How much do they weigh?

Weight in ounces:

Carbine: 11.6 (Sampson)  13.0 (Troy)
Med Length (MX): 17.5 (Troy)
Rifle: 20.5 (Troy)

Quoted: Weight in ounces: Carbine: 11.6 (Sampson)  13.0 (Troy)

Weren't they supposed to be of similar design and construction?
Why do they differ much in weight?

Why does Troy weight more than Samson aren't they suppose to be alike?    If Troy weight that much I need to put mt M4 on a diet and go with DD or LaRue. 7.0

It seems Sampson does more lightening cuts to reduce the weight by an extra 2oz.

The Samson has channel cuts in the inside (underside) of the bottom and top rails.  There was WAY too much unnecessary extra material there.  It is now more inline with the KAC, DD, etc.  I received one of the first Samson MRFS-MX units made and covered this in my initial impressions post.

Also, those Troy weights are taken from the initial design (similar to Samson but w/o channel cuts), before they removed some of the holes at the 1:30, 4:30, 7:30 and 10:30 positions between the rails.  Their new design is likely to be heavier than before unless they compensated for the weight somewhere else (ie adding channel cuts on the underside of the bottom/top rails like Samson did).
