Search function; an AR-15 door pin and E-clip can be modified to fit.

If they have it wasn't mine, looks like they used a dab of JBweld to retain mine. I am not recommending that as a fix.

I had to replace my extractor as it worked up and out, Bent and jammed the the works up against the top of the receiver. The correct extractor I purchased looked nothing like what they had in there.
That was at round 20.Round 35 the bolt hold open fell apart.
Is there some detailed instructions for this AR-15 pin and e-clip. (I searched but no luck)

What is the required modification to use the AR pin&e-clip?
No luck with search.

When I build a rifle for you they come standard, have for a few years, with the bolt securely fastened with either a roll pin or E clip.

so YOUR BM59 bolt stop actually works? interesting. I wonder why JRA doesn't do this...

Stop works fine, feeds good, no issues with reloads. If you really push on the mags they rock a bit.

Probably because your mag lip is sliding past the receiver apron where JRA made the apron to thin, common issue. You can, if you try, actually push the front of the mag up and through the receiver.

It looks like the rear of the mag lips bottom to receiver but the front location is a bit to far up away from the mag lips. It touches if I rock it and it does not go past (but yes it is idealy to wide and to short)
Well I chucked the bolt stop pin in the lathe cut a grove .010 deep and installed the e- clip. Easy peazy.
I'm kinda a shamed how much I like my crappiest rifle. The recoil impulse seams so much nicer than a m14 type rifle.
