Q5: May a repair change the dimensions or caliber of a silencer?
A: If alterations to a silencer would increase the overall length or change the diameter or caliber of a silencer, this is the making of a new silencer, as opposed to a repair. The new silencer must be registered and transferred in accordance with the NFA and the GCA. Alterations to a registered silencer that result in a minimal reduction in the overall length for purposes of rethreading are permissible as repairs. However, the reduction in length may not result in the removal, obliteration, or alteration of the existing serial number, as this would violate 18 U.S.C. § 922(k). If such a repair is necessary, the damaged silencer should be destroyed or returned to the registrant. If it is destroyed, destruction should be reported to the NFA Branch. Any replacement silencer must be registered and transferred in accordance with the NFA and the GCA. See Q2 and Q3 for further information on repairs.
Me:Thank you. I'm new to si co product. Didn't know alpha and beta can work together.
Si Co:They cannot, but the Hybrid is the unique exception as well as the Omega 36M as they have piston housings that are designed to fit the Alpha thread pitch.
