Not really, man - the real fix is to break it in with a couple hundred rounds of .308 Winchester commercial off-the-shelf ammo, with the upper receiver wet with lube, and get the function of the rifle down. After that, move to some military 7.62x51 ammo, and have at it.
These big fuckers need to be broken in, and parts meshed. Bearing surfaces on the BCG, inside the upper receiver, bolt lugs-to-barrel extension - all that stuff needs to be properly pounded into place, whilst wet with lube.
Hell, even magazines need to be broken in - don't go load your brand new 20-rd mag with 20 rounds, and expect perfection. Load light in the mags, break those bastards in, too.
These things ain't AR-15s...
