tm tAc master problem
 

i tried the search function but couldnt find anything. i got a used tm m9 with a bent valve fill. It somewhat fills. My problem is it doesnt always shoot a bb unless i rack the slide which manually loads a bb then it shoots once. Then dry fires unless i rack the slide again. It shoots nice n hard. Ive cleaned and superlubed the slide and mag. Thanks for the help in advance. Since it is a used gun i wanna try and fix it myself.

Sounds like a problem with the gas hammer or gas hammer spring. It may be damaged/broken.

I just found a full lower frame brake down. Wow looks like fun.

Well it would help if I had the diagram as well. Fortunately I know where to find one:

It would be part 92B-41 or 92B-42, or both.

Thank u very much. Is there any way short of taking the whole lower frame apart of knowing it is those two parts.

No.

Well....you might be able to but you have to know what to look for. It sounds like you don't. If that's the case you should get someone experienced to work on it. If you can't find someone local (you don't list where you are in your profile) I can fix it.

Im in toronto. One of the reasons i bought it used was if there was something wrong i wouldnt feel as bad taking it apart. Im new to airsoft but with anything i do i am obsessive about and like to tinker with.i take my time with and have all angles checked. i wont just dive right in and break stuff. Anyways thanks for the advice. You have been a great help. the tm is my project i guess.lol
Off topic i bought a brand new we baby hi capa and wondering if you or anyone knows where i can get a full metal lower frame since this tinted plastic will crack soon. thanks again

Without being age verified, no we can't tell you.
