For CQB is a high rpm really needed (1000 to 1150 like UZI PRO SMG) or 700 rpm is enough that you can find for the Saab Bofors Dynamics CBJ-MS (see below) it's chambered for both 6.5×25mm CBJ and 9×19mm DISASSEMBLY pictures

I’d go 40-10 on BF4 with this thing.

The smaller variants of the Uzi fire so fast because of the reduced bolt weight compared to the full-size Uzi, not because that's somehow more optimal for CQB.
I could be wrong I think opr8trz typically prefer 700-800RPM because of the controllability. Really fast cyclic rates are only preferable in certain belt-fed and vehicle-mounted/aircraft applications.

It's moreso the shortened reciever. Theres less dwell time between firing and hitting the rear of the reciever and bouncing back. Theres no delay in the action so mechanically speaking she's bookin.

It’s a combination of less bolt mass as you stated, along with a shorter receiver limiting the distance the bolt travels that drives the higher cyclic rate of the Mini and Micro Uzi’s.

exactely the answer i research thanks =)

The cyclic rate only really becomes relevant when you’re firing the weapon in full auto. However, submachine guns have largely fallen out of favor with many police and military units in the US, and even when issued, they are not used in full auto during any duty situation or a military operation. Semi-automatic fire is preferred for accuracy and control, with modern weapon choices leaning toward short-barreled rifles in 5.56, closed-bolt 9mm submachine guns (still widely used in Europe), or PDW-style platforms chambered in 9mm, 5.7, or 4.6.

Isnt an Acog and bipod on that sucker a little optimistic?

Target discrimination and identification. Easier to see the head poking around a corner.
Stability is always nice. And it makes it easier if you're focusing on a specific area and prone or using a table or counter.

You don't need to be a mile away from your target to appreciate magnification and steady aim

Are you gonna be able to tell the difference between getting shot 8 times in the chest and 10 times in the chest? Controllability is important to ensure that those shots land where they need to.
Also, CQB is a relatively rare use-case for a firearm. Most people doing frequent CQB are using M4s because the M4 is pretty decent at most things. The main advantage to a gun like this would be concealability and ease of carry, but the trade off is lack of armor penetration and less catastrophic terminal ballistics.

Yep i agree with all that

Cool caliber. I would love some .300 CBJ for my FA lower. Is it similar? A plastic sabot?
