    New AR-15 Semi-Automatic Standard: RCMP

    The RCMP have circulated a new memo to gun industry members advising them of a new AR-15 semi-automatic standard being used to classify semi-automatic AR-15 receivers from fully automatic receivers.

    Historically, the differentiation between fully automatic (M16) receivers and semi-automatic (AR-15) receivers has been the existence of a low- or high-shelf inside the lower receiver. Denoting the height of the milled pocket located behind the trigger mechanism, where a fully-automatic sear and disconnector would reside in a select-fire rifle, the shelf height has often been the primary indicator due to the machine work required to allow a high-shelf lower to accept full-auto trigger components.

    However, this latest memo from the RCMP looks to replace that aforementioned widely accepted international standard of shelf-height with an additional and nonsensical pocket width requirement. Early Colt AR-15 SP1 Sporter lower receivers featured a pronounced bump around the selector pin that protrudes into the lower receiver pocket, and according to the RCMP memo, “AR-15 pattern firearms which are not SP1 compliant risk falling into the prohibited firearm category as they can be easily converted to fire in a full automatic manner in a short period of time.” Due to the modern and almost universal standard of a lower receiver’s shelf-height being used to differentiate full-auto from semi-auto receivers so long, many manufacturers have forgone the needless SP1-syle machining of their lowers, and may now find themselves in the RCMP Firearms Program’s cross hairs.

    Odd choice of battles to pick, even if it is one of these weird internal memo things. Definitely more than a few of those in Canada.
