Rail Mounted Spare Magazine

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.

@Oldfart Cool mod for sure :metal: What muzzle break is that

Hey, Oldfart, nice setup, this caught my attention. I’m wondering where you sourced this part (Circled in red, picture below) and is it strong enough IYO with the 1 screw as a sling mount?

@Moosecall Looks like a D-ring found on the back of a picture frame.

That’s right I remember now.
When you pulled the bolt is it holding any internal parts that might move not allowing the bolt to go back cleanly without having to completely break apart to realign. Guessing I can refer to the parts schematic for the answer but though to ask as you have already pulled it.

I have not had any issues with bolt or internal functionality.
