Where can I buy the friction o ring that holds the mag in place on the Maverick/Dreamline mags.
Hi from South Africa!
Had the same problem a few days ago.
I used a BS004 (1.78mm Section x 1.78mm Bore) sized O-ring,
works well on my Wildcat MK3 magazine.
Got it at O-ring suppliers locally, but where to find it in the US
I won't know.
The size should make the search much easier.
