Looking at purchasing an M4? Check this comparison chart out first
I came across an M4 comparison chart. Its compares the Colt 6920, LMT, Noveske M4 Light Carbine, Sabre Defense XR15-A3 M4, S&W M&P15 CMMG 16″ M4 Carbine, Stag Model 1, Bushmaster BCWA3F 16M, Rock Rivers Arms AR1251X, Armalite M-15A4C, Olympic K3B-M4-A3 and DPMS AP4-C.

The latest version of this chart can be found here on m4carbine.net

Saw some interesting manufacturers that I never heard of before – gotta check out their sites for catalogs and pics.
Thanks for the info, Steve
I’m interested in purchasing an M-4.
As I look over the chart the DPMS doesn’t appear to fare to well. I’m part of an outfit that is offering this firearm at a not so reduced cost as per your chart. The only thing that would be special is the engraving, and I would like that but not if it means a substandard piece of equipment.
All things being equal, what advice would you give on the purchase of an M-4 rifle.
Curtis, its just “M4″. There are so many options you need to decide what features you want, and then figure out what is available for purchase, eveybody seems to have long backorders!
