I love them but the rail did not fit my Christian synthetic stock had to do some retro
I love my Tricer-X1 and Tricer-AK. The tripod is super solid and the head clamps down tightly on both picatinny and ARCA.
I shoot rifles from it and use it to film when I forget my camera tripod, as my camera also uses ARCA for mounting.
Side note: Don't attach adhesives to the legs of the X1. They pull the finish off. No biggie, this thing wasn't meant for that. Shoot guns, spotting scope, film and you're golden.
A really a great addition to my NRL Hunter light weight build.
