That's my guess, too. Fairly consistent double-feeds/FTE.

The unfortunate part is the tolerances on the extractor or spring aren't available, nor the ability to throw spare parts at it. This gun lives and dies by Tom Bostic's customer service.

As far as the shenanigans on the first drop, I agree. There was a frenzy when it went live. Then everything crashed and people thought the drop would be canceled. A few minutes later I got as far as the payment page before the out of stock error.

I don’t think there was any issue with the MGW drop. I got the email clicked the link logged in and purchased. Maybe some people don’t have their login info saved in the browser.

As for the T7 drop, it was a DDOS detector that shut down the server for 20 minutes and then came back up.

Is the top pic rail out of spec?

I mean technically it would work - the base stock Holosun mounts mount solidly.

I know, but the DDOS detection was a false positive based in part on the pings from the site change detectors.

Apparently this was an issue on the actual MP7s based on what I’ve read. The strike industries rail fixes this problem. As much as it pains me to buy anything SI, I ordered one just now to alleviate any optic mounting issues. T7 is finally at my FFL today.

I'll try out some of our Aimpoint micro mounts next week (if mine ever gets delivered) and report back.

Saw that same attitude on a groups post too as well as HKP. It's like the fact that these things are having major issues needs to be kept a secret or some shit by some select key guys. Kinda BS. It's getting to the point where no new buyers are going to feel comfortable discussing legit issues or constructive criticism of the gun.

They want no personal attacks on TB. Discussion of problems or technical issues is welcome, but some people, most of whom do not have one of the guns, are going after him personally. That’s not cool, because TB has always stood by his product even if he can’t fix the issues.

How reloadable is 4.6mm? Does it have the same issues that 5.7 has with weird lubricating coating?

I would really really like to buy a single empty casing for my cartridge collection if anyone would be willing to send me one please PM me.

Their is no case coating like 5.7 so it is simpler. dies are available but sourcing the bullets is difficult however.

Tom is a great guy, quick to answer, always willing to fix any problems you have with your purchases. I have gotten both a UMP45 and G36K conversions done through him and they have worked flawlessly over the last 4 years and I couldn't be happier checking those off my bucket list.

But MAN am I glad I was not an early adopter of the T7...
I have no doubts Tom will sort this out in the long run, but the PR from this is quite damaging.

My selfish issue with all of this is that all the T7 issues will likely drag out how long he has to devote 110% of his time to it, delaying when he will do conversions again.  Sitting on a usc and ump parts kit wasting away.

Picked up my black T7 today. My B&T suppressor spins on it unfortunately so I’ll be sending it back to B&T. The gun itself looks great, no cosmetic issues. Can’t wait to shoot it.

Not canted. I did order the strike industries rail which will be here Monday though just in case but it isn’t an issue.

Range report: black T7, serial number in high 200s. I fired about 75 rounds of Fiocchi range dynamics ammo before giving up.

LOTS of FTEs. Including when I would only load one round in a mag…A couple times the gun wouldn’t even lock back on the empty mag.

The gun was lubed and I wasn’t limpwristing it.

I wasn’t using my suppressor and was shooting what is supposedly under powered ammo. I have some Hornady Black arriving tomorrow. I’m going to try one more time with a suppressor (when I get it back from warranty work at B&T) and with Hornady Black before contacting Tommy. Hopefully the gun is just really tight and some good back pressure and hot ammo will help.

My gun was barely cycling with Fiocchi and when fired cases did eject they piled up in a nice group just a couple feet away from me. That makes me think the Fiocchi is a bit underpowered for the type of gun it would be used in, or the gun just needs a suppressor and hotter ammo. Or break-in isn't complete. Too soon to tell frankly with only about 75 rounds through it.

Being fairly ignorant on the platform, is there no adjustability in the gas system?
If all it needs is more gas with commercial ammo vs the hottest AP mil ammo it like like a commercial adaptation should include adjustable gas.

Considering the guns' reliability is still hit or miss with the current 4.6 selection on the market, a conversion kit is WAY down the road.

I get that and that isn't a concern, but curious as to if there are plans for a conversion. If no conversion, I will likely wait for the 5.7 option to be released.

I'd look at the MP7 you have at home (PSA X57).
There are currently no 5.7 mags in the MP7 pattern and Tom has said that they would have to develop one.

I don't think it's a gas problem. The early guns had loose pinholes in the backplates which allowed the trigger assembly to move a bit. Maybe tight ejector springs too. I picked up mine on Friday from the end of the first batch and took it to the range yesterday. It ran absolutely Flawless with Fiocchi blue box in 30 and 40 rnd magazines.  The bolt locked back on every empty mag and nothing is loose anywhere. In fact, the pins are extremely tight in the backplate and came with silver anti-seize on them. I had to use a urethane mallet and punches to get them out. Not a big deal considering how well it worked. Round count was 150 in pistol configuration with an HK bungee sling. Form1 is filed.

Got 480 rounds in today. Started off finicky with a couple hiccups but nothing crazy. Then started to shoot super smooth for about 200 rounds before having issues again. Left the range a little disappointed but was a little relieved after getting home and cleaning the T7 where I found a primer in the trigger group. Shot suppressed and unsuppressed fiocchi FSP and ball. My presumption is that ended up causing the later issues so plan to go back out this weekend and try again and see what happens. Got a couple videos that I will try to add later.

Waited until I got the Form 1 approved to post pics cause the pistol mode is gross.

I’m in love with this thing….mid 200s SN, build quality is better than expected with not much flashing, pins are tight, gas block centered. Everything seems tight and I see very minimal machining marks on the trigger and safety.

Decided to go the EXPS 3-0 route, and put my LA5B PEQ15 on it. Ergos are great.
