It depends on what you want to do with it. Bushy's customer service is excellent. Their products are one of the best, and their M4 will serve you well for years to come. The M4 is a carbine, meaning short, light, rifle. A carbine is lightweight, therefore easy to carry in the field, the short barrel makes it ideal for confined enviroments like heavy brush, inside a vehicle, or in a building. It's negatives are that you sacrafice distance with the short barrel, while it will be accurate out to two hundred yards plus, accuracy starts falling off pretty fast after that. If you are after target work, competition, or long range varminting, a 20 or 24" barrel would serve you better. Bushy's M4 is a fun, lightweight and practical rifle, and also a very good entry level rifle if you are just starting out.
