Rise above the competition with the TANDEMKROSS UPRISER Chassis for the Ruger® PC Carbine®!
The lightweight reinforced polymer UPRISER chassis reduces the overall weight and provides 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/stocks!
The UPRISER package includes:
- Extended magazine release
- Flared magwell (hardware included)
- "hiveGrip" for AR-15 (hardware included)
- Stock and grip adapter
- Dowel pin
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.
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.
*Stock and Grip adapter available in two options:
(Option #1)Angled Stock and grip adapter: The Stock and Grip Adapter is angled at a 12 degree pitch. This is a perfect choice for red dot optics as the design allows for use of a wider assortment of sights. When shouldering the rifle, the sight picture is closer to the bore axis which allows use of an RMR, scope, or red dot without a riser. This creates a comfortable and ergonomic cheek weld, which will result in quick and natural sight acquisition.
(Option #2) Straight Stock and grip adapter: The Stock and Grip Adapter match the more traditional aesthetics of the AR style Buttstock
Don't be left behind! Elevate your performance with the new TANDEMKROSS “UPRISER” Chassis!

Really good with one nitpick
Overall, the whole system is pretty good and I would recommend it. However, there's a significant nitpick. (But can be solved) If you buy the chassis with a grip, there's a good chance that the chassis walls will not run flush against the sides of the included grip. That creates a sharp chassis wall section that actually hurts when your hand rubs up against it. I relayed this concern to CS and they said that it was designed that way to be compatible with the most third party grips. This proved true as when I put on a thicker aftermarket grip, the width of it ran flush with the chassis and the issue of the sharp edge was completely gone. CS completely helped me out and allowed me to return just the grip for a refund. (Awesome CS support) So, I would still recommend the system but not with an included grip. Get a wider topped custom grip. (I got an Ergogrip.) Also, don't use the Titan magazine release with the chassis as it sticks out too far and won't sit right in the chassis. That section has been narrowed to make the stock release button easier to use. Customer Support was most excellent and helped me out with no fuss. They deserve credit otherwise I might have returned the whole thing because of the bad grip interaction.

Upriser
Awesome product!! For those of you running a Volquartsen trigger on the PC9 you will need to check the fit up at the stock adapter very close. Once I clearanced that, all prefect!!

Upriser Chassis
I bought the straight chassis for my 1PC Carbine Model 19115. The install video was easy to follow, and only took 25 minutes. Tech Support was also great. I had a question regarding my red dot mounting and how it lined up with the sights on the barrel. The tech was very helpful and knowledgeable. On the range the Chassis performed awesome along with the TK Challneger Charging Handle, and Game Changer Pro Compensator. It was Easy to change mags with the fluted mag well and trigger finger side mag release. Thank You, Scott

Good upgrade
The Upriser Chasis made my Ruger PCC handle so much better. At first I thought I'd want the straight model, but that was a mistake. Tandemkross' excellent customer service team swapped the straight adaptor for the angled one at no charge. Even shipped my replacement for free. Thanks guys! The angled setup is perfect and I can bring the rifle up to a perfect cheek weld quickly and repeatedly. The mag release lever does offer a very fast way to release magazines, but I'm still getting used to it being right where I rest my trigger finger when not engaging a target. I saw one review that stated the release system made the chassis unusable for lefties. I disagree. You can still operate the release button on the left of the chassis so it's really an ambidextrous solution. I train shooting both left and right handed and have not had a problem.

Best Chassis for the PCC
I absolutely love the look, feel and performance of this chassis. Quality design that sets the bar to another level. I am not trying to degrade midwest ind but this TandemKross chassis is the best stock for the Ruger PCC

Hot rod in a box
I bought a PC Carbine on a whim...I took it to the range and enjoyed it. Fun yet somewhat odd to sight and shoot. Thought I’d throw on a red dot and at least redo the trigger. These items made the gun better but it still was kind of generic to look at and the shooting angle was still meh..... Being a huge Tandemkross fan boy I eyed the Upriser angled mod but it was out of stock. Till one day I received an email telling me that the upgrade was now in stock....so I ordered it. In typical TK fashion it was shipped out quickly and There it was on my doorstep in a couple of days. Installation took minutes and the transformation was complete. Wow! From bland to bang in’! Instant hot rod! Like a Pc Carbine built by Ferrari. The shooting angle is now killer and every time I pull it out at the range, someone will ask what it is and want to inspect it. This is a 5 star upgrade but the only complaint is how the buffer attaches to the chassis. It’s seems a bit flimsy for really heavy use and would probably not hold up in a life or death bug out situation. Thankfully the chances of me having to defend my family in the situation I described is probably never going to happen. If you own a Pc Carbine or are considering purchasing a 9mm carbine...the Upriser upgrade is a must have.

Upriser
It took a little fitting to get it a perfect fit, but if your patient you will like the results. I used a Hogue over molded six position milspec collapsible butt stock with the kit and I am very happy with the overall quality, fit and functionality of the firearm now.
