I think you need to really start calculating the weights though. The Vortex Spitfire 5X HD Gen II is 10.6 oz. but the 3X PA Prism is 18.4 oz. (due out in August apparently). Primary Arms 1-6X or even the 1-8X are 16.9 oz. The mount for a scope will also be likely heavier. But, the versatility is something to consider, as is what you plan to use the rifle/optic for.This might be unpopular opinion, I don't like LPVOs in most applications. Think about how they are often used—either at minimum or maximum magnification. Meanwhile you are carrying all that dead weight, especially detrimental when the XCR is on the portly side to begin with. The 8x in this example, is overkill for 5.56. For sport and defense, light weight and high mobility should take priority. And going that route isn't necessarily expensive. Vortex just came out with a compact 5x around the size of a Trijicon MRO (there is a 3x too and PA will soon have their version of it with ACSS). This Vortex 5x even has integrated mount on top for unmagnified reflex red-dot. Or, you can just run offset iron sights. If you go with the 3x version, you probably don't even need irons until the optic fails. Marine and Army grunts run like this just fine (i.e. ACOG + standard AR sights).
LPVOs with max 8x make a little more sense on a DMR rifle, like a XCR-M. So, you need to buy a -M now and move your scope to that.
O/T: Trialed bigdaddylimited recently for giggles. It's legit. 1-month trial for a buck, plus 10% tax on cart total at check out (allegedly local county tax of theirs). $1k scope sold at Optics Planet (already under MSRP) for little over $700. Cancel membership before the trial is up. Re-up on trial the next time you need something on the big ticket side.
Don't forget the mount. I kind of want to play with the new vortex/PA 3x and 5x micro prisms (spitfire HD gen2). If only they made a micro/t2 mount for the top. Still narrower fov than the Elcan unfortunately.Yeah, but at that point, you're talking more weight than a 1-8X24mm if you're talking about the PA 3X Prism.
