Good for the money.


Barrel appears to be in good condition upon being received. Item was protected properly for shipping. My barrel is missing the engraving for its twist rate and caliber.

Poor accuracy.


Barrel wouldn’t shoot well enough to sight the rifle in. Tried different handguards, torques, muzzle devices but nothing helped. Radical wouldn’t address the issue either.

Brass love


This barrel looks really good the quality in crafting is their and the coating is really good too. The accuracy is not their about 2 1/2- 3 moa with green tip and wide selection of 223. Wont shoot cheap steel. Got frequent stuck cases. Inexpensive barrel that only shoots brass. Go figure.

Great bang for your buck


I have one of these barrels that I purchased back in 2015. I did not purchase it from PA, but directly from RF. I've had none of the issues other reviewers describe. Accuracy is good as long as I'm steady - in other words, the barrel is generally more accurate than I am. It shoots everything I feed it - including cheap steel (never had a stuck case). Has all the engravings/markings it should. Maybe their QC has slipped over the years? I dunno. My experience with this barrel is that it's just as good as the BA barrel in my other build.

Good for the price

I have not used this barrel yet. It will be going on a 22lr build. At 58 dollars not really concerned about it being extremely accurate. I gave it three stars because they list it as a SOCOM barrel which it’s not. I knew that buying it but don’t like companies claiming something that it’s not. If I was building a 5.56 build or something along those lines, I would buy a different barrel. But for a 22lr build it will work fine.

Works Great

No issues with this barrel at all. It did take about 50 rds for break in, but it fires true. Would buy again and recommend for any one in need of a budget mid-length. Shipping was fast and it was well packaged.

Great budget barrel


This barrel holds zero and is properly gassed with corresponding budget parts (gas block, tube, BCG and buffer kit). For your first AR or one to practice on this is a great option.

Works Great.


Works Great , shoots just fine. The surprise was the dimple for setting the gas block set screw. More barrel makers should be doing this.
