MSBS 5,56 - new Polish assault rifle prototype

[REMOV]

The preprototype of the MSBS-5,56 bullpup design standard assault rifle in action

[REMOV]

Good progress I say , a couple of questions come to mind :
1. Do both versions have ambi ejection ports ?

Yes.

2. On the bullpup the selection level looks like its on the rear of the reciever - will it get moved to a 'better' postion.

Sure. Now the preprototypes (demonstrators) are just testbed for the action of the rifles, the target weapon will be far different than those two rough models. And it looks, well... very advanced in the first sketches.

3. Whats the optic sight fitted to the bullpup in Remov's pics

There were commercial sights, not Polish one. Just for test purposes, like Magpul magazines.

Remov,

Thanks , hopefully we will see these designs at MSPO in September or maybe before. If Radom pull off a credible bullpup featuring ambi ejection options , barrel length and ergonomic controls this could do well .

Remov , thank you for posting - excelent - the Bullpup version is looking very promising - what will the barrel length options be ?

[YevgenyP]

looks good

Both bullpup and classic standard assault rifle barrel length will be 406 mm (16 in.), the carbine version will be about 256 mm (10 in.), maybe a bit longer. The precision rifle and machine rifle version barrel length is unknown yet, but I think the longest will be 508 mm (20 in.).

As for the ergonomy - looks suprisingly good (although definitely based on ACR, which is actually a good thing).
I'm curious about manufacturing technology. I quess the body (upper & lower receiver) will be alluminium alloy.
The question is: will it be a casting or a hog out?

[Bro Jangles]

the angle of the pistol grip on the bullpup looks a bit iffy, but with out holding it im only guessing.

I actually like that 2nd gen bullpup! That looks promising!

[Arnie100]

I dont know probably because its polish as they haven't really made any decent guns yet.

AFAIK the upper receiver will be made from grinded aluminium. just like the new monocoque macbook pro series

it's more or less the same angle that is featured in the X-95 Micro Tavor.
take note it has been changed when compared to the "adult" TAR-21
and the MSBS bull-pup is very compact also...

Are Magpul\Bushmaster\Remington going to sue Poland?
