Definitely one nice .510 Texan...Do yo have the AOA kit ? Are you going to use a booster pump ?. I wanted to do same thing as you.....halfway there...lol
Yep… I installed the AOA kit, but broke tree top hats before tossing the massive hammer and building my own top hat. I gained a lot of adjustability, faster trigger response and a little over 70fps in the process. I’ve been considering the booster pump, but still undecided.
