Check for a bur on the gas relief spring in the barrel. Both my 18" and 24" barrels scratched the crap out of the tube. I took a grinder to it and fixed the problem. If you want to have some real fun, take the spring out of the barrel! That's not really that much fun, but putting it back in is a blast!!! Hmmm... tempted to send it to Mossberg. This is caused by the spring assembly in the barrell not being centered perfectly. If the gun is hard to reassemble this is the likely cause. I used a large deep socket to center mine. I polished up the scratched and its fine. Assembly is now much easier.

Hi all: Just double checking. does the fs slide fit the f? I'm looking to update the sights and still run tac optics. Thanks.

Hello All: I just reread all the posts about the JMPro. I've got a 22' 8+1 I want to try to use Nordic Components Mondo Extendo mag that will give me 13+1. I have it and have installed it but have issues with tuning. I was talking with Nordic Components and he recommends replacement of the shell stop spring, the lifter spring and polishing of the shell catch. I was going to do the polishing but I may as well replace the springs if I'm in there. So, where do I get replacement springs? Would stock mossberg parts be best or is there an aftermarket company that someone has used and recommends? The Nordic components extended mag should get me 13+1. If I load 13 it won't cycle by hand and the last shell is very hard to load. I do have the Nordic follower. Can this be to much spring pressure on the shell stop? Would polishing the shell stop help this? Tuning the spring has been a chore any tips or tricks would be helpful. Stock the JMpro runs great, It will cycle anything now that I've had more than 500 shells and slugs through it, and clean and lube it properly. I would like to see if the extra load capacity makes a difference in times during stages but am reluctant to try the mondo extendo mag with out being able to cycle by hand. An equipment fault is something I really want to avoid. I would love to hear your thoughts and suggestions. No I'm not getting another shotty, I love my JMpro.

Nice! With the 28 and a new Nordic tube the jm should hold 13. Not bad.

T I'm a member. The first rule about sharpshooters is you don't talk about it. Lol. Mondays I will keep that in mind. Y'all got any uppers in stock?

For any one that has a jm pro is the mag follower orange or just plain steel? I was reading a thread that said that. Mine is just steel. BTW I love the darn thing. Its more fun and cheaper to shoot than my stag 3G.

I'm sure I'm not ruinning the gun wet enough. It happend only once last weekend. I sprayed the bolt with CLP and it didn't happen again. I'm now oiling and using cLP. I will mess around in a week or so and give an update. I've not loaded my pmags fully as that is a shit ton of money. Luckily ammo prices are coming back to reasonable levels and I can even afford more pmags now. (that was not a political statement, just fact)

I haven't shot a three gun match but I'm prepared. I got it all. Including a 22' JM pro. I've been reading all the shotgun threads because I see that the shotgun can be the make it break or it weapon for most matches. I've seen three matches and it's plain to see that the guys that have the shotgun loading down do better. My question is, is barrel length that important and why? I love my shorty JM Pro. I've been shooting trap and skeet with it for practice. I can hit flying birds pretty far out there with full choke with the 22' barrel. I got a 28' ported barrel so it's better for long distance trap and skeet. I also orderd up a new Nordic tube that will give me 13+1 with the 28'. If I understand the rules for tac optics I can start with 8+1 load as many as I can and start the stage as long as the ports are covered. I've read the threads on how to do this. It seems like the trend is moving towards longer barrels. I also don't understand why a ported barel would move you to open. With a shotty how much difference could ports make? Is it that much of an advantage? In short what is the difference between a short barrel and a longer one for three gun? Can 6' really be that different?

It happened once last weekend. Tried several mags. I think my rifle may not be wet enough. In just usin CLP.

I got the voodoo tactical 3gun 46 inch bag. Fits my mossberg jm pro 22 and my stag 3G just fine. Nice quality.

And the problems are what??

I've been tracking ammo .223/5.56 daily and I do see a downward trend on price. I hope it keeps up. I'm still sure my Stag 3G is worth more than I paid, that said I'm not selling. I want to shoot. Nice info.

Thank goodness it's over.

Sounds good I'll do it. At current ammo cost I'll suffer the failure durring a match though as I'm a newb. I can only get better.

Good point. I've tried to make sure that doesn't happen. I'll figure it out. I'm still thinking operator error is the cause.
