"perfect basic mag, use on my Krytac Trident CRB Mark II M
by Austin B. on 01/01/2023
"Bought these because they were cheap in price, wound up accidentally finding the best mags I’ve ever owned (no joke). The full metal body is extremely durable, the springs stand up extremely well and they feed every. Single. Gun that I own. They feed valken, black rain, Daniel Defense, TAPP m4 adapters and so many more that I’ve loaned to people. Only ever had issues with them feeding specific krytac replicas. My only complaint is the capacity of them, but for $6.50 a piece for the 10 pack I can stack them 3 deep for the price of 2 of the name brand mags. Good purchase and well more than likely work very well for you.

"I got the 10-mag combo but for some reason, I received the S&T brand, i don't know if they are the same or a collab or a subsidiary of them or what, but the mags are a little smaller than the regular(~5cm smaller in height),.

Build good,
matte finish, which makes them being put and taken out smoother for pouches and the rifle.

Smaller in height(if you put them in a mag pouch make a buffer piece in the button of the pouch so the mag sits a little higher and for a bigger grabbing space).
