Good lower


Good quality and finish. Beware however that it does NOT work with Magpul Glock magazines. They either don’t lock in or lock so solidly that you have to use a rubber mallet to get them out

If you plan on using FM 9 mm upper. Don’t buy this lower! No LSBHO, FTF, LPS etc.

Good 9mm lower with LRBHO

by -

Flawless function with Glock OEM magazine. Brass, aluminum, steel, shoots it all. Only complaint, and the reason for four stars, is a short takedown pin. Short as in a tool must be used to push it through. You could swap that for an extended pin if you wanted to, though.

Mods needed to work with FM Products upper, but can be done with a dremmel and 10 minutes.


They will need to have a little modification to work with FM Products upper. There is a clearance issue with the bolt hold open linkage. You will need a Dremmel tool for a small modification to make the bolt hold open work. I have a binary trigger installed on mine and it works quite well.

Order this for my build because I like glock magazines better, it fits my faxon upper like it was made for it, they're absolutely no wiggleplay it's tight. Functions flawlessly, bolt stays back after last round fired, I have fired 500 + round with not one problem. This is a excellent lower and will be purchasing another one when available.

Buy it you won’t regret it!

This is a very nice 9mm lower. Built like a tank, excellent fit and finish. I wouldn’t change a thing about it!

Great 9mm lower


This lower works perfectly for my 9mm pistol build. No feed or extraction issues. It's a Spikes Tactical product so you know it's of great quality. It fits up great with my Aero Precision upper. Looks good...functions great. I would definitely recommend and buy again.

Works great


Fits perfectly with an Aero Precision upper. No issues at all. LRBHO works every time with Magul "Glock" magazines. I would highly recommend this lower.
