First holographic and I have to say I’m enthusiastic.
My FM ambi complete lower has a “MIL-SPEC 6 POSITION” buffer tube. I compared it to the mil-spec buffer tube on 2 other guns and the FM is longer. Why is this?
In the pic you have FM on left, IWI Zion-15 on right. The FM was also longer than yet another supposed 6-position mil-spec gun I have.
I have a Mike 9 5” rear charger. They told me when ordering they would put RMB in it but I’m not sure if it has it. How can I identify the RMB components vs standard buffer/spring? Anyone have pictures or tips to identify? And if I need to manually ‘upgrade’ what parts would I get?
