If you have an A2 front sight post that is in need of removal, there are a few things that you will need to do in order to get it off. First, you will need to use a punch to drive out the old sight post. Next, you will need to clean out the sight hole with a drill bit. Finally, you will need to install the new sight post.
What is A2 Front Sight Post?
Assuming you are referring to an AR-15 style rifle, the A2 front sight post is the adjustable sight that is located at the front of the rifle, near the muzzle. The front sight post is used to help the shooter align the rifle with the target. The front sight post is adjustable for elevation, which allows the shooter to compensate for different ranges to the target. To remove the A2 front sight post, the shooter will need to first remove the upper receiver from the lower receiver. Once the upper receiver is removed, the shooter can then unscrew the front sight post from the barrel.
The Process of Removing the A2 Front Sight Post
There are a few different ways to remove an A2 front sight post, but the most common is to use a front sight tool. First, make sure that the firearm is unloaded and the chamber is clear. Next, locate the two set screws on the top of the front sight base. Using the front sight tool, loosen the set screws until they are no longer tight. Once the set screws are loose, the front sight post can be unscrewed by hand. If the front sight post is very tight, a small amount of lubricant can be applied to the threads to help loosen it. Finally, once the front sight post is removed, the front sight tool can be used to remove the spring and detent from the front sight base.
The Tools Needed?
Assuming you are referring to an AR-15:
First, you will need a front sight adjustment tool. This is a small, L-shaped tool that is specifically designed for adjusting the front sight post on an AR-15.
Next, you will need a small punch or an Allen wrench. This will be used to drive out the detent pin that secures the front sight post in place.
Finally, you will need a set of pliers or a vise. This is to hold the front sight post while you are driving out the detent pin.
