What can you tell me about this one?

With that serial number it certainly sounds like a Preban for sure ....

I thought NM front sites were .072 but I could be wrong here .....

I believe the OM THG designates a division of Winchester ...

Sounds like a nice weapon for sure and possibly a Marine match type shooter.

"Welcome Aboard" ....

Six

sounds like a winner.....

oprod is winchester. the barrel is saco defense. the trigger housing is essentially winchester. olin-matheson was their parent company back then. the front sight is NM .062 is a standard NM width.

what about your bolt?

Thanks for the quick answers. I checked the bolt and it is marked 7790186 66118 TT, which I believe is winchester. I was mistaken on the receiver being lugged. Looks like this rifle parts are all USGI winchester with the exception of the NM USGI Saco-Lowell barrel.

The stock is fancy walnut, oversize, and tiger striped. There is no cutout for a selector switch. Stock is not bedded, but fit is extremely tight.

How would one go about getting providence on this being Quantico armorer built?

if it didn't come with any papers when you bought it, i doubt you'll be able to do much. maybe try to track down the former owners? that's a place to start.
