Freaking amazing product!!!(get a compatible bolt first!) - Mean Arms Restrictive States EndoMag 9mm

I bought these because i do not like the look of Glock Mags in an AR. It arrived and it would only cycle from the left side. I was disappointed. I called MEAN ARMS and the guy (Tom) called me right back in like 5 min. Asked me to send pix of the bolt. I did. Next day his engineer emailed me and said the bolt i had was old PSA design. Said to get the FAXON. It arrived today. Chsnged out the bomt and went to the range. All i can say is my homebuild shoots better than my Sig. Totally worth it.
