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!

Upriser Chassis for Ruger PC Carbine
I just purchased one of these upriser chassis for my new PC Carbine. Fit & finish is very good and it is quite light as compared to other aluminum versions on the market. Ease of installation was a no brainer with TandemKross's excellent tutorial videos. I've had 2 minor issues with it so far (haven't been out shooting with it since this upgrade). 1... The mag release bar was sticking, due to the socket head cap screw they provided, was sliding past the stop point it was supposed to land on and friction sticking down. An easy fix with a larger headed screw (I actually turned a few thou off the screw with my lathe, to fix the issue). 2... When screwing in the buffer tube, it's quite easy to screw in too far and cause a gap to appear between the stock/grip adapter and the upriser chassis. This is not really a big deal, just unsightly on quality components like this. I noticed this in a couple of the YouTube videos as well. I tried repositioning everything tighter and then screwing in the buffer tube... but still pushed the slight (1mm) gap right back, when attempting to "bottom out" the tube and not have it lose prior to tightening the castle nut. Not sure what a good fix would be, other than a slight design change... may have to turn a thin Delrin ring to serve as a spacer in this gap. Other than these 2 very minor grips, very excellent product for the Ruger PC Carbine.

Uplifter Chassis
Overall great product and easy to assemble. Video provided is for the rifle stock carbine so installation was slightly different but nothing major. Happy with the upgrades, but the inclusion of buffer tube or ability to install a picitinny adapter would be nice feature for a folding stock option.

Upriser
This was so easy to put together. Looks good and shoots great.

Upriser chassis
I stared with the upriser then switched to the straight, it just fit me better. The only issue I've had is keeping the screw tight that holds the straight or angled adaptor in place. If I really tighten it, it binds the bolt assembly. If I back it off slightly, I have to take the grip off and snug it up after about 50 shots during Steel Challange matches. Other than that it's a great design and looks great

Great Product Great Company Great Service!
I purchased an array of items including the Upriser, Victory Trigger, Challenger charging handle, Shock Block and both the angled and straight grip adapters for my PC9 and of them have been great. The products are quality and really are easy to install. These have definitely increased my enjoyment of what used to be a stock firearm. However, the reason I wanted to write a review was that on my last order a smaller item I wanted was out of stock, so in the order notes I stated that if the part came in before the order ships, please add it to the order and I would pay the difference. Well, imagine my surprise when the order showed up at my door with the extra part included, for FREE! That's how you build customer loyalty and says a lot about the great folks there at Tandemkross. Thank you guys, I'll be back!

Upriser chasis is awesome
I absolutely love my upriser chasis. Easy to install good fit and finish. The ergonomics of the angled version are amazing. I paired with the utg pro fore end and it looks like they were made for each other. Tandemkross hit another homerun with this one.
