just do it yourself. Top rifle was done by me with $20 of rattle can in 20 minutes. Every range session it has been to people can't believe it's
a DIY paint job.
The internet never ceases to amaze me. OP specifically states “no diy”. First comment, “just diy”. FFS.
Custom Gun Coatings did this T4A. Bought it second hand. Don’t care for the color, but the work is top notch.
You could have it hydro dipped and then a clear cera cote finish over the top to make it more durable.
Lots of hydro dipping options out there and a clear ceracote finish won’t be expensive.
You could do it yourself though as has been suggested. It just won’t last as well as ceracoat.
