The top one is my 20″ SPR type at about 11 lbs. I am going to change out the handguard to a lighter one just to shave off a pound or two.
The middle one is the new one I just built. It is about 5.5 lbs as is.
The bottom one is my wife’s and has Magpul BUS, Vortex Strikefire 2, a flashlight (200 lumen) and a Laserlyte green laser. it is about 6.5 lbs.
