there’s a thread on here about the rt90 tripod
Imported RT90c 40mm tripod . Current and very thorough .
i could not bring myself to spend “rrs money” I original bought a Deamond from amazon for optics and lrf.
we started doing some night hunts realized I wanted a stout tripod for rifles. I bought one of the rt90c models, also from amazon ($272) after coupon that was offered.
WOW COULD NOT BE MORE IMPRESSES!
Everyone preaches the leofoto 364c. Which is clone/knock off of the rrs. The rt90c is also a knock off; also made of imported carbon fiber as the RRS and leofoto both are!!
i added a leofoto 75mm bowl head to my rt90c. after having it all in hand I would have bought. a qd arca-Swiss clamp and used the included 75mm bowl leveling base.
the ball head you already bought should also work on rt90. I had my Desmond ball head on rt90 before my “upgraded” leveling base showed up. Added some photos of each. Both will hold rifle. The 75mm bowl option seems to be what most guys are shooting off. I can get photos if you want anything more specific.
