MAJOR DEFECT DISCOVERED in my barrel: J&J Owners Please Read

[new_Faction64]

***PLEASE NOTE: THIS IS NOT A DEFECT WITH THE MR2 MARKER ITSELF***

Hi everyone, as long as I've had my MR2, I've used my J&J Performance Ceramic 12" Barrel. I've also been having bad chopping problems, replaced the detent, and broke in the ACS bolt.

I'm glad but also disapointed to announce that I have discovered my problem: The J&J barrel. Apparently the barrel is not long enough to screw far enough into the MR2, nor my Spyder TL-R, to close the gap with the internal tube of the markers. Basically, there is a gap between the internal tube and my J&J Ceramic barrel, it was a pretty large gap too. May be this big: ||

I'm fairly sure this is the reason for my chopping, and along with RMAing my barrel, I wanted to notify all MR2 owners, since I know that many, many owners have J&J barrels. PLEASE CHECK YOUR BARRELS!! Remove the feedneck (w/ the three screws) and stick a finger down the tube, please do this w/ air source removed and marker off

That's basically it guys, I wanted everyone to be aware of this problem I had, so anyone else with a J&J barrel can check theirs and make sure they don't have the same problem as mine.

that stinks man... You may have gotten a dud. I have a J&J S2 and it works great on my Rodeo. Fits tight and I have no breaks with it.

Yeah I know these barrels are extremely popular, and it's a real bummer knowing I got a bad one.

Well I use J&J barrel ( older version ) I have no problems at all with the barrel or the marker

Make sure your O-ring is in the right groove. I noticed that it has two grooves on mine. Either one can hold the O-ring, but if you use the groove closer to the threads, the O-ring ends up hitting the threads as you screw in the barrel. I made that mistake with mine and broke the O-ring. I put a new one on the other groove and it screws in all the way and meets the body firm.

I even tried taking the o-ring off, exact same results/problem.

Strange indeed. Mine fits good, maybe you did get a defective barrel. Bummer bro. I have an Apex on the way. Don't think it will fit through the shroud, but I think it will be worth it.

I think they do fit I'm not sure though because everyone that said they use Apex barrels don't say if they have the shroud on or off

[Msniper]

yeah mine is ok!

There's a picture on pbreview.com w/ the MR2 w/ Apex WITH shroud on. It works.
