[QUOTE="Bart B, post: 690317, member: 5302"] Thanks, Gary. I believe the muzzle brake on M14NM's when TRW first made them was the brake's hole was too small; rain drops settling at their bottom (damned gravity!) caused vertical shot stringing. The US Army Marksmanship Unit spec'e the hole much bigger, reamed out the ones they had. . .no more stringing The USMC team shop did the same thing. As this was an "internal modification" it was within the DCM and NRA rules for service rifles. A few folks forgot this problem making M1A's into match grade rifles. I wonder how many bolt gunners know about this. Lots, now, probably from reading about it here. [/QUOTE]
