Instead of doing a caliber conversion get an upper! There are several in 5.56 & .300BO available!
I feel a bit better about where things are at. I appreciate the input. 556 is more affordable to plink with, and gives me something to work with while I work up to the 300 BO, and suppressor. It definitely checks all of the boxes with regards to what I was after.One benefit of the Rattler is it's a pistol... Later on when you buy different uppers they can go on the Rattler lower if there below 16" inches and you can take them wherever you'd normally take a pistol. The Rattler was my first MCX and I bought it knowing I couldn't afford .300BO rt off the bat but it's such an important gun IMO. What it's capable of is so niche it's almost priceless to me. You did good bro!
