Hi-Point 40 to 10mm carbine

[General Tso]

Is it possible/safe to convert a hi-point 4095 to fire 10mm? I ask this because I know of no other 10mm carbines, which seems odd. I would think the 10mm would be a great carbine round.

Mech Tech makes a 1911 carbine upper in 10mm, and I think there are a couple of other outfits that may do AR15 uppers as well.

10mm is rumored (confirmed?) to be one of the cartridges that MSAR's upcoming AUG-style carbine will be chambered in. It'll use Glock mags.

COOL!

Hi Point is a big negative. It's too small of an ejection port and mag well. You'd need longer mags.

Additionally, consider that the Hi-Points are made of zinc alloy and work via blowback. I believe the cartridges only have a difference in SAAMI specs of 2500 PSI, but any conversion would have to consider receiver strength and bolt mass as well.

Given the safety margin used in firearm engineering, the gun theoretically could "take" the slight increase in pressure, but the additional slide velocity would wear the moving components faster.

Oly makes a 10mm AR. Vector used to make a 10mm HK-94/MP-5 clone.

I think 10mm might be a bit "intense" for a straight blowback action made of non-ferrous metal.

BTW, I've been impressed with new ones with the restyled stock (handled only). They are almost - dare I say it - not bad looking.

Here's a couple 10mm carbines. Feather USA (http://www.guns-rifles-firearms.com/) also makes a 10mm carbine that uses Glock mags.

Thanks Nordic.

Olympic Arms has been making a 10mm AR-15 carbine for more than a decade?

Here's mine and they have new polymer magazines in all pistol caliber now:
