(add $3 for insurance). Payment preferred by Paypal. You cover the fees or pay by Paypal with bank account or send as gift. USPS Money Order is okay too but I don't ship until it clears my bank (two days usually).
Manufacturers description: The ARMS #40LSP is identical to the ARMS #40L but it utilizes ARMS' same plane aperture system. This aperture set allows the operator to choose between large and small apertures without worrying about them being zeroed to different ranges.
The small aperture can also be removed if the user desires the larger CQB aperture only.
