Anderson Manufacturing''s M4 Carbine (AM15M416) improves on a familiar and reliable military spec rifle. Similar to Anderson''s Heavy Barrel Carbine, the M4 is chambered in .223/5.56mm and offering a 16-in. M4 barrel, optics-ready Picatinny rail, and front-mounted low profile gas block, also with a Picatinny rail. With its Magpul MOE stock and pistol grip and quad rail fore end, the M4 Carbine is also treated with RF-85, and features a hard-anodized 8625 F finish with a 7075-T6 aluminum receiver. Includes two 30-round Magpul magazines and a hard case.
In addition to the rigid quality controls of manufacturing, the feature that sets the Anderson AM15 Rifles apart from the masses is the proprietary RF85treatment allowing Anderson weapon systems to operate efficiently without“Wet” lubricant. In a coefficient friction test performed by Oak Ridge National Laboratory, the reduction of friction on all steel surfaces was reduced by 85%— without traditional “wet” lubricant, hence the name RF85. An RF-85 treated weapon cycles faster and more reliably, operates at cooler temperatures,experiences significantly less wear and, without traditional “WET” lubricant, doesn’t experience failures due to excess dirt and carbon fouling in the action.
Testing at Oak Ridge National Laboratories, the untreated rifle took 23% longer to cycle than the RF85 treated rifle during testing. Oil attracts dirt, sand, grit and other harmful particles. By using the RF85 treatment not only will the gun operate almost a quarter precent faster but will also last longer due to less drag and wear and accumulation of harmful elements is greatly reduced.
