JR carbine jamming every 1-3 shots

[Riven]

What are you shooting ? 115, 124 ,147? I was told to stay away from 147!

Exactly what i was thinking. My beretta will not run on 180gr. Everything else runs 100%

My friend's is doing the same thing. We tried shortening the buffer spring (JR's request) and now they are sending a shipping label so he can send it back to them. Their claim was "we have never heard of this problem before" lol. Is yours .45 ACP?

hes shipping the rifle back to new york state from somewhere in Canada?

My JR ( 9mm )was never trouble free, the dealer exchanged it for the same and it was never trouble free, that was the end of my experience with the JR, sold it explaining there was some malfunctions, did adjusted the price down and told the truth, i got a Beretta CX4 NR and never look back after that, maybe i was unlucky with those... 2 times in a row.... My 0.02... JP.

i run mine clean and very very dripping wet, runs fine ever since ive been doing that.

Had a 9mm,.worked fine for 500 rounds.....after that couldn't get it to run right. And ya, run it wet. Wont buy another.

My 9mm has been flawless in 1200 rounds...............and it's run with very little lube. Obviously some people have had some less reliability. I will note that its a newer version with the round barrel and the holes instead of slots in the forearm.

This ^. Some firearms just need lots of lube for the bolt to travel freely. I've read that the newer ones are a little more reliable.
