Can a Rifle length work w/ .223?

[sewvacman]

I'm not using special springs, standard carbine or rifle. Guess I need to take'em down and do some inspecting. Thanks to all who responded.

What ammo are you running?... Like I said... some ammo, Like PMC bronze has the wrong propellant in it.

Stuff like that has choked my 20 inch guns. No one notices those problems because most people are shooting carbine or middy gas systems.

PMC bronze is one, PRVI mostly, some golden bear, winchester white box and I think I had some wolf classic rolling around the range bag. None of which offered anything different. About 3-4 rds. then a malfunction.

My bone stock Colt Hbar A2 20inch barrel works just fine on Wolf, Silver bear PMC. Clean them Lube them and try different mags.

I did have a short stroke problem when I was shooting Tula crap out of old steel mag but when I loaded up a Pmag and re lubed her up she was up and running spitting some lube out but still running. Not the cleanest day of shooting Lube Plus Tula = muck and gunk..

I burned through all of the PMC ammo I bought on sale during the Magpul course. Zero issues with it.

Yep. Works great in short gas systems. Robb Jenson is the one that pointed out it chokes in Rifles.

I went and tried mine, and sure enough... This was a few years back. It's possible they've changed the propellant since.

OP

Not the same barrel length, however my MK12 runs all the .223 ammo I've put through it. The barrel is an 18" Douglas SPR barrel.

I bought about 800 rounds of PMC bronze sometime last winter. I shot about 600 of it through two different rifle length gas systems. No issues at all. So, maybe they have indeed changed their recipe.

I would hope so. It's really so easy to make ammo that runs a broad spectrum of gas systems.

These foreign banana's are constantly getting it wrong.

I just found two magazines with some of it loaded. We'll have to try it out and see.
