They work pretty good, but some of the mag holders are a little tight when using CZ factory 20 Rd mags. The 3D printing could be a little more precise too, but overall definitely worth it!
Just wish the delivery process was a little faster too
I have purchased the mag mount and the magwell mount for the firearm - both are top quality, I will be purchasing more items
Looks and fits great . . . wish the AR-15 vertical mount fitted my Sig Proforce MCX Virtus AEG similarly.
Shipping and delivery is way too slow, needs significant improvement.
Customer service is not very responsive either.
How can you have anything bad to say? It looks good, and works great. My favorite aspect ( yes, nerdy engineer here) is the thought that went into the mounting holes. The mounting hole slots are long enough to allow you to get it close, drill holes, install mounting screws, and fine tune for level before cranking them down. Nice design..well done Spartan.
Previously bought 3 other mounts from spartan and I liked them so much I bought a evo 3 when I saw they made a mount for that particular gun. Glad I did my safe room looks legit now!
