Does your AR15 run on steel cased ammo?

My AR is a S&W M&P15 and Wolf ammo is all I have ever shot in it. I have heard that the S&W didn't like steel ammo. All I know is mine shoots fine with steel ammo. Don
 
Yes, AR Performance build (nitrocarborized, Wylde chamber, mid-gas). It digests Tula just fine, but I haven't run any of the other steel case stuff through.
 
All of mine except for two match grade chambered ARs. They get match grade ammo or brass only....Predator and Varminter

Shot 100 rounds of Wolf using a metal 40 round mag yesterday.....5.56 CMMG 16".....My Model 1, 7.62x39 AR only gets feed steel case ammo and seems to never miss a beat....
 
My stag feeds steel cased ammo perfectly. Bone stock Stag Model 2.
 
Olympic arms k30r... eats nothing but steel case... Brown Bear, Tulammo and loves it
 
I have 5 AR's of different makes and none will run on steel cased ammo. That's probably because I won't use it.:neener:
 
Yes... BCM upper on PSA lower, if my firearms do not shoot steel reliably then I sell them as that is mostly what I use. Had a Stag 3 that hated it.
 
Mine runs even the cheapest steel-case like a champ.

Spikes lower with Grizzly OPS-4 side-charging upper, carbine length gas system, bushmaster 14.5" barrel, Spikes H3 Tungsten buffer.

I've found that tweaking the buffer weight can help tune a rifle to better run steel case, in my experience (20+ AR builds).
 
Yes, so far mine has run flawlessly on Wolf and Tula FMJ. It's a 16" Rock River midlength, chrome lined barrel, 5.56x45mm chamber.
