Re: Thanks!!!...another question,
Replace it only if it fails or is obviously messed up. They have to be cut or ground off (at considerable risk to the bolt body). Most of the reports of failed bolt rollers (off some recent SA Inc guns) say that it causes cycling problems, but no real damage.Glockamolie said:How often should these be replaced??.
If it /One were to come off, it appaers it would cause considerable damage( broken op rod, and or to the operator??.)
