BLACK HOLE WEAPONRY FREQUENTLY ASKED QUESTIONS
WHAT IS THE RECOMMENDED BREAK IN FOR BLACK HOLE WEAPONRY BARRELS?
1. Ensure barrel is clean - no oil.
2. Shoot 5 rounds of copper-jacketed bullets through the barrel.
3. Run a few patches with (non-copper removing) standard gun cleaning solvent.
4. Shoot 5 more rounds.
5. Continue this cycle (3&4) at least 3 more times (for a total of 20 rounds), with an opitmal total of ten cycles (50 Rounds).
6. Store Barrel with a light coat of oil. Patch oil prior to shooting.
Do I need to buy anything other than the barrel for .458 soCOM or .450 bushmaster conversion?
You will need a .458 bolt, but both cartridges, by design, only require standard AR15 buffers, buffer tubes and springs.
WHAT IF I SEE A BURR IN THE BORE AT THE GAS PORT HOLE?
Every effort is made to make sure that no burr occurs, but one is occasionally still attached to the underside of the gas port hole. In the event that a burr in the bore is seen, it can be easily removed from the bore with a cleaning rod and patch, or with your first shot.
DoeS BLACK HOLE WEAPONRY SELL BARRELS TO CUSTOMERS OUTSIDE THE UNITED STATES?
We do not ship our products outside of the United States.
DOES BLACK HOLE WEAPONRY OFFER MILITARY & LAW ENFOCEMENT DISCOUNTS?
Black Hole Weaponry offers a 10% discount to all active, retired and former military and law enforcement personnel. Please send and email to sales@blackholeweaponry.com for more information.
WHAT IS THE DIFFERENCE BETWEEN .264 LBC and 6.5 GRENDEL CHAMBERS?
Les Baer custom designed the .264 LBC cartridge to be completely compatible with the 6.5 Grendel, our head space gauges are marked with both cartridges.
The LBC has a .295 neck diameter, while the Grendel has a .300.
The LBC has a straight taper in the throat, while the Grendel has a compound taper in the throat.
The LBC uses 7.62x39 AR bolds with .125 head spacing, which is the standard head spacing for all AR rifles and most modern bolt actions, while the original Grendel used a Grendel bolt with .135 head spacing.
We originally made rifles with the standard head spacing (.125") which we called type I and a second head spacing (.135") only for the original Grendel which we called type II. Given the demand for standardization and lack of sales the type II head spacing has been dropped for 2017. We will manufacture a type II at your request.
DOES BLACK HOLE WEAPONRY MAKE SMITH & WESSON M&P AND ARMLITE BARRELS?
We do not make replacement barrels for the Smith & Wesson M&P 10, or for Armalite. In the past, Black Hole Weaponry has manufactured many kinds of custom replacement barrels for our customers, however, it has proven not to be cost effective to produce them at this time.
Does black hole weaponry have ballistic information on the cartridges they offer?
Yes! Please go to our forum and look up the cartridge of your choice.
WHY DOES BLACK HOLE WEAPONRY DISCOURAGE CUSTOMER BOLTS BEING SENT TO CHECK FOR COMPATABILITY?
WHAT ARE THE BLACK HOLE WEAPONRY FINISHES?
Black Hole Weaponry offers a Machine Finish, and a Satin Finish that is light bead blasting just enough to dull the machine finish to give it a matte look.
WILL BLACK HOLE WEAPONRY CUSTOM MANUFACTURE CHAMBERING TO FIT MY PERSONAL BOLT? CAN I SHIP IT TO BE INSPECTED?
PLEASE DO NOT SEND US YOUR BOLT. We do not manufacture bolts nor are we able to control the manufacturing processes of other vendors. Your barrel is one of the primary components of your rifle. Given the number of high quality manufacturers of bolts, seamless integration is generally the rule with our product.
UNDER WHAT CIRCUMSTANCES MIGHT MY PERSONAL BOLT BE REQUESTED BY BLACK HOLE WEAPONRY?
Your personal bolt may be required to manufacture specific non-standard "wildcat" chamberings. BHW cannot guarantee the performance or safety of your personal bolt after manufacturing is complete and your barrel is delivered. Additional shipping fees may apply.
WHAT IF I DO NOT SEE WHAT I WANT?
If you do not see what you want please CLICK HERE to drop us a note.
Due to the countless manufacturers of rifle bolts and gauges, it is extremely difficult to make all barrels’ headspace uniformly with all gun bolts and actions. Black Hole Weaponry uses go and no go gauges supplied by Pacific Tool and Gauge that are set to the industry standard. We also employ gauge standards for AR15 and AR308 bolts as measured from the base of the locking lugs (locking surface) to the bolt face. We have custom made jig fixtures to measure bolts and gauges. We also use a solid one piece gauge that eliminates the need for the use of AR bolts during the manufacturing process.
We cannot alter our product to match your personal bolt. If we were to alter our product beyond our standards for your bolt and the barrel/bolt combination were ever to become separated for any reason. There would be an issue of having a barrel on the market that does not meet accepted factory standards.
WHY DID IT TAKE SO LONG TO GET MY BARREL?
Black Hole Weaponry barrels are crafted to-order and involve many hand operations. Barrels are manufactured in batches of like kinds to speed the production times. Often given the volume of barrels in production, at any given time your individual barrel may be moving through the system along with the other barrels. Sometimes it takes more time than projected to get through the system.
