M76 - To Fire or Not?

Post by Phil_D

Dilemma,

I picked up a unfired M76 recently without rounds.
Due to the kindness of Shazhib, he sent me 5 old ones for free which I used as a guide to start making some new open ended rounds….

Not quite finished here...


Now the bolt on this model has no marks on the face...



and even has the molding flashing still attached !!

Well I have a few models I keep in like new, unfired condition, they are so nice and new despite their age so I ain´t got the heart to fire them.

I think that you should shoot it! Especially if you are going to manufacture new cartridges for it! The bolts are very brittle some last for hundreds of rounds and others last for a few rounds. I think that the best idea is to make a new bolt out of aluminum to keep the bolt lite enough to not break the front of the receiver off..

if its with box ...dont fire it.

if its loose .....let rip

it will have higher value if all minty boxed , if loose then the condition does not add to much to it IMO

Definitely fire it

PFC Modelgun = replicate firing

Deactivated gun = Wall hanger/display

fire it after oct you cant sell it anyway so value means nothing, by the way if you are making the rounds any chance of making a few more as i could do with more rounds for mine and another det pin as mine is not in good nick.

You have the equipment to make your own rounds?

I've got a shell ejecting gas airsoft uzi that uses the dinky plastic shells that keep breaking at the rim... been wondering about trying to get some rounds made out of aluminum or brass barstock, but wasn't sure how I'd go about doing that. Suggestions? Where would I go to find someone with a lathe?

Phil_D,

I totally understand your feeling.
I have easier accesss to old/new modelgun here, but still sometime wonder whether or not I want to shoot. In a past, I did re-sell many models I get with intention of firing, but end up not firing and re-sell it.

Here is one point.
Remember a mening or presence of modelgun, especially, one from MGC. It is meant to fire and enjoy it. If this is were Sterling or 68 metal MP40 in superb condition, then, might be a different story, but M76 is not easy, but not difficult model to get from an auction. I can help you out on that.

"Go ahead, make your day!!"

So what was the outcome? Are you planning to shoot it or?

BTW Tip :
I use a modded Det pin and old type Marushin M84 rounds in mine I and they work perfect.
I`ve not tried new type M84 rounds but presume they would work fine too

Mark,
Yes i will be firing it

fightdesigner,
The open ended ones are easy enough to make on a lathe and some of the mini lathes in the US are really cheap - go on, have a go

Doc,
Thanks for tip, worth knowing if my home made ones dont work out.

Claymore,
Let me see how they go first and if ok, i can make a few for you.


Cheers

ok it has been fired, well it went pfffff with smoke...

I need to make some adjustments to the det pin to get it to blow back smoothly, but atleast the end never flew off !

Phil_D,

Are you using your original Det pin?
Remember, a clearance between Det pin and a round is very sensitive. Other suggestion is to apply grease (not hard & thick one) to an inner wall of the round using ear cottons. This may helps after you did a right adjustment of the Det pin. If you happen to get original Det-pin, do not think to touch that, from the clearance point of view.

Regards,

P.S.
If you changed your mind and get whole gun, let me know.

Post by Phil_D

I never had the proper det pin, so i quickly made one last night based on the picture you sent me but i made it with a longer sealing section, obviously it too long so tonight i will reduce it so it looks the same as yours.

Cheers

Phil_D,

Yes, try to replica the shape as much as you can.
MGC had a patent on this detonator system, no other makers were allow to copy the shape. The reason for most of MGC's open rounds detonator has a mushroom head is, if you have wider are where having contact with an inner wall of the rounds, it allows easily to build up firing residuals around the detonator head which end up miss firing or stucking rounds in a chamber.

Good luck!

Which is exactly what i found Thanks mate, will let know how it goes.
