I have a 14.5, It shoots, cycles everything I put in it, both suppressed, and un suppressed, super and subsonics.

Yes, I am a Baptist, and yes I carry a gun. You might think I carry a gun because I don't trust God. Well you would be wrong. I have complete faith in my Lord. It is mankind I have no trust in

Rainier arms 14.5" barrels for the 300 blk are all carbine gas systems.
Re: 300 14.5 with a carbine gas system
I recently cut down a Noveske 16" carbine gas to 14.5". Subs without a can wouldn't run. I didn't up the gas port, it was less than .125", as the owner didn't care about subs w/o a can and didn't want harder cycling with supers.

Holy thread revival! Any updates on these builds for reliability?
I have a KAC MRE that I was planning on doing a 5.56 build but I've got 5 of them and would like an iron sighted 300 BLK rifle.
I like the look of the 14.5 pinned instead of 16 if I can get one.
Who makes a 14.5" carbine gas 300 BLK. I don't need subs to cycle without a can and will probably be a super sonic shooting rifle 99% of the time.

Re: 300 14.5 with a carbine gas system
On a side note, I have a 16" with carbine length gas and it doesn't cycle heavy unsuppressed subsonics. Regular gas block. I don't care that much as I plan to just shoot supers but it would have been nice to run anything. It'll cycle some 200gr but not 220gr.
Re: 300 14.5 with a carbine gas system
That sounds like a load issue more than a rifle issue, in theory the 220 should be easier to cycle. This is why carbine gas systems got a bad reputation. When often it was the ammo.Austin26 wrote: ↑Sun May 31, 2020 9:09 am On a side note, I have a 16" with carbine length gas and it doesn't cycle heavy unsuppressed subsonics. Regular gas block.

300 Blackout, not just for sub-sonics.
Re: 300 14.5 with a carbine gas system
Hmm, I'll keep an open mind then and try some other sub ammo. I've been trying quite a few brands of ammo though mostly supers. I don't understand how that's possible though being that supers travel much faster, meaning that it's a more powerful explosion with more power to cycle. What am I missing?dellet wrote: ↑Sun May 31, 2020 12:47 pmThat sounds like a load issue more than a rifle issue, in theory the 220 should be easier to cycle.

A couple things, attention to detail being one.Austin26 wrote: ↑Thu Jun 11, 2020 8:25 pmHmm, I'll keep an open mind then and try some other sub ammo.

Supers are generally never a problem with factory ammo. Subs often can be. Without the details of how the rifle is assembled, nothing is for certain. But........
With subs, the heavier the bullet, the more likely it is to cycle unsuppressed. You said your rifle will cycle 200 grain, but not 220, my reply of there is a good chance it’s more likely the ammo than the rifle, reflects that.
It would also be helpful to know what they ammo is the does/does not work. There is plenty of crap ammo out there, that people blame the rifle or operating system for.
300 Blackout, not just for sub-sonics.
