The Chainsaw will now be Noveske's forged product offering based on a hybrid of their Gen 1 and Gen 4 designs. They have modified the basic M4 look to match the Gen 4 aesthetic lines and smooth fit. Noveske will offer Chainsaw in three barrel lengths and two calibers to meet your needs. This product line, as its name suggests, is intended for hard and practical use. It will be Noveske's utilitarian offering, with the same quality and dependability, at a price point open to more users.
