It is a pretty easy modification, just not sure how reliable it will be until I get some range time with it.

The 30 round spring works but the original 20 round spring works will as well and is easier to load. Fyi this extension was designed to use with the Mk57 Banshee.
Use the factory 20 round magazine spring
did u have any problems with this at the range?
I know his video is old, but the problem is, that extension isnt compatible with the gen 2 magazines.. internally there is that peak that seperates the 2 stacks on the factory mag, and the extension is smooth.. it says it right on the cmmg website ans shows a picture of the difference
Is the cmmg good product?
bought the extension. never worked right. better to buy one piece mag. 20 round mag is enough anyway.
I am still waiting for my pistol to come back from FN, should be back in about three weeks.
Any issues at the range? How about mating issues with the USG style extension on MKII mags?
