Nice.....the wrench tysdad linked is awesome.
Although a few good taps with a brass drift and then stake the castle nut should be good enough.
If your eyes are still good get some A2 style sights on that thing.
The RRA or white oak detach NM handle is nice.
I am not a big fan of the AR in general, although it's versatile nature and better than average accuracy you can get for short money lends itself to enjoying them.
Thanks. Ya I'll probably get some A2 sights eventually. I just had this scope laying around snd figured I'd throw it on.
I never really hated ARs I just enjoyed my SKS, AK, and Garand so much I never considered an AR until recently.
