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.
