Still in stock!

Your results a good bit off what I’ve experienced and seen with the 110 grain Barnes load. Take a look at post 1 and 10 here:

The Rattler gave up 300 fps to a 9” MCX and came in at around 1825 fps. While this is enough velocity to expand in soft tissue within 25 yards and after many barriers, I’m not surprised that it chokes on soft armor. FWIW, I’ve seen other articles on the load that quote around 1800 fps for the 110 grain Barnes load out of a Rattler and 2100 fps from 9” barrels; none as high as 2K from the Rattler.

I keep coming back to this. My analyst side keeps telling me a second 9” .300 upper with a LVPO would be a good capability extender for my Rattler.

I’m going to be ten minutes away from SIG today, and they have the uppers in stock…

… but not in the store, so I ordered one. They did finally have my MCX 11.5” 5.56 upper in, though. Saved me the shipping.

I’m trying to decide if I need this or not. My legacy MCX has both 16” 556 and 300 barrels, but no option for change unless I have them cut down. I picked up a rattler upper in 300 a while ago. The question is do I spend the coin on a virtus upper, getting access to all the parts/conversions, etc? Or wait for the rumored gen 3.
