About this stock
Midwest Industries Alpha Series M4 Beam Side Folder Stock Black is a stock for AR-15.
Match it to your receiver or buffer tube: AR stocks are mil-spec or commercial diameter, and rifle stocks are made for a specific action and barrel contour. Compare the fit details below with your firearm.
California note: folding stocks almost never work in California. Folded, the rifle drops under the 30-inch minimum overall length, so a folding stock has to be pinned open or replaced on either compliance method. See the California Rifle Compliance Guide.
