CORE Warranty Claim Form

 
 
 

Dear Core Rifle Owners,

A warranty. What else about a product says as much about how highly a maker values their own work? It’s a mark of integrity, an assurance that the person who built it believes in it enough to stand behind it. Lawyers, legalese and fine print have no place in it. And we feel ours both stands on its own and speaks for itself.

“The rifle you have just purchased has the simplest, most plainly written warranty you will ever read. There is no fine print. There are no exceptions. This CORE Rifle Systems firearm has been manufactured and assembled with painstaking care and precision by proud US Veterans, trained by the best there is. If anything is not up to your standard, accuracy included, if anything goes wrong, gets bent, broken, cracked, misaligned, tweaked, snapped or otherwise, simply contact one of our professionals and we will work to make it right. If you are the 5th owner and the rifle has seen 40k+ rounds, it simply… doesn’t… matter. We stand behind our products and we take care of our customers. That is our promise and your assurance.”

We encourage you to take advantage of Core’s legendary, industry leading Lifetime Unconditional Warranty should you experience any issues in the function of your rifle. We would like to emphasize the importance of a thoroughly clean rifle for maximum safe and reliable performance. A clean rifle is necessary to properly diagnose any issues the rifle may have. If you would like to have the Core Warranty Department clean your rifle before diagnoses of the issue, we will happily do so. The standard cleaning fee is $35.00, if the rifle has extensive carbon build up or corrosion additional fees may apply. If you would like to send your rifle in clean, you will avoid any cleaning fees.

That is the Core Difference. See. Shoot. Believe.

Common Issue Resolutions

Typical Wear

It is perfectly normal for you rifle to have wear in certain places. The most frequently asked about places are the cam pin wearing on the upper receiver, the charging handle wearing on itself and the charging handle wearing the lower receiver. All of these are perfectly normal and would not require you to send the firearm in for service.

 

 

Steel Case Ammo

Steel case ammo is not necessarily good for any gas impingement rifle.  Tula and Wolf (the two foremost manufacturers of steel case ammo) are produced in countries with rifle industries predominantly made up of gas piston systems such as the AK-47.  These don’t cycle the gas all the way back through the rifle thereby keeping the dirty gas that is associated with steel case ammo out of the chamber.  The dirty powder will eventually erode the gas rings causing the bolt to lose the seal and permanently taking your rifle out of action until new rings are purchased and installed.  This is why our rifles don’t function as flawlessly as usual with steel ammo.

There is also a lacquer coating on steel cases that will gum up in hot chamber that will cause even more issues.  Yes, you can cycle steel ammo through our rifles but you must keep in mind that this ammo is very untrustworthy and dirty. This can cause you some cycling issues because we do hold tighter tolerances for our systems. It may require more frequent and thorough cleaning of the chamber , gas system, and BCG. I would recommend, not just with our rifles, but any firearm, to use a higher quality ammo.

 

 

Trigger Guard Installation

CORE® Rifle Systems will not cover broken or damaged receivers caused by trigger guard installation.


 

Safety won’t engage

While there is the possibility of a burr (a rough edge or ridge) on the safety detent keeping your safety from engaging, most of the time the issue is that the hammer isn’t engaged. If the rifle has been dry fired and the hammer is disengaged, that will cause the weapon not to go back on safe. Simply pull the charging handle and and that should reset the hammer to be able to move the safety selector.

 

 

Case Stuck in Chamber

Contrary to popular belief, your chamber needs to be cleaned before use. Our rifle chambers are match-grade which means they are tighter and are less forgiving with debris and dirt.  

When rifles are shipped out of our factory we have a protective coating in the chamber that protects against the possible long-term storage and debris from shipping.  This needs to be scrubbed and cleaned out or it will act as a suction/wedge that will prevent the rounds from extracting. 

The recommended tools for this job are a chamber brush and chamber mop. We recommend the Otis Cleaning Kits, they come with everything you need for cleaning and maintaining your firearm.  The chamber should be flushed after the brushing and coated with a quality gun oil.

If you have attempted to fire the rifle and an empty case is stuck in the chamber there are two ways to resolve this depending on the situation. 

REMOVE MAGAZINE BEFORE ATTEMPTING ANY TROUBLESHOOTING.

  1. If the bolt has ripped the lip of the casing off, you will first need to get the bolt locked to the rear. This is done by putting your thumb on left side of receiver on the bottom of the bolt catch, then pull the charging handle while maintaining pressure on the bolt catch. Once the bolt is locked back insert a cleaning rod down the bore to remove the casing.  
  2. If the bolt is still latched onto the round then what's known as “mortaring” will need to be done. ALL REGULAR SAFETY PRECAUTIONS SHOULD BE FOLLOWED!
    1. Close the butt-stock fully
    2. Point the muzzle to the sky
    3. While holding the handguard/forearm and pull down on the charging handle and pop the butt-stock on the ground with increasing force to dislodge the round.  

If you are confident the chamber has been thoroughly cleaned and you are still experiencing this malfunction then you may have a rough chamber that needs to be sent back.  Please fill out a claim ticket and we will get the rifle back here to be repaired.

 

 

Not picking up the next round (short-stroking)

If your rifle is ejecting the spent round that was just fired (or not ejecting and can be pulled out) but is failing to pick up the next round, crushing your round halfway up the feed ramps, also known as stove-piping, there are a few possible at home fixes.

The first thing to check would be your gas block.

To resolve this issue, simply push the gas block back up to the shoulder cut into the barrel, keeping the gas block as straight up as possible, and tighten down the two set screws underneath. We recommend some blue loc-tite to help keep the screws from vibrating back out again.

If your gas block seems to be in the right place and your rifle only experiences this malfunction every few rounds then it may be that the gas rings have aligned.

Normally the manifestation of this malfunction would be a stovepipe or the round getting crushed on the feed ramps.

This is something that should be checked with every rifle maintenance session and is easy to fix by un-aligning the rings.
