Semper Fi! Wes!
Yes! I served back in 1966-1970.
My MOS was 2532 Radio Relay Operator
By default a 2531 radio man on occasion.
All of us were 0311's:-laf!
My gunsmithing interest was developed as a kid.
The Corps did not see the need to develop my interests. Just what their critical need was at the time.
I went to Gunsmithing School after I was discharged from active duty.
I love to build and shoot them rifles! However, there are a couple of posters on TDR that are head and shoulders above my poor skills

!
The rifle in your link looks like a real winner.
A Gary Schneider Barrel! They are also used by Tubb in his T2K match rifle built by McMillian Bros. . Good stuff there!
I went with a 1-11" twist in mine as a compromise twist which will still stabilize the 175 Gr. Sierra Match King in cold temperatures and still sling out the lightweights like the Barnes 130 TTSX at 3200 FPS for deer and coyotes

!
Been thinking about a McMillan A-5 stock for another build down the line. Have to finish up a few rifles in the planning stage.
I would really like to build a . 300 WSM Varminter and an F/TR class rifle. Dont know what cartridge I would use for the F/TR rig, as yet. Probably the good old . 308 or even a . 30/06

.
Dont be jealous! You get to shoot more than I do:-laf!!!
Send Greetings to Your Son. SEMPER FI! Thanks for your Service! I know he loves his job! That is a requirement when building surgical tools for those that will use them in harms way!
