In a thread started about 2 years ago, a poster going by "checkshoun" mentioned the Army's Marksmanship Unit tested 1911 barrels for accuracy in some sort of holding fixture. Sort of like a universal receiver, I guess, but one that uses 1911 barrels. Been thinking of building one to test barrels (and ammo) independently from the gun, but would like some how-to hints.
Anybody ever seen one - or seen a picture of one - or heard a description of one?
