| I have been looking into buying an Bushmaster M4, but I don't know if I want an M4 barrel of a heavy barrel whats really the difference? |
Interesting !! can we change the poll to add this third choice ??? |
| The Army would disagree with most of you because the new heavier M4 barrel is 8 0uces heavier than the M4 weight and 4 ounces less than a regular HBAR of the same legnth.14.5.Why do they use it because of better heat resistance in sustained or full-auto.I dont have a full-auto but in sustained fire you can get a real high rate of fire and Id rather have a part that can take the heat for just a bit heavier.Hell Ive seen some tricked out M4 profile rifles that with gadgets weigh more than my 14.5 HBAR A2 with an aimpoint.I like heavier. |

Here is the breakdown: Guys complain about the weight of the HBar, but they only carry them from their safe to their car, and from their trunk to the range. So they insist on an M4 barrel, citing that HBars are useless without full Auto, even though M4 barrels are useless without an M203. Bottom line: Buy whatever barrel YOU personally like. Unless you are planning on mounting an M203 or using the barrel on a Full Auto lower (even at which, 30 rounds wont warp even a superlight barrel), or planning on taking your rifle on 20K hikes while also carrying a full ruck, than no barrel profile offers more of a function then the other. That being said, my personal preference is a Fluted Hbar. |
My personal favorite - Bushmaster 16" superlight: Bushmaster 16" M4:  Bushmaster 14.5" M4 (must have permanently attached muzzle device to be 16" or more)  BARREL WEIGHTS...
