View Full Version : Noveske does not make midlength gas 14.5 CHF uppers due to reliability

I just got of the phone with noveske in regards of a custom 14.5 midlength system upper like the afghan but without the stainless barrel. They tell me that they only use the 14.5 CFH barrels with the carbine gas system due to them not being reliable on the middie system but they magically work with the stainless. Just want to know your opinion on this? I already have a noveske lower and would like to complete it but I might have to get me another BCM upper since they make 14.5 middie

Get the BCM, it's better anyway...that would be my opinion, and that is what you were looking for.

the bcm would run much cheaper anyway. I like my noveske alot but i doubt i would ever buy one again...

Get the RifleGear mid-length 14.5 upper - same specs as the BCM at a better price!

Why midlength with a 14.5. Get the carbine, that's how it was designed.

Because carbines, especially the 16" ones, are overgassed. Mid-length will shoot a lot smoother.

Your right. Hence the midlength for the 16". But a 14.5 with CLGS isn't.

Wouldn't a 14.5" Carbine Length be as smooth as a 16" Middy? I would assume the 14.5" Middy beats them both.

the barrel length is not what determines the gas pressure.

Weeeeellllll......

It determines the length of time pressure exists within the system...but that all varies on gas system size too.

The carbine's gas system works most reliably with 10-12" barrels.

Even the 14.5's are over-gassed and benefit from a midlength tube.

its not just the length of the tube...there are a few other things that come into play...lol doesnt matter what length the tube is...you just gotta make sure it runs smooth.

what I dont understand is why would it be reliable in the stainless afghan upper and not on their CHF barrels???? Thanks guys for your input

So the distance from the end of the barrel on a 14.5 to the carbine port is 7.5". The distance on a 16" barrel to the midlength port is 7.5". The distance from the end of a 20" barrel to the rifle length port is.... Take a wild guess.....


7.5". Hmmmm.

That makes no sense.

A midlength tube is 2" longer than a carbine tube. How can you move the port two inches from a 14.5 to a 16 and still get the same measurement to the end of the barrel?

Same with a rifle length tube. It adds 3 inches to the tube, but 4 inches to the barrel.

Are measuring just the tube? Or are you measuring from the port to the end of barrel?

The gas ports on the tubes are the same lengths from the end. So if the tube is 2" longer, than the gas port needs to be drilled 2" further down the barrel.

but what Like I stated before how does the barrel being 14.5 " stainless in the afghan upper with midlength gas system very reliable but if they use CFH barrel it wouldnt. I feel they are try to blow some smoke up my WooHA. How does a stainless barrel of identical length make it reliable???

I think they fed you that BS because they just simply don't make 14.5 middys

Maybe because they don't make a CFH middy in 14.5? hahaha.

Disclaimer:I'm making a lightly humored wild accusation and my post should be regarded as such.

i think you have the option of coating your barrel in black or fde if you don't want it stainless

Faster velocity with a stainless barrel meaning less dwell time? Could be it. I'm not sure.

Randall would know for sure :)

looks great and i would buy it in a second, but i want it with a low-pro gas block and my extra dd omega rail, and the (future) battlecomp brake on it.

ok, that's my wife's requirement/wish-list, as it would go on her lower. :D

If your worried about a carbine length gas system being over gased or whatever get a heavier buffer like an H2 or H3 and a stronger spring and you'll be good to go.

Honestly, man.. I think 12-12.5in. is best for the carbine. 11.5in is acceptable. I'm not so sure on the 10.5..they're really iffy on the ammo varieties.

For a middy, sure a 14.5 on paper don't seem under gassed and could be picky about ammo types. However, with the BCMs (like the Pat Rogers middy), they've been tested extensively and there is absolutely NOTHING that supports any claim of them being unreliable.

But, again on paper, 15in. seems to be optimal for a middy!

That doesn't fix anything though. It just makes the negative effects a little less noticeable.
