Lots of discussion about the weight and everyone seems to post what their complete rifle weighs. That’s helpful to the point where someone needs to hit a 16lb restriction.
Here’s my take:
A1 Covert Chassis + Skins, monopod removed: 4 lb 8 oz
Buttpad, no spacers: 7 oz
Buttpad spacer, each: 2.6 oz
A1 Bolt, “308”: 12.2 oz
A2 Bolt, “308”: 12.0 oz
SA 6 Rd Mag, empty: 6.5 oz
Monopod: 5.6 oz
RRS ARCA Plate: 6.2 oz
ARC M10 QD-L 30mm mount: 8.5 oz
260 Rem barrel, fluted barrel and tenon, 27”, .920 muzzle with Area 419 adapter: 5 lb 4 oz
300 Win Mag barrel, non fluted, 27”, .850 muzzle, Area 419 adapter, 5 lb 1 oz
6xc barrel, non fluted, 27”, .875 muzzle, Area 419 adapter, 5 lb 5 oz
308 barrel, non fluted, 17”, .890 muzzle, Area 419 adapter, 3 lb 8 oz
450 Bushmaster barrel, non fluted, 23”, .920 muzzle, Area 419 adapter, 4 lb 6 oz
260 Rem barrel, non fluted, 19”, .875 muzzle, Area 419 adapter, 4 lb 6 oz
Add up what you’ll need, pick your rings/mount, add your scope weight and total weight of ammo and you should be good.
The A2 chassis saves about a pound, so hopefully someone else can post the exact weight with the bolt, buttpad, magazine removed.
