Madcratebuilder..You kinda lost me on what will need to be done for serious competition?? Please expand on that Thanks
OK
Reamed flash suppressor. You ream the flash suppressor for better clearance of the bullet leaving the barrel.
Tuned gas system= Unitized gas system, weld or screw and glue are two ways of doing this. Read this.

You can upgrade the recoil spring and the guide that the spring fits on.

Sadlak stuff is second to none. Nice folks too.
Buying a M1A is just the start, there are a lot of tweaks you can do to get these battle rifles to shoot moa.
m14fireingline is a good source of tweaking information.
Standard vs Loaded
the loaded well have a NM barrel, either stainless steel or carbon steel.
.062 front sight blade
regular 1/2 moa rear sight with a non-hooded .052 nm aperture.
normal two stage trigger at 4.5-5 lbs, standard is 5-6lbs
SA does good trigger work.
I prefer a wood stock loaded with steel barrel, add another 1k (depending on the glass) in tweaks and you have a tack driver that can reach out to 600yds and beyond. 300-400 if you keep the iron sights. I couldn't make up my mind so I did both ways.
This is a all TRW usgi parts with NM sights, painted gi fiberglass stock, unitzed GC and reamed FS.
This rifle started with SA parts and a medium NM barrel. I reamed the FS, unitized the GS, NM fr and rr sights all the Sadlak parts and a 4.5X14 scope.
Some day I would like to build one based on this stock.
