I'm shopping for a 30 can and I'm interested in the idea of a reflex design. I like what I've seen about Griffins and their attachment brakes and I'm looking at the RECCE 7 and RSTA. Length on the rifle is more important to me than weight and the RSTA is only an inch longer on the rifle than the RECCE. Listed Db attenuation is quite a bit different and if the RSTA is much quieter then I think I'll probably go with that one. Going to be used on a 14.5" 308 carbine and a few bolt guns in 30 & 6mm, no magnums, no SBR, no FA. I'd really like to hear from anyone who is familiar with and has shot any of the Griffins, what do you like or not about them?
