Re: GRSC CRS 1-4x and 1-6x ?
I've had one on top of my POF for about 6 months now and am completely satisfied with it. As mentioned the reticle is great, FFP, glass OK and surprisingly durable. I had a mishap with mine where it ended up taking about a 6' drop straight onto concrete while it was off my rifle. it ended up bent on the front edge of the tube but zero and functionality remained solid. Ed is a great guy, give him a call and tell him what your intended use is, if there is something better out there for your application he'll be the first to tell you. I intend on picking up one of the 1-6X in the near future. I'd suggest getting the Bobro mount for it from him too, super easy on and off and mine holds zero every time. If it applies to you, he offers a military / LE discount that makes it hard not to purchase.
