The pictures from yesterday’s post.
Are from a AR-180B rifle. This part is the bolt hold open device.
You can see the difference between the AR-180B and the AR-180 with this next picture.
With The AR-180B some additional parts are required.
Looking at this next set of pictures you can see the difference between the two lower receivers.
The AR-180B was design to use as many AR-15 parts as possible. It was also a plastic injected molded receiver with a metal insert to act as usable surfaces for pins and wear points.
Here a few general picture of the rifle.
A close up of the upper and lower receiver. This picture showers the plastic molded lower and lack of a dust cover in the stamped upper.
Would an AR180B be worth grabbing? They’re kindof neat. I notice they mimicked some of the stamped parts in the plastic lolwtf, like piece on the front of the magwell.
I would grab it if the price is right.
