I am a lefty to naturally I want to take advantage of the ambidextrous fetures of the JR carbine. I purchased an AR amorers wrench for the castle nut (Doesnt work for the forend locking ring btw). I was advised by the fella at the shop that each rifle has a set torgue rating, and if over torqued it could damage/ruin the rifle, I am assuming that this could be for the castle nut as well as the take down screws.

Would appreciate it if someone can enlighten me a bit on the torque requirements and settings ... is this for both the take down screws and the castle nut or just one of these ? I have searched high and low for info to no avail.

Thanks in advance
 
Well, I don't know the JR carbine, but I've worked on enough machinery to figure it out if I was in your position.

I imagine the gun has a lot of aluminum, and that's the key point here. If no one chimes in with specific information, what you need to know is that Alum' is easy to strip, so it is very important not to over tighten.

Basically, snug it up, till you feel confident that it's not going to move. You're going for "hand tight", not sure how better to describe it, if you have to use strength, you're probably getting too tight.

It can sometime require experimenting. You'd have to go with your instincts, and then monitor for movement. If you detect any movement, go a little tighter new time. |

So yeah, don't know the JR, but hope these tips help if you can't find any other answers.
 
I own a JR, and Conte is right on the money. Hand tight, just enough to stop them from coming off. Hell, bring a tool kit to the range, if anything loosens up, tighten it with a bit more authority. If you watch the JR takedown video (look on their site), he doesn't mention torque settings. As far as the castle nut, You can tighten it up very snug.
 
As Conte said and I go one further by putting a dab of blue-loctite on to ensure they won't come loose from vibration.
The bolt-handle bolt is the biggest culprit for shooting loose (this one has a spring washer as well).
