If you own an ALS 50 BMG Upper Conversion purchased and delivered before July 2009, you are entitled to a bolt modification. ALS has identified a possible safety issue with some bolts manufactured before July 2009 which may cause the upper to fire out of battery. We are requesting all current owners of the ALS 50 BMG Upper Conversion built before July 2009 to send us their bolt and modified Jard hammer with spring (trigger is not required). We will then retrofit the bolt and return it to you free of charge. Do not fire your ALS Upper Conversion until the modification is completed. To participate in the bolt modification we will need you to:

1. Complete the repair form below and print page

Advanced Longrange Systems, LLC
3554 East Antelope Rd. Eagle Point, OR 97524
