Can someone explain what the "detent balls" are that are being discussed?
If we swap the barrel out on an 870 does the firearm become restricted or remain NR?
Thanks.
The detent ball is something used in some Police and Wingmaster models of 870 to keep the magazine cap from "walking" off. Most new models including the Express and the tacticools do not use the detent on the barrel lug. They use a detent punched into the magazine tube to retain the magazine spring and stop it from putting pressure on the mag cap.
Swapping the barrel does not make it restricted. It is still over the overall length to be legal. If the barrel is built from the factory under 18" it is ok but you cannot modify your barrels to be under legal ie. a "sawed off" shotgun is no bueno.
You can email me at Nick@reliablegun.com if you have any other questions.
