I just installed an MBT in my Aero M5 lower. The trigger itself moves freely. The hammer disengages like normal, but it doesnt "spring" forward. It gets stuck halfway up the stroke. It is difficult to cock the hammer back.

I attempted to disassemble and reassemble with lots of lube, same result. The movement of the hammer feels very gritty. I checked the walls of the pocket, and there are no binding marks. I switched hammer pins, same result. I had a Geissele SSA-E in it previously and it worked fine.

If you could post a picture from the top looking down into the trigger group it would really help in diagnosing the problem. I am guessing the hammer spring is backwards.

Are you using a Battle Arms selector? Yes. Ding ding ding! That would be news to me since I have three of each playing nicely together. |

Quoted: I am guessing the hammer spring is backwards. View Quote I installed the hammer exactly from the package/factory. The hammer follows through normally if the hammer pin isn't through the other side of the receiver; such as being slightly crooked in the pocket. I checked the spring and it isn't "squished" or binding to the sides. |

Have you tired installing with the supplied hammer and trigger pins instead of the anti rotational pins?

I have noticed that the pins will rotate when the hammer reciprocates. Could it be the j-spring causing the binding? I will try the MBT into another receiver in 9 days. Sucks to have this problem the night before my flight. |

I put one in my M5 and it worked well. I put one in an 80% lower and it acted just as you described in reference to the reset. After the trigger broke there was zero additional movement rearward. Extremely tight.
Are those anti walk screws on the outside of the lower? If so, any chance they are causing the pin to bind by not allowing the hammer pin to rotate if it's tight? |

BAD short-throw selectors with the titanium nitride coating have been failing to work with both Geissele and LaRue triggers. The old phosphated ones don't have this problem. BAD says it's the users fault for using a non-milspec trigger, but they haven't addressed whatever changes they made in this last generation that cause the problem. If you call BAD they'll apparently walk you through filing off enough material to make it work, but it's shitty customer service to blame the customer when you produce a faulty product and you know that your selectors are predominantly used with aftermarker triggers, especially when they charge what they do. There was a thread on one of TOS about this a while back.

I tried to go over this with George near six months ago, I even made him a diorama to depict the issue with the selector barrels. |

The problem was due to the BAD-ASS-ST selector. I used V7 selector and it works beautifully.

I have no idea what they changed on the new generation of selectors, but they cocked it right in the ear. I just took an older, non-reversible, non Ti-Ni coated selector out of my 14.5" Stealth build and moved it into a new build that was utilizing an MBT and one of the new coated cores, and it works fine. Moved the new selector into the Stealth build that has a Geissele, same problem. It's a damn AR, not a 1911, nobody should have to remove material from their trigger because Battle Arms decided to "fix" something. |

looks like i will be giving the seekins or AXTS a try on my 2.0 build
|

AXTS and Seekins both make good stuff. The AXTS charging handle is absolutely my new favorite. It just works awesomely!!! I have only used a couple of Seekins parts but they are machined nicely and look and work well.

If you take the same selector and you change it to the 90 config it works....there is your sign |

So... I posted in the Battle Arms subforum with the description of my problem. George told me to email [email protected], and so I did. This was the reply.
"We don't make a Ti center safety selector, we used to make one that was Ti Nit coated and had a gold color to it. Some trigger groups will require fitting in order to use our safeties. Kind Regards, Sales Team - Retail Department Battle Arms Development Inc." Hmm, no way I will take a file to the MBT. |

George got someone to contact me again and they gave me a RMA for an exchange of the center. BAD stopped producing the centers with the TiN coating because of issues with LaRue and Geissele triggers. They are now back to the phosphate coated centers.

I have one of these i was gonna drop into my larue build. Now i guess its gonna be an issue. Any way to tell if you have one that is ok or one that is fooked without building it yet? I dont have a chance to assemble it anytime soon.

I received a replacement phosphated 90/50 degree core from BAD and it works without issue.
