BCM m4 upper assembly alternative?

If you move quickly, there’s a lightly used Sionics NP3 BCG for $195.

Damn, that sucks dude. I have a SD 11.5” upper and a 14.5” URGI clone. Haven’t shot them yet. I pray they work. Did Geissele at least fix it and make it right or no? Were the Geissele’s recently built or from years ago during the Black Friday sale fiasco?

I always wanted to get a Centurion but they don’t pin the brake/flash hider (I know, I can get a gunsmith to do it, I’d just rather have the company do it). One thing I don’t like about the Geissele’s, is that for a $400 BCG, they give you lousy gas key staking. It probably works fine, but why not just stake it like a BCM or SOLGW?

The Geissele customer service was very good. I have no complaints in that department. They made things right. I have chalked it up to bad luck and moved on.
