger actuated magazine release allows for quick and intuitive magazine release. Simply lift your finger off the trigger and press the release for fast and reliable mag changes.
Flared magwell:
The wide, flared, and beveled design guides the magazine directly into your magwell for faster and consistent mag changes.
hiveGrip for AR-15:
Defined, ergonomic finger grooves improve hand placement for more accurate, controlled shooting while the slim, low-profile design ensures an ideal fit for any user. Made from patented impact- and vibration-dampening material, these hiveGrips are an ideal upgrade for any AR-15. Designed with a hollow grip, the hiveGrip for AR-15 includes a removable O-ring sealed bottom to provide water resistant storage space for tools, extra rounds, or survival items.
Angled Stock and grip adapter: The angled Stock and Grip Adapter is angled at a 12° downward pitch. This is a perfect choice for iron sights or low-mounted optics. When shouldering the rifle, the stocks downward angle brings the sight picture up to your face allowing optics to be mounted closer to the bore axis. This also creates a comfortable and ergonomic cheek weld for quick and natural target acquisition.
Straight Stock and grip adapter: The straight Stock and Grip Adapter matches the more traditional aesthetics and ergonomics of the AR-style buffer tube and buttstock. This is great for anyone looking to use their Ruger® PC Carbine™ or PC Charger™ as a trainer. This is also ideal for anyone who prefers to mount their optics on a riser or who needs their optic mounted higher to allow for use with lasers, IR lights, thermals, or nods.
Don't be left behind! Elevate your performance with the new TANDEMKROSS UPRISER Chassis!

Upriser
I've waited to write a review until I could be totally objective. I waited with anticipation for delivery of my Upriser chassis. Once again the shipping time from Tandemkross did not disappoint. I had just finished shooting a USPSA and my delivery was on the front porch. When I opened the package I was very impressed with the way all the parts were laid out in the box. I didn't even take the time to get out of my jersey before I began to install the pieces onto my PC carbine. I found the online instructions very easy to follow and in no time I was looking at my Upriser equipped Ruger. Since then I have shot several Steel Challenge and USPSA Matches and have been very impressed. The angle of the stock raised some eyebrows of several very good PCC shooters, but after allowing them to shoulder the weapon they see that it's a great fit. With the C-More Railway and the angle of the stock the optic is exactly in line with my eye when bringing the gun onto a target. Having the availability of a left side and right side mag release allows me to shoot both strong hand and weak hand with ease. The right side mag release is large and is easy to reach with the trigger finger for quick magazine changes. The addition of the extended magwell also makes mag changes quick and easy. I would highly recommend the Upriser chassis to anyone wanting to utilize the Ruger platform for competition as well as everyday target shooting. The folks at Tandemkross never fail to impress with quality innovations. Many thanks for all you do.

Upriser Chassis
Exactly as described and works as described. The angle for buffer tube is perfect for fast sight/target acquisition. Since my preferred LOP is longer than most, tried using a rifle length buffer tube vice carbine. Cannot tighten down as threads hit chassis before fully tight. Could be solved with a custom washer. If I had more than one Ruger PCC, I would buy again.

Tandemkross Upriser
The Tandemkross Upriser chassis for the Ruger PC carbine is a terrific upgrade to an already great little carbine. As expected based upon previous experience with upgrades from TK everything fit perfectly and the installation instruction were clear and concise. The angled butt stock is a real improvement making the site line and site acquisition very easy and fast. The competition style mag release and mag well are a nice touch as well. Great pricing and delivery from TK as always. I highly recommend this upgrade.

Awsome Addition but one Flaw leftys
With all the chassis upgrades for the Ruger PC Carbine, the Uprisers checks a lot of boxes. It's way cheaper then all of it's competition. It allows uses of factory sights or low mounted red dots. Lastly, it speeds up mag changes by bring the mag release button close to your finger, however the one flaw is in that feature for. It totally makes this chassis useless for left handed shooters. As a lefty myself, I would find this chassis slower in mag changes because I have to bring my support hand back further then just having the button on the right side of the mag well. For right handed shooters, this may be the best and cheapest AR chassis conversion on the market.
