    Default MP5 10mm Trunnion question

    Quick MP5 10mm trunnion / build question, please:

    MP5 10mm build - all parts from HKparts.net.


    Trunnion question - the MP5 10mm trunnion includes the bullet guides already installed. Do I have to add any weld to these or being factory installed, are they good to go? No call back from HK parts so I'm turning to the professionals here.

    I just didn't want to complete the build and find out I should have welded them in place.

    Thanks for any help you all can offer.

    If its rcm or German hk. No need to weld. If its neither I can't comment. I'd personally go rcm or hk.
    Spent most of my tax return on Hk parts, booze and ammo....the rest I just wasted

    Thank you. HKparts.net is selling the USA built trunion that is built to HK factory specs. I'm sure this will work well.

    I’d be weary about that trunion, as I have heard many issues with 40/10 trunions that aren’t German or RCM.

    EVERY other part in the HKparts catalog that is RCM is labeled as RCM. This one is just labeled as USA.

    Yea the USA marked parts without a vendor listed are usually Todd Bailey parts(we found this out from Adam's trial). I'd personally avoid it.

    This would be my recommendation. The above guy will be the one to answer this but they are coming out with 10mm barrels as well. I'd go with one of them over the usa marked one from hk parts. That is unless you managed to source a german barrel.
