AR15/AR10

Choosing AR15 and AR10 Parts 

AR15 parts on this page range from receivers and barrels to handguards, bolt carrier groups, charging handles, and smaller components. Some are sold separately. Others come in kits or assemblies.

AR 10 parts are listed in the same category. With large-frame products, fit can depend on the exact pattern or receiver. The specifications on the product page are more useful than the general part name alone.

Types of AR Parts Available 

Main groups of AR 15 parts and accessories include:

• Lower receivers and lower components
• Upper receivers and upper components
• Barrels and handguards
• Bolt carrier groups and charging handles
• Gas-system and muzzle components
• Parts kits and assemblies

Products in one group are not always alike. Barrels can differ by caliber, length, or profile. Kit contents also vary, even when two listings have similar names.

What to Check Before Ordering 

For AR-15 parts, compare the details that apply to the specific component:

• Platform listed for the product
• Receiver, pattern, or manufacturer notes
• Caliber, length, or size where relevant
• Parts included with a kit or assembly

Similar product names do not always mean identical specifications. The same applies to AR parts that look similar in the category grid.

AR15 and AR10 Compatibility

AR15 and large-frame products often use the same names for components. The name itself does not confirm the same fit or dimensions.

Large-frame parts can also differ by pattern or manufacturer. For AR10 parts, check any pattern, receiver, or platform information given in the listing before comparing products.
