Known Compatibility Issues:

• LaRue Tactical has a larger than mil-spec buffer extension in the lower receiver that interferes with the ARC Stock rails when attempting to collapse the stock.
• CMT Tactical UHP15 has a larger than mil-spec buffer extension in the lower receiver that interferes with the ARC Stock rails when attempting to collapse the stock.
• San Tan Tactical has built in quick disconnect sling attachment points just behind the takedown pin which block movement of the ARC Stock rails.
• LWRC ambidextrous lower has the right side bolt catch located in a position that prevents the ARC Stock from reaching its collapsed position. Modified version available at http://store.avguns.com/mvb-industries-arc-collapsable-pdw-stock/
• Spike’s Tactical ambidextrous billet lower has a right side bolt release lever that extends rearward far enough to prevent the ARC Stock from reaching its collapsed position.
• PWS MK1 MOD1 uppers (rifles and pistols produced from 01-01-13 to 12-31-15) were equipped with a carrier with added mass in the tail that requires the PWS specific smaller diameter buffer for the ARC Stocks.
• For all PWS MK1 MOD2 uppers and firearms, the carrier has the standard carrier tail bore dimensions and is compatible with our standard diameter buffers
