Re: Cmmg vs Tactical Solutions M4 22 dedicated upper
I picked up the Tactical Solutions AR-22 LT upper a few weeks ago, and 8 Black Dog Machine magazines with the stainless feed lips. Don't know if it was the ammo (Federal 550-round brick, purchsed in 2008) or something else, but it stovepiped like a Motherf**er.
Admittedly the following are possible:
- Problem with the ammo. It was purchased near the end of the "Obama fear craze" when ammo prices doubled so Federal could have been putting out substandard ammo.
- Weak AR hammer spring. I mounted it on a cheap ShARps lower with the worst trigger I have ever pulled so the spring could be weak.
- Not boken in action. I cleaned and lubed it before taking it out, but it was the first time shot.
It's now sitting at the back of the safe due to other rifles taking up my attention lately, but after checking out the .22 Rimfire competition last night at the local gun club as a spectator, I think I'll drag it out and troubleshoot it. At the very least I have a warranty to rely on.
As for accuracy: at 50 yards with an Aimpoint CompML2 the upper is extremely accurate. I was easily 1" with an entire 26-round magazine. Mind you: that Aimpoint is a non-magnified red dot, so for accuracy I'm pretty happy with it, especially considering the price.

Edit: I just realized I used the wrong term. I typed "stovepipe" when in fact the rounds completely failed to fire. In my mind, stovepipe is a round that fails to eject and jams either in the chamber with the next round or within the upper receiver, partially ejecting.
