I saw the QC-5 MP-5 magazine AR at SHOT Show 2017, and have been stalking Quarter Circle 10 ever since waiting on this. Why MP-5 magazines? Because they are very good 31 round magazines, perhaps the best SMG magazines in the world, because they are available and because many of us have MP clones and already have a ton of magazines.
Quarter Circle 10 says receivers are currently coming off the machines. The QC-5 will be available for purchase, as a receiver set and as a complete firearm Summer 2017!
The QC-5 Features a version of Quarter Circle 10’s new, non-reciprocating side-charging upper receiver. The standard version of the Side-Charger will also be available this summer, so you can finally convert your GSF, GLF, or CLT9MM to a side-charging manual of arms.
