Help! Grendel Rifle not running

[Bill Alexander]

Start with the extractor. Look at the spring as this is the quickest thing to do. It should be a four coil regular unit with black insert. If this is correct then you either have a sharp extractor or incorrect geometry on the claw chamfer which runs the base of the case into the extractor tip.

If all else fails call me and we will see if we can get it sorted out for you.
