    Barrel Flex?

    I just received my DD 14.5 LW Middy upper with a 12 inch LITE rail. While fingering my toy I noticed that I can bend the barrel slightly by squeezing the barrel and rail together. I really doesn't take that much force to visibly see the barrel flexing torward the rail. Is this right? I like the weight savings on the liteweight barrel contour but It looks like my barrel will break if it is hit off of a wall or something. Anyone care to shed any light on this?

    Thanks

    I would like to know about this too. That was one of the first things I noticed after I put my Troy 13.8" MRF on my BCM 16" gov. profile midlength.

    don't squeeze then. both rail and barrel will bend toward each other, they are not made from unobtanium, that's completely unbendable. you have quite a bit of leverage that far away from where the barrel and rail both mount to the receiver.

    So your barrel is flexing slightly with a govt profile? That make me feel alittle better. I tried messing around with a bone stock BCM govt profile barreled m4 upper but the results were inconclusive.

    So its safe to say that ANY profile barrel will bend slightly when pinched with a ff rail extending out to muzzle?

    my noveske 10.5 flexes alot, it looked like my m4-2k was backing itself off or very loose. it scared the poop out of me while my buddy was shooting, as long as i dont get a baffle strike its no big deal though

    Well I figured that the barrel steel has to have some elasticity in it or else it would snap off the first time it hits pavement. We also have alot of leverage with the longer rails. It just seemed odd to me that it was able to bend that much.

    So do all barrels bend like that when bench supported out by the muzzle regardless of whether it is FF or regular plastic HG's?

    I noticed the same thing on my BCM govt profile mid-length. I actually noticed less flex with my DD 14.5 LT weight mid-length.
