Jeff: Are you using real-steel pivot/takedown pins and real-steel magazine catch? If so, What mods did you do to get them on or are they just a drop-in fit? As for fire-selector, how did you get the BAD-CASS on there in your older pictures... or is there any chance you will be selling the 45 degree selector centre? Thanks

I described the process required and the reason for the installation of the RS Pivot/Takedown pin on post #77 of this thread. The Pins I used, as Beach would have found through Google, is the Battle Arms Development ETP/EPP Set. They are absolutely superb by the way.

The Magazine catch was actually not Real-Steel. They are the Guarder steel Magazine catch and release button (the button is actually aluminium), and it required no mods to fit the MKM. In the photo I posted you could not actually see the allen screw on the button, as it was Photoshopped out to look more realistic.

The older pictures' B.A.D. Levers was attached to a modified Crusader Tech's B.A.D. Selector centre. It is completely incompatible with the PTS MKM, and one of my motivations to create the 45 degree ambi selector.

I do have plans to make some 45 degree selector centres to sell, but as they are quite tricky to mill, especially the 45 degree position divots, only a very limited run will be produced.

Hi Jeff, I need your help again.

I ordered the Guarded firing pin you recomended and am looking to install it.
Can you please confirm the correct lower body disassembly procedure?
I believe it would be as simple as removing the two pins that hold the tigger and hammer groups, but I applied some force and didn't accomplish much.
Do they have a particular side to push towards or some kind of safety block?

Thanks!

No need to remove the trigger group to get to the firing pin.

Boobie, I'd be much obliged if you could tell me how it's supposed to be done, I'm no expert. Thanks!

So I have installed the ra tech 6.01 and maple leaf bucking and tension arm into my mega arms. I've read through the other post specifically for this setup and have made minor bends in the arm to add more tension. I'm running with ksc .30 bbs and it seems I'm not getting the range I want it to yet. It seems the bbs curve down still.  I've seen through thr other thread that I need to bend the arm to add more tension which I have done and still need to fine tune, but as another poster said, it seems like there is little to visual signs if the hop adjustment when the set up is put together before throwing it back into the gun. Has anyone else experienced this and\or have any thoughts and suggestions?

Just keep putting a little more bend in the arm and testing. Try not to bend it back and forth too much because it will break.

To any of you fine people that have been able to get the barrel nut off, how did you do it? I was able to buy the proprietary wrench straight from Mega Arms. It fits perfectly, but the nut just will not budge. I've tried heating up with a hair dryer for 10 mins, using a mallet on it, but it's still super stubborn. Only thing to add is that the gas block is still attached, but I'm not sure that makes a difference. Any ideas?

The Selector is coming along... just waiting for some stock parts from Yih kai to arrive to complete the kit. In the mean time I have sent out a sample for T&E, which you should hear about soon...!

@ZeroPoint, Is the GasTube still installed ?
Ofcourse you have to remove the Gastube before youre able to unscrew the Barrelnut :)

I get my Mega Arms next Days:) Few Questions:

1. About LM4 PMAGS, is here a better Workaround to make them work with the MKM ?

2. LM4 Parts Compatibility in MKM ?
- Fire Selelector like PTS Ambi or Cusader will both not fit?
- Guarder Steel Mag Release ?  (Solved, will fit!)
- bba Steel Buffer Stop
- Guarder KSC LM4 Steel Outer Barrel ?

3. Anybody use the TeamGBB Metal Speed Buffer ? The Plastic Recoilbuffer is a no go ;)
RealSteel Buffer?

Thanks

I don't know if it really fits but as it looks like Angry gun super recoil buffer or the Hammerson combat; maybe you will have some problems as bobbie told in one of his videos. As the bolt returns faster it kis harder forward and could brake something; if i'm not wrong he broke the bolt catch. I'm planning to order the crusader BadAss selector and RaTech barrel, i was thinking also buying the TeamGBB buffer but i'm not sure how it work. If someone has had experience with it please tell us :)

So far i know Crusader Selector and others for LM4 will not fit into the MKM !
The Receiver Dimensions and Detent Pin Location is different!

I really hope PTS will bring the announced BAD a** or their SSG Selector for the MKM!
The standard selector is really bad imho, no positive Click, feels not secured at all

I took a closer look o the TeamGBB Buffer, Would not buy it anymore!
Speed Up the Bolt Travel is no Option
A simple A15 Buffer is what i want as replacement, i will see if a RS buffer or the one from my Inokatsu will fit:;

I have a few Queestions to PTS, they told me we have to post it on Facebook;)
I dont use Facebook and i know from a Fried that they rarely answer to Comments.
So no Support for a 480$ ( 540 in EU)  Gun from PTS ? Ofcourse KWA doesnt give Support here
A bit sad when you ask me;)
