About 2 years ago I attended Precision Rifle I at Thunder Ranch. Being the poor boy that I am, I took the best rifle that I had vs. buying a dedicated sniping (oh sorry, "precision") platform. This was a loaded M1A that has been bedded and unitized, has the NM barrel, trigger, flash suppressor, front sight. I did save my pennies and cry once in getting the Leupold M3 3.5x10x40 for glass. Having already wasted my money on the aluminum scope mount (the one that you are supposed to beat into place with a hammer) I got the SWAN/ARMS/Brookfield reproduction/imitation mount. Now only one problem. How does one get their eye socket to line up with the scope? The second day of the course we did a tower drill - run up the stairs, find your numbered placard on the board across the street - single load a round and shoot your placard. Out of 20 rounds I scored 4 hits. This cinched the issue. There is no such thing as a "Chin" weld. My group had been 2 MOA both days - just not what the match ammo and rifle should be doing. I may not be a Marine Corps sniper, but I have had enough training to be way beyond 2 MOA. Finally, one of the instructors takes me aside and we create a cheekrest. Another student had an old USGI sleeping pad that provided chunks of foam. White athletic tape bound it in place. Four layers finally did the trick. Viola! 3/4 MOA or less for the rest of the course! Now I have this horrid looking pile of green and white stuff on my stock. The quest begins for a reliable replacement. I find the Springfield Armory adjustable stock. JUST $450! McMillan has great stuff, but at not so affordable prices for this guy. Finally, sick of the mess on my rifle, I figured I would build my own imitation of the Springfield stock. After the second set of pin holes had wandered all over the bar, I threw in the towel on that one. I decided to try the approach suggested by a friend. After many, many cut, stitch, measure, fit, take out the stitching, re-stitch, etc. hours, I developed the cheekrest posted above. It is softer than a chunk of wood/fiberglass, and therefore more comfortable. It is stiff enough to keep your eye aligned with the scope tube. By changing the length of the hump piece, I can adjust the height to your specific mount/scope height. The lace-up system requires some focused attention to get on, but once you lace it up tight, it stays put. I find that this is better/tighter/quieter than the RRRRRIIIIIIIIPPPPPPPP!!!!! of velcro. If you don't like it, send it back for repair/adjustment/replacement. If I can't make you happy, I will give you a full refund.
