Can you cut down a 5.56 spear LT to 11.5 and still have a reliable rifle?

No one really knows, as I bet no one has done it.  You can order an 11.5 barrel and swap it easily enough. Looks like you can get the barrels for about 760 from optics planet.

I'm Guessing he's asking because they are $760 Unless you can recoup a bunch with that 16" barrel that's steep but that's just a fact of life with the MCX.

I would imagine it should work, but may have to open up the gas port a little as well.

I'm into the MCX and learned that it's cheaper/easier to just buy the length/set up you want rather than try after the fact. Would love a longer rattler barrel and a tube to tuck my can but that would cost more than a whole new upper.

Between them already being a little overgassed and things like the mcx omega valve I doubt you’ll have much of a problem. Worst case you have to slightly open the gas port but I seriously doubt you’d have to.
Let me know who you use, I’ve got two barrels I’d like to cut down but after Morgan at class 3 died I haven’t known who to use for more unique barrel chops.

Best case it’s the same, better best case is you end up with a suppressed and normal setting instead of normal and adverse
