I bought .40 cal AR-style carbine from JR Carbines this summer. I chose it because it uses Glock magazines, and I already had a Glock model 22 with a handful of spare mags. I also chose it because it could switched to left-handed ejection very easily, similar to the Beretta Cx4 Storm.
When I bought the gun I had to have a gunsmith switch it to left-handed ejection, including having him "break" the edge of the extractor so it extracts properly, per the instructions. My gunsmith did that, and even called the manufacturer, who sent me a left handed extractor in case the gunsmithed one didn't work.
I shot the gun, and after about 20 rounds, it kept failing to eject. The spent brass would flip around backwards and block the new round from going into the breech. I also found out that he bolt catch on the left side was too narrow for the bolt handle to fit into, so I couldn't lock the bolt open.
I sent the gun back to the manufacturer, and they replaced my receiver. I also had the left-handed extractor installed. When I got the gun back, it still failed to eject, in the same way, so I sent it back to get fixed.
I got the gun back with a new extractor and "high speed" bolt. There was no note, but when I called the manufacturer they said they test fired it for 30 rounds without a malfunction. I took it to the range, and after 70 rounds, it malfunctioned. Same failure to eject. But it was worse that time, I couldn't shoot more than 1 or two rounds before I had a failure.
Well, it's no fun having a gun that you can't even shoot for a half hour on the range, and I could never rely on it in a gunfight, so I sent it back to the manufacturer and received a full refund.
Bottom line, the gun wasn't any good. But JR Carbines gets an A for customer service. Based on my experience, I can't recommend their gun. But they were professional and courteous so no hard feelings. I hope they continue their R&D engineering and improve their product.
