X-Caliber Barrel Break-In

Procedure Guide

 

When breaking in your new X-Caliber Barrel, you should perform appropriate fire and clean cycles to normalize the bore surface. Each fire and clean cycle consists of a certain number of rounds fired (one to five) followed by a cleaning procedure (see below for reference), to be completed a certain number of times (1-25). These vary depending on the type of steel of the barrel, bore/groove diameter, velocity and pressure of any given round, etc. This is to be used as a guide. Since our barrels are hand-lapped, each barrel may break in a little differently. Some barrels may require more or less shots or cycles to break in than what is listed here.

 

416R Stainless Steel: Fire One Round then Clean: Do this 5-10 times. Fire Three Times then Clean: Do this 1 time. Fire Five Times then Clean: Do this 1 time.

4140 Chrome Moly: Fire Once Round then Clean: Do this 5-25 times. Fire Three Times then Clean: Do this 2 times. Fire Five Times then Clean: Do this 1 time.

 

 Example: For a 416R Stainless Steel barrel, you would fire one round, then perform the cleaning steps outlined below a total of five to ten times (shoot 1 round & clean, done 5-10 times) before starting the three shot cycle where you would fire three rounds and then clean as outlined below, then proceed to fire five rounds then clean, completing the break-in procedure.

 

Each Firing Cycle (1 shot, 3 shot or 5 shot) should be followed by cleaning the bore (see steps below for reference):

 

1.)    Using a one-piece, coated cleaning rod with a properly sized bore brush (wet with your favorite non-foaming bore solvent), carefully clean the bore from the chamber end toward the muzzle (3-5 passes is usually sufficient). If you cannot clean from the chamber end, be sure to use a bore-guide so as not to damage the crown or muzzle end of the rifling. Let sit 30-60 seconds before moving on to the next step.

2.)    Push a dry patch down the bore. (2-3 times)

3.)    Put a few of drops of oil on a patch and push that down the bore so as to leave a thin film of oil inside the bore.

4.)    Begin a new cycle: Fire your next round or rounds in your next firing cycle and repeat cleaning as necessary.

  

It is recommended to keep a written tally of your current step within the process so if you get distracted you will know where you left off.

 

 

Our ARs are tested with mil spec buffer tubes and springs. Any changes could change the way your AR functions. If any Non Mil Spec (Adjustable Gas Block, Heavy Buffer, Reinforced Springs, Light/Heavy BCGS, Piston Systems) parts are used, X-Caliber must be contacted.

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.

AWESOME Barrel and Customer Service
I had purchased a custom made 10 1/2 inch barrel for my AR-10 SBR that I had built and I can't begin to tell you how excited I was when it finally arrived and I had it installed. It fit like a dream and shot even better. I am a HUGE fan of the quality of the products offered and especially by their customer service, which I have found to be outstanding in every way and I couldn't be more pleased. I would strongly recommend that you purchase your barrels from X-
Caliber.

That kind of accuracy with a factory load!! well worth the money and the wait!! I cant wait to start reloading for this beast!

True Craftsmanship
Ordered stainless steel barrel, 30 caliber chambered in 308 Win., 18'' barrel length with mid length gas system, cryogenics and RCA bolt carrier group. Worked very well with Smith & Wesson M&P 10. Extension fit very snug into receiver witch is a good thing. Shot 4 clover leafs in a row all others were 3/4 inch groups and less @ 100 yards off of caldwell AR shooting bags.The RCA blacknitride BCG cleaned up very easily no carbon build up wiped clean with a paper towel used CLP just for the heck of it. Thank You X-CALIBER
