I have one PWA, A-1, commando lowers with A-3, T numbered LAR flat top upper. The fit on this receiver set is very tight. No need for any accu wedges. Upper and Lower have been gun-koted flat black to match for color.
Looking to trade straight across, one set (preban PWA/LAR) for one set, of post ban, stripped, Knights SR 15 flat top upper and lower.
Here are pics of what I am looking for
