    It should work, without the LRBHO function (as it is not a part on this upper receiver); however, we haven't matched one up to this particular model.

    Based on their specs, it should work; however, we haven't tried it so we cannot say for sure.

    Q Will this work with a .22lr bolt? answer now

    No, the C-4 side charger might though, depending on the make/model of the .22 conversion bolt.

    Once assembled the small “hook” end of the wire form in the upper should be pushed up by the follower of an empty magazine which will engage the bolt catch on the last round fired to hold the bolt in the locked position. If it does not engage, or engages before the last round is fired you can make VERY SMALL adjustments by SLIGHTLY bending the “hook” end down to lock faster or up to lock slower. They are set and function checked during assembly with brand new Glock magazines and our standard bolt catches. Because of varying magazine specs, magazine specs changing over the life of the product, different thicknesses of the pad on the bolt catch and other variables, this adjustment may be necessary with your specific parts.

    Yes, it will work, however, it would not offer LRBHO like our PC-Upper line would give you.

    It depends which PSA lower you're speaking of.  They have several variants.  They will fit this style of PSA Billet 9mm lower:
