Ok...thank you.

Sold. I will order one of their springs off their website. Additionally, does the material of the follower make a difference on function? Aluminum or steel?

Is keeping and using the OEM magazine tube spring on an aftermarket 7 round mag tube OK? Seems like the major consensus is to go with an aftermarket spring.

Got it. Thank you.

What about the Benelli OEM 7 round magazine tube? Any experiences to share on running that one on the M4?
