IHC "match" Garand and CMP Creedmoor ammo.

[Bob Seijas]

Some of the things armorers do involve fitting the stock precisely to the rifle... is there any bedding? Is the receiver really tight in the wood? Is there any wood removal?
Another is fixing the gas cylinder really tight... in a battle rifle there is a little play in the front handguard, but usually not in match guns. Is the guard glued or screwed to the lower band?
They sometimes try to reduce friction by polishing surfaces like the front of the bolt or the saddle of the op rod or even the sides and bottom of the barrel. Is there any evidence of stoning the finish off parts in the trigger group?
If none of these things is present, then probably the owner simply added some NM parts to try to make it shoot better, that's pretty common.
