Also putting one of them togeather. Priamary Arms also makes a FFP scope similar to the falcon for $220ish. I'm still undecided on mine. I probably would of allready ordered the weaver if I hadn't allready bought 30mm rings. I'm going to be shooting mine out to 300 yards if it will reach.
I've got a midway Vortex Viper in 4-16x42 that's I think I'm going to mount on mine for the time being. I'd buy another, but their out of stock at the moment. I've tried to convence myself on the Falcon, but the Vortex is just a few bucks more when it's on sale. Usually free shipping too.
From a few days worth of reading this is how I think they stack up. The midway Vortex viper is alot of scope for the money to find anything similar is going to cost $800 or more. The warranty is great too.
