-From the Crew-

“It has been a long road full of pot holes, endless miles w/o a GPS, ups, downs, lions, tigers, and bears. (Oh my indeed.) Through it all we have appreciated the patience we’ve received from you, our customers, as most of you have been on the ride with us from the very start of this adventure. We are thrilled to be able to offer our sandcutter carriers as complete bolt carrier groups with either our V2 or E4 bolts, both backing the lifetime guarantee. We look forward to serving you guys with more projects in the future and hope that the wait was worth it. Thank you for believing in us!”
