here they are

I just finished reading your post on aftermarket .308 parts and problems with mismatched gas and recoil systems. I bought a complete upper so I don't know the barrel manufacturer. KM Tactical had like 40+ on hand so I figure they bought out a liquidation or something, but maybe not. I don't see anything in the chamber that might cause this issue. I did clean the bore and chamber before the first shots. I was thinking the marks might be a magazine or feed ramp issue but I don't know that. .

I Built my first DPMS pattern lower and bought a .308 upper from KM Tactical at bargain basement cost. Yeah I know, ya get what ya pay for..... Went to range with 1 box "Hornady American Whitetail165gr. Interlock" factory ammo. I am using SR25 type magazines. Functions perfectly with mild recoil. Groups were more of a spread (3"@50yds) but I was shooting for break-in and function test not pinpoint accuracy. Anyways, I'm getting these dimples on all the case necks and some occasional dents and scrapes on the fired cases. You guys see this a lot? Does this need to be corrected?

Hi Guys, My 1st "black rifle" was an M16A1 in 1977 left over from NAM. I was so put off by that POS JAMM-O-MATIC I volunteered to hump an M-60 instead. I didn't even consider using or owning another AR until 2016 when the guys who run our 3-gun "zombie" shoot restricted the use of AK47s using Wolf ammo. Soooo, I bought an AERO Precision M-4 just for that event. I will admit I was pleasantly shocked at its reliability and accuracy. Turns out some bugs have been worked out over the last 40-odd years. Since that fateful day I have built an AR "pistol" and now an AR10 in .308 Win. My first choice was a .338 Federal but I had a set of .308 SB dies and no rifle chambered for that cartridge. Anyways, I have many questions about hand loading, mangled and dented fired .308 brass and building these things so they function.

I was looking for shared information on the net and came across this site in a search.
