Rocking the JP Trigger. Absolutely love it.

This guy is a freaking alien

I really like both the Agula 124 and the American Eagle 124

filed down the inside of my glock mags and was able to get it loaded just fine. its an issue with the follower hanging up from when the mag transverses into the mag extension.

I wish 300 was not a big deal.

That is what happened. We tested mulitple uppers, bolts, rails, and etc. Even a MBX rail/bolt/upper that were provided by MBX.

Part of the test was using the ammo that MBX provided me to perform the test with.

I personally watched Mac-PCC shoot a .6" group with the barrel and scope. With my new JP rifle, shooting Blazer Brass, just propping the front of the rifle, I shot a .5" group at 25 yards.

I can not speak for the other guys. I bought this barrel due to the lightweight attributes of it and a recommendation from someone else. The other 2 purchasers of these barrels I do not know, until now. I am 3.5 hours away from those who have bought the other 2 barrels in question. The only person I knew, was someone who knew those guys and passed the recommendation onto them. I don't have the kind of money to buy a bunch of barrels and test them out to figure out which one I wanted. I wish I did.

While the information is being compiled and sent to MBX. Here are a few pics from the results. This was shot with the provided MBX upper, mbx new barrel, mbx rail, using the 124g JHP MBX Loaded ammo This is using a different upper, mbx barrel, and midwest industries rail. and here is the results with the fiocchi ammo. same gun setup as the above. Only change was the ammo. The Black barrel, which was one of the ones that was sent back, and then return to the owner by MBX shot the following. Black Barrel, Milspec Upper, and midwest industries rail Black Barrel, milspec upper, midwest industries rail All of these test were done with 5 shot groups. 3 different shooters shot the builds with very similar results.

Test results are coming soon from independent test. As a quick rundown. When shot with 124g Precision Delta ammunition supplied by MBX, the new barrel that was sent from MBX shot like a champ. 0.60" groupings. The same gun, same shooter with Winchester White box, shot in the realm of 1.5" groupings. Fiocchi shot a 1.86" group at 25 yards. This was the most common theme across the board with all ammo types tested and barrels tested, regardless of the upper/rail/bolt combination. We found that no matter what shooter, or what setup. the 124 Precision Delta JHP, Hand loads, that mbx supplied, shot very tight groups. All other factory ammo shot 1.5" or greater groups.

my question to you is, why did you go from a JP barrel to the MBX?

I feel like it is something with our setup. But......our setups are drastically different IIRC.

I don't doubt their results. But that video sounded like a big F you to us having issues with our barrel. Saying our claims are false. Saying that you have to have someone behind the gun that can shoot. I'm going to be shooting my own video where I put my MBX barrel in. Shoot it. Then instal the JP barrel and shoot it. IF the MBX barrel still behaves in the manner that it did when I first had it installed. It will go back to MBX. I will say this. A lot of this could have been resolved a lot faster over the phone. Instead of forums and email.

I too shot multiple boxes of factory ammo. Same result. I was using a holosun 510c

That is the only thing I am thinking. I'm running the short stroke system from JP with their enhanced bolt. Perhaps its ringing the bell too hard and sending rounds flying. I am tempted to accept the invite and make a drive up there to see things hands on with them at their test range.

still makes me wonder how they got the same barrel to group better when they shot it. When it was shot by the owner, the grouping was 5" or greater. They shoot it, and magically they are 1" groupings.

I'd like to also mention on the 19th after i sent my reply email at 3:27 PM, 15 minutes after you guys emailed me. You posted a video on facebook at around 6pm.

You were closed on the 19th, 20th, and the 21st? You emailed me on the 19th and I replied almost immediately. I did not hear a single thing back until after I emailed you guys yesterday. I don't think anyone has questioned the validity of your results. We are all just at a loss as to what you guys do different with the barrel install that we have not done. It is not rocket science. You have not bent over backwards what so ever to help resolve these issues. All you have done for me is email me after almost a week delay the first time. Tell me that other barrels are shooting fine, then finally replying 6 days later to finally give me an address to send my barrel to. Where have you bent over backwards? You want us to ship you our guns so you can install the barrel and test yourself. Are you prepared to be responsible for our entire guns? If something happens during testing and a part breaks or our gun is damaged while in your care. Are you going to be responsible for that or just jerk us around as you have with the barrels. Please, explain how you have bent over backwards for us 3. All i can tell is that you have tried to save face and now are trying to make it out as WE are the bad guys. I can share the limited email conversations that we have had if you would like. Shitting on us as customers is not how business should be done. This matter is far from closed.

this made me chuckle!

You have made 2 post on this thread.... where does the notion of you being trolled? 300$ is not a “cheap” barrel. Not at all.

Yeah... They had the time to jump in here and try to save their reputation. Then vanish. I sent an email to them. Asking for a refund or an exchange. We will see how it goes.

Yeah. I replied to their email a week ago asking where I send my barrel to. But, does it even matter now? I feel that it is just going to go back to them and ill go through the same thing you are going through. What the heck do we do now?

They sent me an email with the pics from this thread on Wednesday. I replied that day and am still waiting on a reply. Their response times are less than stellar. Sitting here with a 300 dollar barrel and waiting days for emai replies. I went ahead and ordered a JP barrel and comp. I’ll probably have it before I get an email reply.

I really don't think the would have fudged them. I don't know them very well but many many have done a lot of business with them and they seems to be very reputable. I just would really like to know what they are doing different. It is not a difficult process. If it was some gun tuning issue, where there was a variable that we 3 are getting wrong then cool. But its 3 pieces. Barrel, Rail, and Upper.
