[ARCHIVED THREAD] - 6.8 problem

Posted: 5/1/2008 10:40:20 PM EDT

I have a brand new 6.8 upper from stag arms. It shoots great but one problem HEAT. I shot 20 rounds (slowly) put it down, walked down to inspect the damage from my new gun, then started again. The only difference is that this time i rapid fired 20 rounds. After doing this i noticed that the barrel was so damn hot it burned my hand (not "owe it hurt" but "holy shit" and my hand had a bright red line in my palm from touching it). It was so hot that wiping spit on it caused it to steam off imediately.

Is this normal? I have never had this problem shooting my 5.56. I was shooting remington corelock 6.8.

just curious if i should be concerned

20 rounds rapid through anything but a bull barrel 22 lr. is going to cause a lot of heat.

bump for the morning crew

i know it should cause alot of heat, but my M&P can take 30 round dump and not be this hot. Is it normal because of the 6.8?

Is the barrel profile the same on your 6.8 as on your 5.56? If it is the same then of course it will heat up faster the hole in the middle is over a full millimeter bigger. You're also burning more powder.
