Archived [ARCHIVED THREAD] - head space and bolt gap
Posted: 10/16/2003 9:06:57 PM EDT
Going to a gunshow this weekend with another G3 type on the list.  Whats the range on the bolt carrier gap (headspace)?  Just want to check before I buy so I can at least eliminate that from the list of probs before I buy.

Thanks

Bolt gap should be between .1mm to .5mm or .004 to .020 inches.  If it's below .007 inches I would replace the rollers with +4s.
