Verified buyer2. It does what it’s supposed to do.
I could have spent less and just got an unbranded microbest but….
If I do ever have a problem I can call solgw and it’s resolved, not sure about calling microbest, and I like the stripes on this version of the bcg.
At3 is easy to deal with and got it out quick.
It’s like a tic tac. Can you breathe without a tic tac, sure, but I wouldn’t recommend it. Can you shoot without a solgw bcg, sure, but I wouldn’t recommend it either. 😆
Buy once cry once and enjoy.
