I shot Service Rifle during the 80’s &90’s. Clint McKee Sr., now deceased Fulton Armory Principal, built a number of Peerless M1A’s for me. All actions were “unlugged”, had Kreiger Stainless Heavy Match barrels, and McMillan Fiberglass Stocks with Black Pebble Grain finish in a heavy match pattern that appeared similar to yours. At the time, Clint had Mr. Charlie Maloney, a retired USA MTU armorer of great renown, bed Fulton Armory’s Peerless M1A/M14’s Using Mr. Maloney’s Proprietary “Full Contact Bedding” With Titanium Devcon and NO STOCK LINER.
Quit simply the best bedding jobs I have ever seen on any M1A/M14, all of my rifles have stood the test of time and high round count (3500-5000 rounds) without any failures (feed, extract, chamber, fire, etc.) and still deliver exceptional precision to this day.
It should be noted that I have steadfastly resisted the urge to remove the actions from their stocks, having done so only after 3000 plus rounds for a comprehensive cleaning and re-lubrication. It is my strong recommendation that you do the same, as rifles that are typically used in competition or casual range use can be adequately cleaned, lubricated, and have their gas systems maintained without removing the action from the stock.
I concede that this may not be the case with rifles used in combat or that see heavy field use, but better stock/chassis choices exist for the M1A/M14 system if used under those conditions.
As always, this is my personal experience only; your results may vary.
