Q about BullPup Design gun ejection port

[Wiriyapol]

Hi, I have some quick question.

Can LeftHand Soldier use BullPup Design Gun like Austrian AUG or French FA-MAS ?

From the ejection port position, Seem like the bullet jacket will hit their face while firing

Or can they swap the ejection port side for LeftHand soldier ?


And I wonder FN P-90 & F2000 have some problem about their ejection port??

I'm just an Industrial Designer but curious to know, Thank you.

Well, I'm not left handed, and I've no experience with bullpups but . . .

The P90 ejects downward. So no problem for lefties. You can see the ejection port behind the rear grip.

The Steyr Aug can switch ejection sides by replacing some parts.

The FAMAS can change ejection side by shifting parts on the rifle.

The FN 2000 has foward ejection. Don't ask me. You'll have to read the description.

There are a number of people on this board that have used bullpup designs in service. They may be able to give better answers.

But you must have a special stock!the military issued don´t have it.For example in Austria, "left hander" must shoot like a "right hander"!

The SA80 can only be fired right-handed.

With the Steyr Aug you put in a left hand firers bolt and then change the port ejection cover to the other side. It's still a drama doing drills because the cocking handle is on the left hand side.

If I remember correctly, with FAMAS you only needed to switch large ejection port cover from side to side. Maybe some Frenchmen can comment.

I have to say that I am surprised that so few bullpup designers have tried to produce truly ambidextrous rifles; the FN F2000 is the only one I know (although some of the Russian designs have also featured forward eject). Possibly their military customers didn't ask for it?

I can think of two other ways of achieving this without needing to fiddle about changing parts on the gun:

1. Have an upward eject, arranged so that the cases are deflected off the underside of the cheekpiece. Design it so that the cheekpiece can be flipped over for right or left hand use, automatically switching the ejection away from the shooter.

2. Have a top-mounted drum magazine (which can do double-duty as a cheekpiece) combined with downward eject.

In fact you have to field strip it, remove the extractor, firing pin and counterwieght from the bolt assembly, switch ther side, replace, and then swith the side of the plastic cover (that is also your jaw piece).

Definitely not a thirty second stress situation operation, but feasible quickly.

Heheh so it's not all that easy, hope I'll have a chance to play with FAMAS later this year, then I'll see to it. ;)

Yeah! Thank you

Apparently they dont do many left hand steyrs in the aus army, we went for a shoot and they had a couple but they said they were bloody hard to find.

Im a lefty, but i prefer to shoot with the right, plus the rifle feels better on the right.

Can't they put them on the right as well?

[Cardinal]

The AUG's in our service have a sort of deflector cap over the ejection port, so that left-handed shooters can also fire them without any problems.

99% would be on the right mate, that's how they come out of the box.
I never saw a lefty forced into using a right hand weapon, the Q ies were made aware of left hand firers and the weapons were made available. I did see a bloke (a lefty) who couldn't get his normal weapon out, for what ever reason and just took another one with out thinking. He fired it like he normally would and got a heap of burn marks on his face, which amused us for quite some time. :P

Woo!u guys are bad. ;)

It's not so simple unfortunately, if you only switch the side of the check-rest/dust cover, you risk to get hurt, coz the ejection side stay the same. So, if you you're lefty as me, you must dismount all the breechblock assy/bolt and switch the side of the extractor (17) and obturator (16) : http://www.sturmgewehr.com/bhinton/FAMAS/FAMAS_DiagramBoltGroup.jpg

Thanks a lot Decide! That diagram gives me a far better idea what to do.
Not to mention I owe you at least a beer for finding Buddy Hinton's excessive archive of materials on FAMAS which I've lost track of a good while ago. :hug:
