Just curious but how does the bullet button work? the pic does not look like a fixed mag?

A bullet button looks outwardly like a regular magazine release that you could press with your finger but doesn't connect directly to the magazine release lever on the other side. Instead, it is hollowed out for a larger spring and a nut that goes inside it that binds against the spring and threads onto the magazine release lever. Once this nut is screwed fully onto the lever it is deep enough that only a tool may be used to depress it. A bullet tip is considered to be a tool and can reach deeply enough into the recess in the bullet button in order to manipulate the magazine release lever.

I just built my first ar 15 lower and was looking at model 1 sales. They have some nice prices. Im thinking xm177, but they have lots to choose from. Nice work by the way.

bcjwriter,

A friend of mine built an AR-15 using a Stag 20in. upper
We took his rifle out to the range and the STAG performed very, very well.

I also built a 20" gov. profile rifle, but I used a BCM 20" upper and love it, love it, love it!

Both are great choices IMO.
