Snipers Dream

This barrel is awesome! I ordered one for an Aero Precision M5 build. This was the first rifle I have ever built piece by piece so I was a little skeptical about the first shot. I ordered all Aero Precision parts except for the barrel. Along with the Primary Arms 4x14 FFP Orion I was shooting 1.5 inch groups at 200yds on the Break In!!! Overall a great barrel. It is a beast and not light at all but that's how I built it. PA provided very fast shipping and I would HIGHLY recommend this for anyone looking to get into long range shooting.

Awesome barrel

I’m putting this barrel on my Aero Precision M5 308 build, it looks great and has a smooth finish at an unbeatable price.

Perfect and a blessing Thanks PA and BALLISTIC ADVANTAGE

Bought a barrel that was on sale at the time installed it nothing but problems. This one went on sale same day after I bought the other one. So I bought this one as well. Installed world of difference works perfectly no issues. Cycled a few unfired rounds through it minor brass damage from the feed ramps. The other barrel had MAJOR damage from feed ramps barrel extension and chamber. In short this is the way to go.

Great barrel

I slowly built my M5E1 Aero rifle up for about a year and a half. This barrel I got on sale in December of 2019. I got my final parts just before everything started to disappear in 2020.

This barrel will produce about 1.2 to 1.5" groups with plinking ammo and just out having fun. However, with match ammo I was able to find out that this barrel will shoot around the .5"(half MOA) 5 shot groups.

I would buy this again.
