Best barrel especially for price!
This barrel is just what I was looking for to fit on my aero precision upper. The fit is so precise, and the aesthetics are sure to please. There was not a single deformity in the barrel when it arrived which is great to find for this price. Most places sell a throw away generic barrel for the price of this high quality precision barrel. The 6 flutes on the front and back are also flawless. The best part of buying from x-caliber is their amazing customer service. If you email them within their hours you usually get a response that day. Amazing! Thank you X-caliber for such a great product!

Outstanding Product and Customer Service!
I could not have been happier when I received and unwrapped the barrel for my Aero Precision M5E build.  Machining was perfect, fit and finish were top-notch, and it was EXACTLY as ordered.  The customer service was awesome too - the X-caliber rep I talked to was great, we discussed fluting options and I ultimately felt comfortable with the specifics of my order - 24" Cromo, heavy contour, 8" twist, in .243 Win.  If the attention to detail in producing my custom barrel is an indication, I full expect that this rifle will be a tack driver.  I will certainly be doing more business with X-caliber and will steer my shooting buddies to their products.

Great Customer Service and Outstanding Workmanship!
Submitted my order on-line then about a week later I second guessed my fluting selection from all the options available.  I called and spoke to a rep who was extremely helpful in helping me decide on the fluting configuration and without hesitation change my order.  It was obvious that he was extremely knowledgeable and passionate about X-Caliber's products and building barrels that meet customers' expectations.  I could not be happier with the end result, the barrel's fit and finish is absolutely flawless and fit my Aero Precision upper beautifully.  I also ordered the pepperpot compensator which was a perfect match to the barrel.  I don't think you could get a better experience, higher quality, and greater value anywhere else.  I will be coming back to X-Caliber for my next AR upper build and Savage re-barrel.
