Tapping M4 mags

[Airsoftgiraffe]

Hi guys,  

I’m thinking of getting the Hpa valve adaptors for my gas mags so I can use HPA.

I have tried the search function. It failed finding anything.

just wondering if anyone has done this and are the results worth it.  
 

I’m just frustrated getting frozen bolts.

HPA works extremely well, but lots of sites don’t like it as it’s too easy to cheat the chrono

Yes, I hpa tapped my mp7 mags. no problems with mag swaps really,as im not in that much of a rush lol. In fact sometimes i just use the one mag and speed load it!

The armorer works drum mags, when tapped are also a good option for more capacity.
