Restore reliable extraction and keep your rifle running with the LBE Unlimited AR-15 Extractor Kit (AREXTKT). This complete, drop-in parts bundle refreshes the critical extraction system inside your AR-15 bolt carrier group, helping solve stubborn issues like stovepipes, short-extraction, and erratic ejection. Built to OEM-level standards and finished in black, the kit includes a replacement extractor, extractor spring, O-ring/“donut”, buffer insert, and roll pin—everything you need to bring worn or weak parts back to spec.
Why This Kit?
Extractor wear is one of the most common causes of AR-15 reliability problems—especially on high round-count rifles, shorter gas systems, and suppressed builds. The LBE Unlimited Extractor Kit is a convenient, cost-effective way to rejuvenate bolt life, stabilize ejection patterns, and improve overall cycling confidence without buying a whole new bolt.
Key Features & Advantages
Complete Extractor Refresh: Includes extractor, spring, O-ring, buffer insert, and roll pin—replace all wear items together for best results.
AR-15 Compatibility: Designed for standard AR-15/M16 pattern bolts (5.56/.223 and many 300 BLK bolts that use the same extractor format; always verify your specific bolt style).
Enhanced Tension Options: The spring + O-ring combo increases extractor tension to help grab cases consistently—useful for suppressed rifles, short barrels, and dirty conditions.
Durable Construction: Quality materials and precise dimensions support long service life and repeatable lock-up on the case rim.
Smart Preventive Maintenance: A quick extractor refresh can restore reliability and is an affordable part of periodic BCG PM.
Roll Pin Included: Replace a fatigued or bent extractor pin during service; no need to reuse questionable hardware.
Performance You Can Feel
Cleaner Extraction: Strong, consistent case rim purchase reduces stuck cases and short-strokes.
Predictable Ejection: More stable ejection patterns aid brass management and help diagnose other cycling variables.
Confidence Under Stress: Whether you run classes, duty shifts, or hunt with your AR, proper extraction is the backbone of reliable function.

Compatibility & Fitment Notes
Platform: AR-15/M16 pattern bolt carrier groups.
Calibers: Typically 5.56/.223 and many .300 AAC Blackout bolts that share the standard 5.56 extractor design. Not for 7.62x39, 6.5 Grendel, 6.8 SPC, .308/AR-10, or other non-5.56-style bolts unless specifically stated by the manufacturer.
Bolt Style: Verify your bolt face and extractor style prior to installation.
If you’re unsure about compatibility, consult a qualified armorer or your bolt manufacturer’s specifications.
Ideal Use Cases
High-Round-Count Carbines: Replace tired extractor components to maintain reliability.
Suppressed Rifles: Added extractor tension helps counter increased fouling/pressure.
Short Gas Systems (Carbine/Pistol-Length): Improve case control in faster-cycling setups.
Preventive Maintenance Kits: Keep one in your range bag or armorer’s kit as a go-to spare.
Maintenance & Installation Overview
Safety First: Verify the firearm is unloaded; remove the BCG from the upper and the bolt from the carrier.
Inspection: Check the old extractor for chipping, rounding, or loss of tension.
Replacement: Swap in the new extractor, spring, O-ring, buffer insert, and roll pin per standard AR-15 BCG service procedures.
Function Check: After reassembly, confirm free bolt movement, extractor tension on a dummy round, and proper ejection at the range.
This is a small-parts service job. If you’re not experienced with AR-15 BCG maintenance, have a qualified gunsmith/armorer perform the work.
