Colt LE6920 Barrel Profile?

AR/M4 AR General Discussion

I’m to lazy to take the hand guards off my LE6920, S/N LE691xx, to see what the barrel profile looks like. Caught this web page with a bunch of profiles

Is the LE 6920 more like the 14.5" M4A1 profile or the 16" M4 profile that is shown?

Thanks

The 6920 is the same profile under the handguards as the the 16" M4 depicted. The M4A1 is a heavier profile as spedified by SOCOM because their weapons have an automatic setting and they were burning up their barrels with mag dumps. The heavier profile increases the amount of rounds that can be fired at the automatic rate before the barrel bursts.

Thank you!

I bet that’s the difference between a LE6920 and LE6920HB

From another thread I caught

“LE6920HB - short run commissioned by Ken Elmore of SAW, limited to 300 units, identical to LE6920, however, the barrel has a “SOCOM” style HB profile under the handguards”
