Being in California, I installed an AR Maglock and king pin on my PA-10 Gen 3 rifle. It is not operating properly in the fact that I can not separate the upper and lower when depressing the kingpin with the bolt locked back. I’ve emailed ar maglock and they said that there needs to be space between the bolt carrier and the buffer tube. The bolt and buffer tube that came with my complete upper build kit fit very tightly. Does anyone know of any options or combinations that would allow the proper function of the kingpin
I have no idea, but wish you luck. Remember there is no standard with an AR10 like there is with AR15s.
