Frequently Asked Questions

What tools are needed to install an Aero Precision bolt catch on an M4E1 lower receiver?

You will need a 1.5mm Wheeler wrench for the bolt catch screw. Additionally, a small amount of blue Loctite is recommended to secure the screw and prevent it from vibrating loose during use.

How do you properly install the bolt catch spring and detent?

The bolt catch spring and detent are placed underneath the enhanced bolt catch paddle. The pin of the bolt catch is then used to help align and hold these components in place as you thread the screw into the receiver.

Why is blue Loctite recommended for the bolt catch screw?

Blue Loctite is recommended because it provides a semi-permanent bond that prevents the small bolt catch screw from vibrating loose during the firearm's operation. It's strong enough to hold but can be removed with heat if necessary.

What are some notable features of the Aero Precision M4E1 lower receiver?

The Aero Precision M4E1 lower receiver is known for its integrated trigger guard, a flared magazine well for easier reloads, and a convenient drilled and tapped screw hole for the bolt catch, simplifying installation.
