We sometimes see issues with the stripper lug size on their bolts. Some of their bolts are just fine and others the stripper lug is set too high on. Please check out our FAQs page to show where to measure on your bolt. Lug should be between .120 and .130. If you have a bolt that the stripper lug is high on please purchase our bolt mod service on our website and send us your bolt it is on $7.50 and that will fix the issue.
