AR Parts for AR-15 and AR-10 Platforms
Browse AR parts for small-frame AR-15 and large-frame AR
configurations. From upper receivers and barrels to bolt carrier
groups, handguards, charging handles, gas-system components and
lower parts, Ballistic Barn carries components for repairs,
upgrades and custom configurations.
AR-15 Parts and AR-10 Parts
The AR platform includes multiple receiver sizes and component
patterns. While AR-15 and large-frame AR rifles share many design
concepts, their parts should not be assumed to be interchangeable.
Start by identifying the platform for your rifle, then select
components according to the specifications of that platform and
the individual product.

Use the parts directory below to browse the major component
categories available from Ballistic Barn. Several of these

Choosing AR Parts by Component Type
The upper receiver forms the foundation of the upper
assembly. Select a receiver intended for the appropriate
AR-15 or large-frame platform and compatible component
pattern.
AR barrels vary by platform, caliber, length, profile,
material, twist rate, gas-system specification and other
product-specific characteristics.
Bolt carrier groups vary by platform and cartridge family.
Check the individual BCG specifications for the intended
platform and caliber.
Handguard compatibility depends on the platform, receiver
pattern and mounting system. Large-frame dimensions can
differ among manufacturers and receiver patterns.
Charging handles are available in different sizes and
configurations. Confirm whether the product is intended
for an AR-15 or compatible large-frame upper.
Lower components include triggers, controls, springs,
pins, buffer-system parts, stocks and other components.
Compatibility varies according to receiver and platform.
AR-15 and AR-10 Parts Compatibility
AR-15 and AR-10 parts are not universally interchangeable.
Components such as upper receivers, barrels, bolt carrier groups,
charging handles, handguards and buffer-system parts can differ
substantially between small-frame and large-frame platforms.
Large-frame AR compatibility requires additional attention because
there is no single universal dimensional standard covering every
AR-10 or 308-pattern rifle. DPMS-pattern, SR-25-pattern and other
manufacturer-specific configurations can differ in receiver
dimensions and related component requirements.
Verify Platform and Product Specifications
Before choosing an AR part, confirm that the component is
intended for your platform and configuration. When compatibility
is uncertain, compare the manufacturer's specifications or
contact Ballistic Barn for help identifying the appropriate
product.

AR Parts FAQs
Does Ballistic Barn carry both AR-15 and AR-10 parts?
Yes. This AR parts category includes components for AR-15
rifles as well as compatible large-frame AR platforms.
Individual product listings identify the applicable platform
and other important specifications.
Are AR-15 and AR-10 parts interchangeable?
Not universally. Some components may be shared across
platforms, while major parts such as upper receivers,
barrels, bolt carrier groups, charging handles, handguards
and buffer-system components can differ. Check the
specifications for each product.
What types of AR parts does Ballistic Barn carry?
Available categories include upper receivers, barrels,
handguards, bolt carrier groups, charging handles, muzzle
devices, gas-system components, lower parts, buffer-system
components, triggers, stocks, braces and related AR
accessories.
Are all AR-10 parts interchangeable with LR-308 parts?
No. Large-frame AR components can vary by receiver pattern,
manufacturer and product design. AR-10, LR-308, DPMS-pattern
and other large-frame terminology should not be treated as
proof that two components are interchangeable.
How do I know whether an AR part fits my platform?
Start with the platform identified in the product listing
and compare the relevant manufacturer specifications for
your existing components. Large-frame AR parts require
particular attention because component dimensions can vary
among receiver patterns and manufacturers.
