How much accuracy? Anybody do a before and after test? It seems to me that a regular deer rifle has so many other accuracy handicaps, such as relatively light barrel, crummy trigger, walnut stock without bedding, cheap scope with slightly wandering zero and iffy adjustments, etc., that fire-lapping wouldn't make a noticeable and consistent difference. But if fire-lapping doesn't cost much and has a placebo effect ("now my rifle is accurate so I must live up to it!"), then go for it.
i also firee-lapped my colt h-bar, and a bushmaster dcm service rifle. i realize that a m-4 is not a match rifle, but they won't foul near as bad, and the bore will clean up quicker and easier with a lapped barrel. the barrel on my cle varmit is a 22"krieger, which is hand-lapped, the service rifles are as smooth as it is,patch goes right through them. ust was wondering if anybody does this???comments,,please
Easier cleaning is always a plus, but again, how much accuracy difference does a before and after test show? My stainless DPMS highpower AR cleans up easily enough, and shoots at least expert up to 600 yards (I don't but the rifle does), without fire-lapping. But again, if it makes you think the rifle is more accurate and doesn't cost much, okeydoke.
As far as fire-lapping chrome-lined service-grade M4 barrels, I don't see how that would make any difference, but I'll be glad to stand corrected if somebody can show otherwise.

Lots of people have, but for others, it's still a mental support that gives them confidence in their rifle/ammo combination. Not that I'm the world's expert on match shooting, but probably we spend waaaaay too much time picking at teeny little equipment improvements instead of working on sight alignment, trigger control, and wind reading.
When life gives you lemons, insert copper and zinc wires in them and repeatedly shock your tongue.
