If you are going to work on your own weapon either as someone new to customizing a gun or someone with extensive experience, a great option to consider is one of the AR 15 kits.
There are both upper and lower AR 15 kits, each designed slightly differently depending on the manufacturer. There are several reasons why these kits are a good investment, just considering the following factors will help to understand their value.
All In One
When purchasing AR 15 kits, there is the definite advantage of getting everything you need in the kit. This is ideal for those who are doing this for the first time or as a hobby as opposed to working on weapon customization and repair on an ongoing basis.
While a gunsmith knows each part and what will be needed, most people don’t know all the components and parts that go into upper and lowers. Springs, bolts, pins, retainers, screws and other components make up the assemblies. Missing one or ordering the incorrect part when trying to piece it together can result in delays and additional costs.
Ease of Use
Most of the manufacturers of kits make them easy to use for gun owners with any experience level. This even includes color coding of the kit by some of the top suppliers. With the color coding, it is clear which parts are used in different sections of the upper and lower, helping to avoid confusion and difficulties in getting the project done.
Finally, by using a kit, you are sure that each of the parts is designed to work with the weapon that matches the kit. As parts can look very similar between weapons but affect performance, this prevents common mistakes of incorrect or incompatible parts.
