Unusual RT Pro Issue. . .Now confirmed as micromag 2k9 problem!

[Coralis]

wouldn't making a longer power tube tip be easier to make and less likely to fail than modifying or making a new bolt?

[Dukie]

mainly you, sniper, dukie, and athomas....yall are sum BAD MoFoS!!!!

Thats why they pay me the big bucks lol.

I wouldnt recomend sleeving a level 10 bolt. it you weaken the shrink fit of the power tube pin it will come out of there like a tiny steel dart.

Instead of messing with the bolt at all i would just borrow a breech from someone with a working one to confirm the issue, then just buy a new breech. or beg for a warranty replacement. they *should* be interchangeable barring the deed port location issue.

To my knowledge, this is the first MM2K9 body with this issue to be remedied, so nice job AO!

All of the holes on the bottom would be machined in one operation. That means that everything would still mount up correctly but if the zero point for the program was off by .150" it would move all of those holes by .150".

it sounds like only the breech measurements are off and since the feed hole wasnt directly centered it sure does sound like if it was accidentally machined backwards all tha problems your having would be happening? tha main body was prolly machined with tha frame screw holes, sear slot, and the breach screw holes...but when tha breach was machined a possible mistake was made and it was machined backwards. tha breach will still line up with tha screw holes to hold the breach in place but tha feed hole wont be in tha proper place? after reading all this that seems to be the most logical explanation for something like that to have POSSIBLY happened.

Not necessarily. We've determined that the length from the rear screw to the bolt spring seat can vary greatly and still work.

It really all depends on their processing. I'd have to see what they used for datums in each of their unknown number of setups.

Ah yeah.. was actually thrown off by those stoopid imperial units. Mentally converted that to much larger offset. But if the change was more like 5 mm or more it would likely miss align the on/off hole.

[nak81783]

Yeah but then they wouldn't match with the valve. The body would also need to gain or loose that much more length on the back and move the frame mounting screw hole as well.

its pretty safe to say that some of tha bodies...tha ones with tha velocity issues....might have had the breach machined backwards, which would have moved the feed hole just a lil further than it should have been. nobody ever complained about having any issues with mounting tha frames or any sear issues did they?

have you guys asked Luke to take proper measurements of tha MM2K9 that he is selling to see what measurements he comes up with? maybe ask if he will test tha velocity on his MM2K9 as well...see if he will help yall out?

yeah that makes more sense. because my dust black one is great and works proper. it sucks that people have these issues.

is there a way to get a total tally of people who have these issues and present them to PTP?
if you went to them with a full number of how many new breeches need to be made, maybe they will make some replacements?

I'm guessing that either the breach operation or the entire bottom operation with the grip frame holes, sear hole etc was offset by .150 and an entire batch got machined that way. Hence why there are a few markers out there that have the same issue.

[OPBN]

I still don't get why some work and some don't. I would really like you and I to send our bodies to someone to compare to see what the difference is.

[sniper42]

I had that thought. This one will be more of a proof of concept until I can come up with a more permanent one. The last thing I want is to shoot part of my bolt at someone.

[need4reebs]

can you make a sleeve for tha bolt you made to replace a lvl 10 bolt? have you figured out wat dimension/dimensions were off on that bolt?
