I just purchased 2 Hellcat OSP one for myself and one for my son in military. My question is... Now they came out with the RDP version that I would of bought but I'm stuck with this unfired gun. My question is Can I buy the threaded barrel and comp along with the wasp to integrate it to my OSP or trade it in on RDP/??? Cost wise will I get hurt ? Most of the gun shops are rapeing buyers inflating prices so MSRP does not exist anymore. Please advise. Or what optics will fit on my hellcat Vortex venom ? holosun , shield what do you all recommend. I don't like the idea of taking the optic off to install batteries then have to re zero my sites. Is the cut an RMR base or is it preparatory to springfield arms mounting holes??
