Description
Anybody who's spent time behind an AR knows the bolt carrier group is where the crud lives. Carbon bakes onto the bolt tail, firing pin, and inside the carrier faster than a brush and solvent can keep up with. The Wheeler Delta Series AR Carbon Multi-Scraper is built for exactly that job, with a set of purpose-cut edges that pop that fouling loose so your rifle keeps running the way it should.
Every notch on this tool is machined to a specific part of the BCG, which is what makes a dedicated scraper worth having over an old knife or a screwdriver. It tackles 11 different surfaces including the bolt tail, bolt waist, bolt face, bolt lugs, both the large and small diameter firing pin sections, the interior of the carrier, and the cam pin. There's even a cotter pin removal point built in to help you break down the BCG when the firing pin retaining pin gets stubborn from gunk.
What the Wheeler Multi-Scraper Is Made Of
The body is stainless steel with a corrosion-resistant coating, so it shrugs off solvents and the harsh residue that comes with regular shooting. It's the kind of tool that holds up year after year on the bench or in the range bag without rusting out or dulling on you.
Keeping the Delta Series Scraper With Your Rifle
The real trick with this one is the size. The Wheeler Delta Series AR Carbon Multi-Scraper is small enough to stash inside the storage compartment of many AR pistol grips, which means the tool travels with the gun instead of sitting forgotten in a drawer. Toss it in a cleaning kit or keep it grip-side, and you've always got the right edge on hand.
A quick word of advice: this tool is cut for the AR-15 / 5.56 pattern BCG, so it seats on those dimensions and not on the larger .308/AR-10 carriers. Focus your scraping on the firing pin, bolt face, and bolt tail where carbon actually causes trouble, and you'll get the most out of it.

Frequently Asked Questions
What surfaces does the Wheeler AR Carbon Multi-Scraper clean?
It's cut to clean 11 different surfaces on the AR bolt carrier group. That covers the bolt tail, bolt waist, bolt face, bolt lugs, both the large and small diameter firing pin sections, the interior of the carrier, and the cam pin. It also has a cotter pin removal point to help you break the BCG down.
Will the Delta Series scraper fit inside my AR pistol grip?
It's designed to tuck into the storage compartment found in many AR pistol grips, so the tool can stay with the rifle instead of getting lost in a drawer. Grips vary in shape and internal room, so fit depends on your specific grip. If it doesn't ride in the grip, it's still small enough to live in any range bag or cleaning kit.
Does this scraper work on AR-10 or .308 rifles?
No. The notches on this tool are machined to AR-15 / 5.56 pattern BCG dimensions, so it won't seat properly on the larger and wider .308 or AR-10 carriers. If you run a .308-pattern rifle, you'll want a scraper cut for that platform instead.
Is a carbon scraper better than just using a brush and solvent?
For heavy, baked-on carbon it's a real time-saver, since each edge peels fouling off in seconds instead of going through a pile of patches and swabs. It's worth focusing on the spots that matter, like the firing pin, bolt face, and bolt tail, where carbon buildup can lead to reliability problems. The stainless coating holds up to solvents, so it pairs well with your usual cleaning routine rather than replacing it.
