JR Carbine Update
This issue has gotten worse the more rounds I put through it.
I got to speak to the JR Carbine team while I was at the NRA Convention. Joe, the lead armorer was very helpful and took a lot of time to discuss the issue. He agreed that the buffer spring was too tight.
The day after I got home from the convention a new spring arrived in the mail. No charge.
That is good customer service.
It seemed better, but it did jam once, with a different kind of failure.
I was not running it this time with the suppressor to ensure that is not a factor.
--It shot pretty good at 150 feet.
