Outside of SOLGW, Geissele, BCM, and Sionics I don't really see a need to go looking for important parts from anywhere else.
I don't know much about SLOGW other than what you've posted, but I use the other 3.
Geiselle stuff is pretty much all good, & I like to use it when I can, but most of their stuff (that they make internally) is & has been out of stock for 4-5 months or so...................think they got a big .guv contract, so their civilian business has been left to suffer, ditto to some degree for ALG, which they own.
BCM supply has been pretty good for the most part until just recently; haven't bought anything from SIONICS for a while.
