So You've Decided to Build an AR-15
Now that you’ve chosen to explore the AR-15, you will need to decide what kind you want to build.
We have designed builds around the Aero Precision M4E1 platform. This is one of the best AR-15 platforms available. If you have not already done so, please check out our Platform article in the Design section for a detailed analysis of the M4E1 and other Aero Precision platforms.
We have assembled kits for small frame AR carbines and rifles.
Carbine
A carbine is the most versatile AR design. It is not as compact as a pistol, but it is still very capable of close quarters engagement of targets. At the same time, it can reach out to moderate distances, without the bulk and weight of a rifle. A carbine will generally have a buttstock that is on-the-fly adjustable for length of pull, which is really the part that makes this versatility possible. A carbine will be heavier than a pistol, but lighter and more portable than a rifle. A carbine will be longer than a pistol, but shorter than a rifle. This is your Goldilocks gun in most scenarios.
Rifle
A rifle is designed for long range target engagement. Generally, the rifle will be built for stability and for maximizing the velocity of your cartridge. You will typically find a fixed buttstock, often with multiple points of adjustment for length of pull, comb height, butt plate angle, etc. This adjustability helps the shooter tune the rifle to his or her body geometry, contributing to ideal body positioning and alignment, and making it more comfortable and ergonomic for long sessions on the gun in the prone or supported position. Rifles will generally have longer barrels than their carbine counterparts, which can have a significant impact on weight. The added weight of a rifle is generally acceptable, as the ability to engage targets farther away reduces the importance of portability and maneuverability.
