AR-15 – Gunsmith Kit – Builder & Repair Parts – Luth-AR
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Luth-AR Gunsmith AR-15 Parts Kit is a bench-ready parts assortment for assembling, maintaining, customizing, and repairing AR-15 rifles. It includes a deep spread of common small parts, springs, pins, bolt components, gas rings, extractor parts, firing pins, cam pins, crush washers, and a Delrin punch.
This is not a single lower parts kit. This is the “save the build, fix the rifle, replace the tiny spring that launched into another dimension” kit. If you work on ARs, this is the kind of box that keeps the bench from turning into a scavenger hunt.
Fitment
- Built for AR-15 platform maintenance, assembly, and repair.
- Includes common AR-15 lower, upper, bolt carrier group, charging handle, dust cover, and gas-system small parts.
- Includes .223/5.56 crush washers for compatible muzzle device setups.
- Individual part compatibility should still be verified against the specific rifle, receiver set, bolt carrier group, and build configuration.
Does NOT Fit
- Not a complete rifle build kit.
- Not a complete lower parts kit for every possible AR variant or proprietary receiver setup.
- Not intended for AR-10/LR-308 platforms unless an individual part is specifically compatible.
- Do not assume proprietary AR-pattern rifles use standard AR-15 small parts.
What It Does
- Stocks the bench with common AR-15 replacement and repair parts.
- Helps support multiple builds, repairs, part swaps, and maintenance jobs.
- Covers commonly lost or worn small parts like detents, springs, roll pins, gas rings, extractor parts, and firing pins.
- Includes a gun mat to help organize parts during bench work.
Why It’s Worth It
This kit makes sense for armorers, builders, shops, and serious AR owners who hate stopping a job over a $1 spring. It is not cheap, but downtime is worse. A stocked bench beats digging through mystery bags like a raccoon with a tax problem.

Install Notes
- Use proper AR-15 armorer tools and verified assembly procedures.
- Small springs and detents should be installed carefully to prevent loss or damage.
- Function test all installed parts before live fire.
- Critical fire-control, bolt, extractor, ejector, and gas-system parts should be inspected by someone who knows what they are doing. YouTube confidence is not a torque spec.
Verify Before You Buy
- Verify this kit matches your AR-15 platform needs.
- Verify proprietary receivers, bolts, charging handles, or control parts before assuming compatibility.
- Verify whether you need a full build kit, a lower parts kit, or a shop repair assortment. This is a parts assortment, not a complete rifle kit.
- Confirm all installed parts pass proper safety and function checks before live fire.
