    The 556R is actually one version that I don't have, but I'd like to have. From top to bottom, the ones I have are the 553R, 556 Classic SBR, 556 Classic, 551LB and 751 SAPR with 17.8" barrel.

    So, the micro gas system and mini upper?

    Buried mini gas needs standard upper to be buried.

    Mini gas length with mini upper is an exposed gas block.

    Micro gas in a mini upper will be buried but you're going to have exposed barrel. Not in a good way....my opinion.

    I specifically want the 9.5" exposed barrel. It will be sort of like the 553R shown above.

    Then the mini upper with micro gas is what you want.

    I have a 552LB and a PE90 on order as well. There are definitely some fun times ahead.

    They Gen 2 556R shoots nice. Shockingly accurate for 7.62x39 (with Wolf even). Since it is one of Sig USA's earlier attempts at making rifles, it feels a little flimsy. The Swiss-style handguard rattles when new. I made shims from a beer can and JB-weld'ed them to the handgaurd to fix that. Not pretty, but not visible once assembled. The XCR-L is a tank compared to it.
