Has anyone come up with a way to trip the ejector door so that it opens when the bolt moves forward into battery? I would like to keep this feature if possible but didnt see it addressed in any builds so far.

Thanks!

I have been thinking the same thing. Might work on it this weekend.

I have not played with the door but was told the bottom of the bolt trips it? you definitly do not want to fire if it is closed

Well yes, ...the bottom of the bolt DOES trip it open. But with the SA mods you mill off the part of the original bolt that activates the door. I was wondering if anyone had come up wth work aound.

put a lump on the door so the bolt head will trip it

I think it would very diffcult to add material that large to the tiny spring loaded door trip that is all of 1/8" wide.

ARE YOU EVEN LOOKIN AT THIS STUFF TOM???

Vulcan, Look in the FAQ under the reciever heading, scenarioL113 posted some pictures of building up the material on the latch area so that the cocking handle would open the dust cover.

actualy no I am not lookin at it I am just throwin ideas out there the gun is at my house and I am only there 1 day a week but then guess not to many guys would know this since I never post here

...great. now I am being publically disparaged.

the shame.

You have build up the 'hump' on the cover that used to get hit by the bolt. Its tricky since youre dealing with pretty thin sheet metal that has a little spring under the hump. Take the spring and plunger out, build it up with weld and redrill as necessary. mine works as its supposed to but it took longer than the 15 minutes I had planned (like most things on the 42 build- lol)

Well I guess Tom was right. SORRY TOM!!!!

Im an ass.

Ok, I will have to look at it. My understanding is that the original bolt has two stubs that trigger the door. One for when the bolt is deading home and one for when you pull the charging handle back to eject a round.

just messin with you

Youre right about the original bolt/extension. Since you have to remove the part of it that hit the ramp/hump on the cover door, you have to increase the size- height- of the ramp/hump so its high enough to get hit by the extension as it moves fore/aft.

can someone please post some pics??? :-P

I have no clue what you guys are talking about.

i don't have any pics right now . sorry
mine isn't installed yet.
yes its for the 42, it is a small spring loaded trapdoor that covers the ejection port in front of the grip-stick.
i believe BRP just deleted this as it took too much effort to make this work and there wasn't enough profit on a 5K gun to be worth installing. <- sarcasm

This is what I did. I drilled a small hole and smacked a 5/32" rivet in there. Then put a small tack weld to keep it in. Works like a charm!

um stupid question but hows that big long a$$ rivet clear the fa bolt blocker in the reciever?

I offset the bolt block a little towards the right side of the receiver. I tried as best I could and could not get the F/A bolt in. Then I ground the rivet head on the right side so when looking from the top down onto the rivet it looks like a backwards D. The flat spot passes right on by the bolt block.
