AR-45 Problems And Fixes ( Part 2 A Closer Look )

Thank you for the updated video. Also thanks to Uncle Jim, I will contact Foxtrot Mike and see if they can do something. If not I will try your fix, thanks again for the close up shots.

Thank you for the update

Update
I contacted Foxtrot Mike and told them my issue. Even though they say using the Stern Defense Mag Conversion may void any warranty they still exchanged the bolt for me. Great customer service from a excellent company. Turn around was quick, they shipped it out the next day. Still haven't tried it, but cycling rounds through it with no hangups.

im actually having a similar issue with my new ar45 where the round fails to go into battery. Im not sure if I have the lip issue. Maybe you can help

This video was so helpful. I had Quarter Circle 10 BCG and couldn't stop the FTF. I tried both Glock and SMG mags. I would never have thought to grind the BCG. I was apprehensive at first and only ground a little at first. It got better. so i ground some more but left a hair. Now its perfect. I also had to polish the bolt face. My finger nail used to snag going over the firing pin hole so i flattened that a bit with the dremmel too before the polish. thanks for insight!

Thanks for the video. One question, may be dumb but I can't get my buffer past the buffer tube retainer when I'm trying to install. Because of the thickness of the 10 ounce buffer, it won't clear the retainer. Make sense? Thought maybe there was a trick to it. Thanks!

Dude......this just fixed my feeding issues. YOU ARE MY HERO

Same feeding issue u have. I will take a look at FM BCG and see if that could be it before I work on barrel

Do you have a parts list and the manufacturers of the parts + sources of these parts. I would like to try a build.

Think 10 oz with a 308 spring is to much ?

I have same feeding issues with kak barrel and kak enhanced bcg

Excellent. Good job
