Upgrade to stronger materials with the Forward Controls Buffer Retainer Spring

Forward Controls saw that shooters needed a stronger AR-15 buffer retainer, and they fulfilled that need with this product.

The average factory buffer retainer spring on the AR-15 is made of low-quality materials. Over time, these wear out even from regular use, and it is not uncommon for shooters to experience jams as a result. Improve your shooting experience by maximizing your AR-15’s parts' useful life and preventing jams with this buffer retainer spring.

Made from 17-4 stainless steel, heat-treated to H900 hardness, and made with swiss machines, this is one of the strongest options available on the market. If you are building an AR-15, this is an excellent choice to contribute to a strong build. If you have modified an existing AR-15, upgrading with this part can help it function better with the other aftermarket parts you have upgraded it with.

Note on Installation

While some gun owners choose to have a gunsmith install their AR-15 buffer retainer, most people can do it themselves.

It can be a fairly simple install if you have the knowledge or experience of disassembling your AR-15, but it has the potential to cause problems if installed incorrectly.

If you are unsure if you can install this part by yourself, it is recommended that you arrange for a gunsmith to install this spring kit for you.
