Olympic Arms with Glock lower?

Ive got one in 9mm, upper receiver replaced with a 'straight' one as in an Armalite. I hate Olympic but this gun works well and I like it.

Ha ha ha!! funniest one liner I've read today, I am serious, I mean a 'straight' one, as in the freeken barrel not coming out at an angle in the upper receiver ;)
With the plastic handguards you couldn't see it, but with a freefloat rail it was not centered coming out of the handguard and the receiver rail was seriously out of spec.
The upper is standard except for the ejector 'sweeper' pin, simple mod. And I removed the bolt catch system, I hated that bare thingy.

But like I said it runs like a champ.
