So...... I built this here AR lower from a few bags full of RRA components. The Spikes Tactical upper should be here in a couple days.... complete but for one thing. A rear sight. The upper has a standard AR front sight, which I favor. I plan to plant a spare Eotech 512 on the receiver, with a folding BUIS behind it. I'm hoping for a good co-witness there.
So far, I'm leaning towards the Magpul MBUS, but I know there are folks here who are WAAYYyyyyyy more knowledgeable than I. Suggestions?
(Oh..... and more reports are in the pipe regarding the Liberty Ammo and the Doubletap pistol. It takes time!)
