Apparently the M16 used to have a thin barrel, but they made it thicker. Now the M4 profile thins down the barrel under the handguards, and for the notch where you mount the grenade launcher. And finally, there is the new superlight.
I'm curious, because I'm considering getting a peban, but it has an 11.5 inch barrel with a 5.5" fs on it. I am going to have to buy a whole new upper, or have this one re-barreled, and I'm looking at the options. This barrel looks good, but I need to know what, if any, the downside is.
