Dang it no one ever shows how to remove the feed cover. I can't get the pin to slide out.

[BongoOldChap]

@smokytyrz are you talking about the hinge pin? youre trying to take the entire feed cover off?

[Gumpa2]

@BongoOldChap yea mabe he has the mark 2 versionl, and wants to place one with rails

[BongoOldChap]

@Gumpa2 probably, the para version has a long 20mm RIS, Ive got a ELCAN mounted on mine, looks the shiz, its easier to mod the mk1 and 2 covers by removing the rear sight and mounting a g36c front rail instead using 2 bolts

Oh sheesh... You sure werent kidding about the standard motor heating up... I actually saw smoke coming out of the cylinder once! Thats definetly why the gun jams... Theres sometimes the nasty smell of an electric burn... All I have is one simple question: Did you have to do anything to your gearbox to get that new marui motor to fit? I'm asking coz I remember reading from somewhere that the gearbox's engine space would be smaller than usual... Is that true?

[BongoOldChap]

@Maksymaxi sometimes you may have to shave some of the metal from the gearbox motor adjustment screw area so that there is some room, ive marked a annotation on the video at 6.08 to show where, this is not true of all gearboxes though, out of two m249 ive only done it to one

That gun is beautiful and the us army crate is sick man if you ever sell it I may buy mines a TOP and parts are hella hard to find but again admiring your LMG

Hi, I own a CA Saw para and where the barrel unhooks (the metal slide it comes off) is bent and i have to force it on and off when i take it off. One of my friends put all his weight on it when it wasn't on all the way and bent it. How would I repair this or am I F'ed?

[skillcape14]

what type of piston is that my front tooth broke

[skydude38]

With the bbs in it, does it have like a shotgun affect? How heavy was the dumby?

[smokytyrz]

@BongoOldChap Yes. And I have now got it done. Needed a hammer instead of a mallet. Was being too gentle. Pin came right out. But now I can't get the new feed cover to shut. It seems like the only difference between my stock feed cover and the new one (G&P I think) is the shut latch on the cover is further to the rear, making it fall behind the "tooth" on the mechbox. Do I need to reverse this tooth so the feed cover will latch? Thx

[smokytyrz]

@BongoOldChap Yup! I've tried rotating the cover to the sweet spot and hammering that pin out but it won't budge. Is there a set screw somewhere? Thx!
