Lakeside Machine manufactures the following models of
Razorback rimfire beltfed conversions for the AR15/M16 type
family of firearms. Prices and availability can change at any time, so
please call to verify stock on hand. If you wish to have a variation of any
featured Razorback, we can make that special model for you. Each Razorback
comes complete with buffer system for a carbine or rifle stocks, a Lakeside
exclusive reduced power hammer spring, a 50 round belt, and operators manual.
Lakeside Machine does not manufacture complete beltfed rifles. You will need a
lower receiver, a sight, and ammunition to have a complete system. Each
Razorback is test fired at the factory using 22LR CCI Blazer ammunition.
Lakeside recommends a full round nose bullet profile of 40 grains in weight for
the most reliable function. Choose from various barrel lengths in stainless or
parkerized steel. Conversions can be purchased for semi-auto AR15 rifles,
registered full auto receivers, AOW, SBR, and pistol designated lower
receivers. Accessories can be purchased like extra belts, links, feed box
systems, spare barrels, cycle rate manipulation systems and more! To
make the transition from .223 center fire to 22LR beltfed is easy>>
