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!

Just awesome, almost
Everything about the upriser chassis seems to be well thought out and designed. I chose the angled version and again that was an awesome design. My only complaint is the stock. I like how its designed to use a regular AR stock. However, with the angled down version it puts the top corner of the stock into your shoulder. I think that as good as tandemkross is at designing awesome accessories, they could go the extra mile and design an adjustable stock that is angled so that the stock sits flat against your shoulder. In the meantime Missouri tactical makes a pad that is curved and thicker on the bottom and it fits perfect on the rim fire buttstock that tandemkross sales. It makes the butt stuck a little more comfortable on the shoulder. Would much rather tandemktoss design an angled adjustable butt stock to match perfectly with their chassis.

PC9 Stock kit
Can't say enough, this makes a sweet rifle absolutely awesome. Took maybe 15-20 minutes to install, another 15 or so for the Victory Trigger. Shoulders quite well, cheek weld spot on. Trigger is super smooth and lightening reset. Best mods so far with this rifle. PC 40 is next.

Upriser
I love it...a total transformation. Very comfortable to handle and shoot now. Its also a bit shorter arter i break it down so it stows in my pack better. Just what i needed. Thank you TK

UPRISER CHASSIS
I almost didn t purchase this chassis system due to the unconventional look of the angled buttstock. However I discovered that this design actually improves the already excellent erogonomics of the stock PC Carbine. Unlike AR platforms, I probably could now run my red dot with minimal bore offset. (but ammo is too damm expensive just to re zero my optic). I think recoil is even further mitigated vs the factory setup. Also, I have had zero problems with the install. My alpha count has gone up, and I am hoping to utilize my new UPRISER to get bumped up a class in USPSA. Many thanks to the forward thinking innovators at TANDEMKROSS. They have great customer service too!

Great mod, I should have stuck with the angled instead of the straight.
This is a great mod for the Ruger PC carbine. I bought the straight adapter instead of the angled and I regret it. With the straight adapter, you can't use the iron sights. Still, it's a great mod, easy to install and makes the carbine a lot more fun to shoot. After I purchased this mod, I ended up ordering more of the mods for this rifle. It definitely made a HUGE difference in performance and functionality.

Upriser Chassis
No-Brainer enhancement to PC9. Already ordering second “Upriser” for my wife’s PC9. Really improves feel, looks and functionality! Love the Butt-Stock!

Upriser - Great upgrade
I purchased the straight version and I'm very happy with it. I purchased it without the grip because I had a Hogue grip already on that I am fond of. The price was right. I used TK's email notification to let me know when it was in stock and had it ordered within 3 minutes of the notification! Very pleased with the setup.

Upriser
Seriously can’t beat the price for what you get. Other chassis’ on the market will run you more than twice this. Not to mention the compatibility with almost any grip or stock, solid win. The trigger finger mag release was also wayyyyy more functional and practical than I expected. For the money, there’s no other option. This thing is amazing

You may not necessarily NEED the upriser chassis for the PC carbine, but....what the fuck am I talking about? Of course you need the upriser chassis! This chassis, like the Tandemkross slogan suggests, makes a good gun great! Functional design + quality workmanship = one badass result. Go get it (or add your name to the wait list)
