I'm curious; Bushmaster makes a Bushmaster M-4 styled rifle that is listed at 6.7lbs here M-4 Sunset Carbine and at the Bushmaster catalog. However, their LE model is listed at 5.9lbs here: Bushmaster LE M4 Carbine . What exactly is the difference between the two? I thought they would be identical. Same goes for Bushmaster M-4 vs. the LE6920, the 6920 is listed at 5.9lbs here Colt LE6920 . LMT and CMMG also lists their M-4s at 5.9lbs. So, what am I missing? I thought the Colt, LMT, and CMMG M-4s would be heavier due to their larger, double heat shielded handguards. A further question: the MT6400C is listed at 7.1lbs at the Colt website- I thought it was identical to the 6920 besides the sliding stock, bayonet, and compensator.

NOTE: If all this seems nitpicky to you, well, then you're right! :)

For those that have one of the above rifles and a scale, could you post the stock (not buttstock, I'm talking unmodified condition) weight? Something tells me something not right with these weights. Thanks.

Those lighter weight rifles have 14.5" barrels vs 16.1,  the A3 w/ handle weights .4 lb more than A2 upper.  forget about the linked bushy, they are auto/burst weapons

I considered that, but the LE6920 has a 16.1" barrel + flash hider, and it has a detachable A3 handle and it still weighs 5.9lbs

Looking at the lengths between them the 6920 shows 2.1 " shorter. retracted length.  So the bushy may have a longer heavier stock, also the bushy likely has a full circle bolt carrier, the 6920 may or may not.  I'm sure for marketing purposes they will weight it as light as possible.


BTW  I am a friggin insomniac.

natedog,

the first link you offer is a rifle set up (20"er) and would for obvious reasons weigh in heavier.

The carbines (16s) you list all claim same weight and that is probably correct

The rifle stats should be compared to other similar set ups, like this one....Colt rifle

Note the link is to the Colt HBAR (aka: Heavy barreled mother)

Bottom  line.....

The difference in weights corresponds to the difference in length

Redfish, the carbine I'm referring to is about halfway down the page. Scroll down a bit.
