Sphinx +3 Basepad
ZR Tactical Solutions
High quality and VERY durable. In addition to the added capacity, it really does serve nicely as an aid to pull and swap mags quickly. Will be purchasing more!
As a Quality Control Manager at a machine shop, I know Quality when I see it- THIS IS A GREAT PRODUCT! -Fit & finish is great.
ZR ships fast & these extensions are AWESOME! They fit perfect & the build quality is exceptional. I plan to outfit all of my mags with these.
