I am consider building an "AR10" in 375 Raptor. Standard Aero M5 Enhanced build mostly, but with 375 raptor instead of 308. The purpose of the rifle would be for hunting, so I wanted to keep it to a reasonable weight. ( I know a bolt gun would be lighter, but wanted an AR10 project. I may rebarrel my Tikka to 375 raptor in the future.)
18" with midlength gas is what I was planning on for the barrel.
When I called X-Caliber to ask which barrel contour was lightest, the guy I talked said the socom heavy was the lightest they would want to go on the 375 caliber barrel. He said they would want the .875 gasblock instead of the .750. This was suprising because I have seen where people have gotten them in the SPR contour.
The socom heavy is .850 to the gas block, .875 gasblock, then .850 the rest of the way.
The SPR is .850 to the gasblock, .750 gasblock, then .730 the rest of the way.
I was hoping maybe some 375 raptor owners could chime in. Have any of you gotten the 375 raptor in their SPR contour?
Maybe X-Caliber stopped making them with the .750 gas block, because they got worried about wall thickness?
I think the SPR contour would be nice consider it would cut some weight and help the rifle balance a bit better. The socom heavy contour is around 3 lbs.
