AR-15 complete upper question (probably more for the Tula/WPA fans)

First off, this is not about your thoughts on Tula or WPA ammunition.

I finished my AR-15 lower build and I'm looking to buy a complete upper. My last upper was a mid-length Spikes and it functioned flawlessly with Tula and WPA. I'm not sure if it was because of the mid-length gas system, the ST-T2 buffer/spring combo, or both. My new lower build has the Spikes ST-T2 buffer and spring. All mil-spec, but not sure if that matters either.

I'm seeing some nice carbine length uppers out there and I'm tempted to buy one, but I am curious about the ability of a carbine-length upper to function well with Russian ammo.

Can you guys/gals give me some of your input on mid-length vs carbine-length and the effect on firing .223 Russian ammunition?

Thanks

I own a number of AR's and none of them are mid-length. I prefer the carbine length. I've yet to run into a problem with any of my rifles. I'm cheap as they come so I shoot mostly steel through my rifles... and have for about a decade.

That's not to say some rifles won't have problems with the steel. I know plenty of people have problems. I typically only buy Colt AR's but I've had good luck with my Stag rifles and my Windham rifles too.

The carbine system causes higher pressure, so it will actually help with lower powered steel ammo. My Spikes M4LE ran with steel just fine.

Correct.

I have several ARs, both mid-length and carbine systems and all run Wolf fine. The heaviest buffer I have in a middy is H1 and most are carbine weight for what it's worth.

Now, Tula is pretty much the only 223/9mm/45/40 ammo I won't buy. I had 3 malfunctions in one magazine with an AR that has about 3k through it with 0 malfunctions besides that 30 rounds of Tula---leads me to think ammo was the cause. I have a G21 that has thousands of rounds through it as well---0 malfunctions besides 3 out of the 50 round box of Tula I put through it. Again, leads me to think it was the ammo.

I know lots of guys like it but most of them seem to be shooting AKs and SKSs...
