So awhile ago I bought a JR carbine in .45 acp
I had done quite a bit of reading and found that the 9mm was very reliable however the .45 was problematic.
I bought the .45 anyhow cause that's how I roll. besides I've fixed lots of guns, how hard could it be?
So first trip to the range proved all those internetz people right. FTF city! (insert emote here if that's your thing) 10 shots at 25 meters using my elbows as a rest was one ragged little hole however!
folks at JRC blame glock mags cuz we all know how unreliable glocks are. Twist your spring like this and that blah blah.
I did notice that the glock mag puts a whole bunch of pressure at the front of the follower and not so much at the back.
Many of the FTF cases had been punctured by the nub that protrudes from the bottom of the bolt damaging my cases beyond reloadability. (spellcheck sez that aint a word but I think its wrong)
tried both factory ball and my reloads, same same.
In conversation with folks at JRC they have a reliability package that they want to send me. this consists of a new mag well with a different feed ramp bolted in. Also a new buffer and a thicker nylon disk.
so a package arrives in the mail but I'm fighting a losing battle with a win 94 in .357 I bought to console myself with.
A couple days ago I put the new parts on. The new feed ramp is more robust and the mag well holds the magazine tighter and maybe has the rounds more aligned to the bore.
To the Range today, what a gong show! I got my truck stuck, I cut my hand shoveling the snow from the range, left the red dot on from last time I used it and the battery is dead, forgot my brass catcher and wore runners instead of boots.
However, the factory glock mag fed flawless! the 27 round aftermarket mag less than that but the spring is pretty weak for the top ten rounds compared to the glocks.
my group opened up a bit to 18 inches without having the little red dot in the optical sight. have to do something about that.
