AR15/M4 question

[harrier]

I have an AR15/M4 and have a problem on loading a round into the chamber. The loading seems a bit rough but works OK. If I load a round into the chamber then extract it without firing I see 2 scores on the tip of the bullet. This is obviously caused by the tip of the bullet hitting the engagement slots as it enters the chamber. I have tried to smooth these a bit but it's still happening. So is it normal to get scores on the bullet tips? I also find that some bullet types are smooth and others are a bit rough when entering the chamber. The smooth bullets seem to be a bit shorter in length.

What weight bullet and build length? Do you see this with factory ammunition as well?

It happens with 3 different types of factory ammunition, Hornady, M193 and a bulk 223 (can't remember the name). The Hornady works fine.

That doesn't make sense to me!

Maybe the magazine is riding too low, is that possible?

Who built the rifle,

Reason I ask some years ago I had a Decade Corp AR-15/M4 Rifle built on standard mil-spec upper and lower with a standard T-handle rear charger, I had the same issue, to correct the problem I had the chamber area worked on by SGC they sorted it from then on no marks on the bullets and smooth feeding of every round.

Probably your feed ramps are damaged or incorrect.

The rifle is an American Spirit Arms ASA15.

Looks to be a mil-spec upper and lower as BamBam says may need the feed ramps worked on to smoth things out, like I had done on my Decade.

Looks to be a nice rifle....


American Spirit Arms now make side charging receivers...
