I am currently planning on purchasing a preban Bushmaster A3 with a 16" fluted heavy barrel. No carry handle, no bolt & carrier and no charging handle. I'll probably pick up the ARMS #40 at the same time.
Since I intend to use an Trijicon ACOG TA31 or TA11 (haven't decided yet) on a ARMS 19ACOG, I will need a flip down front sight. I wish to install a PRI front sight. I considered the Bushmaster flipper, but I prefer the PRI system.
Unfortunately, Bushmaster doesn't carry this line of products. Would it be possible for me to send the proper sight to Bushmaster for them to install? Or will I be forced to have another gunsmith do the installation for me?
What is the diameter of a h-bar 16" barrel?
Thank you for your time, I hope to do business with you within a month or so.
