Home Forums Hunting & Shooting AR and Tactical Rifles Building an AR

I may be wrong. I'm just using the math provided by the chart. It may be lower, but again it's a work in progress.

Adam

Well I shot the upper today. I was pleasantly surprised, it cycled soft and smooth with no hiccups. The brass ejected fine and didn't hit the deflector. This was with a CAR buffer, tube, and spring. I didn't have optics on it so I don't know the accuracy of the barrel.

Adam

Wow--quite the thread. Congrats on building it.

pic of the finished gun?

Please!

Well about that. I used a lower from an MP to test the upper. I am still waiting for my parts to come in from Palmetto Armory. In the interm I think I'll build a space stock as I just have a buffer tube and can't find any YHM lightweight thingys laying around.

I'll post pics as I progress and next week I'll have a scope on it to test accuracy.

Adam

I believe I'll wittle out a 80% in the next couple weeks or so

I have an upper with no stampings........it would make a nice pairing

I had to abandon the pink one for now, put too much paint on it on critical areas. But I present the Franken-Stoner.

Adam

Well I should have known that my SwarTasco scope was too good to be true, shot the AR today and the 4th shot the scope took a crap. It went from groups to patterns. I put my Leupold EFR AO scope on and a good cleaning so tomorrow I'll give her another go.

Adam

I would have bet it was too low myself

Ted,

It wasn't that it was too low, it was the fact the windage turret took a crap. It couldn't handle the 120MOA I needed to put on it to get to 100yds.

Adam

Well maybe it wasn't the SwarTasco. I went and shot it with the Leupold on it and it shot the same. I checked the crown out and sure enough one the legs on the carbon star isn't like the others. Telling me I dinged the crown at some point. So back on the lathe it goes. All well, it happens.

Adam

A poor crown will open up groups but something else seems out of square

I pulled the barrel tonight and nothing else is out of square. The gas tube isn't contacting the key, the rings are tight, the barrel torq'd properly. I mean it is a factory barrel and could be [bleep] to begin with, but I doubt it. I am banking on the crown and that little nick I see on the land.

Adam

Some goods reloads and presto.

Adam

Congrats! It was fun watching this one go together.

Yes as TC1 said it has been fun watching the progress.

Thanks again for the compliments. It was a fun project. I think I might have to make a few more of these things.

Adam

Finally got it out to 200yds.
