Bolt Carrier Conversion Service

Adding to cart… The item has been added

Bolt Carrier modification service. You send us your semi automatic Scar(tm) bolt carrier and we will install a removable and user-serviceable roll pin trip surface to allow the use of a Rare Breed FRT trigger, M16 fire control group, or the original Belgian factory Full Auto FCG.

Please allow 5-10 business days (a business day is Monday-Friday and does not include weekends or holidays) from when we receive your carrier to perform the conversion.

After purchasing, we will email you instructions and a form to send in with your carrier .
