All Things SUB-2000!
I have a new twist on an already great idea of using a Blackhawk CQC double stack mag hold to carry spare magazines. If someone has already done this I am unaware.
I took a UTG RS05S3 rail riser and cut the center out then replaced belt clip with the rail riser.
This gave me more options on where I could mount my spare mag.
One more thing: I inserted a setscrew under the tension spring so it would hold my mag tighter or you could use a piece dense foam rubber under the tension spring.
