First, this is the best M1A forum ever. I've got 300 rounds thru my Socom and notice paint & material being eroded from forward movement of op rod. Accuracy good but not as consistent as my Scout that has 5,000 rounds. Both have forward optics set @2.5x and use same 168 gr Hornady Amax. Both unitized gas system and bedded in wood stock. The Scout has a NM guide rod but the Socom had bunching up of op rod spring when NM guide rod installed....so it has standard rod. Any suggestions?
