KAC E3.2 Bolt Assembly
$379.50The SR-15 E3.2 Enhanced Bolt features a number of components designed to exceed expectations for durability and service life, even when exposed to extreme and unrelenting conditions. Dual ejectors considerably mitigate wear and prolong lifespan compared to the legacy single ejector, delivering sustained ejection force to the case head due to strategic ejector placement. A vibration-dampening o-ring works synergistically with the extractor, ensuring a constant and positive force of the extractor claw against the case rim throughout the extraction and ejection processes. Stress relief features incorporated into the lugs significantly extend the service life. Its radiused lugs and reduced diameter cam pin hole render it the most durable AR-pattern bolt known to date. The dual-spring extractor, featuring improved leverage, adeptly resolves extractor durability and operational issues commonly encountered with short-barreled carbines. It is a proprietary bolt designed specifically for use in SR-15 and SR-16 rifles.
E3.2 Enhanced Bolt Features
Dual Ejectors – Provides more positive ejection for increased reliability with suppressors.
Enlarged Bolt Face – Provides more positive engagement in the chamber and ensures proper seating upon cycling.
Rounded Bolt Lugs – Less prone to chipping or cracking than traditional square lug designs.
Reduced-Size Cam Pin – Allows for a thicker bolt web, strengthening a common failure point in the AR-15 bolt design.
Enhanced Reliability Extractor – Shaped like a “T” this extractor’s pivot point is shifted forward to apply constant pressure on the case rim and reduce extraction failures. Its dual extractor springs provide a fail safe in the event that one fails during hard usage.The E3.2 bolt is only compatible with SR-15s and KAC E3 barrel extensions.

KAC URX 4 IBN Keymod Rail 5.56mm 14.5″ Length
URX 4 The URX 4 is a continuous top-rail system that utilizes the Keymod mounting brackets developed by Vltor and Noveske. This rail system is built stronger and more stable than previous designs due to the absence of a removable bottom rail. The modular layout allows an end user to fully customize exactly where to place accessories without the use of specialized tools, small parts, or additional forces applied to the barrel. The URX 4 is currently available for 5.56 rifles in 8.5″, 10″, 10.75″, 13″, and 14.5″ lengths, and is equipped with Knight’s unique IBN mounting configuration. The idea was to create a more modular, and thus more serviceable, rail system that still maintains its strength and stiffness. Th IBN system torques the rail onto the weapon and allows the rail to act as the barrel nut.
This design was developed to increase stabilization and provide a simpler solution that requires less specialized tools to install and maintain. A full array of modular accessories, iron sights, and panel kits utilizing the Keymod mounting brackets have been developed specifically to accompany this rail system. With the introduction of the URX 4, Knight’s Armament Company demonstrates its continuing determination to intelligently design effective products. It is not suggested to use this rail with a 14.5″ or shorter barrel unless using a muzzle device such as the AAC flash hider which can be installed from the end with a tool.

M4 Carbine RAS, 5.56mm, with three 11-rib panels The KAC M4 RAS (Rail Adapter System) was developed for use on the US military’s M4 Carbine, and with over 1 million rails issued to date, it is one of the most battle proven designs available for the AR-15 platform.

What sets the M4 RAS apart from other 2-piece quad rails on the market is that it securely locks to the rifle’s barrel nut via a clamp and screw arrangement, making it a very solid foundation upon which to mount tactical accessories. Includes three KAC 11 Rib Rail Panels. For other rib panel lengths and colors, click here Rifle Requirements: The M4 RAS is a drop-in replacement part for standard, 2-piece polymer, M4-type handguards. The rifle must have a carbine length gas system, delta ring assembly, fixed front sight/gas block, and round handguard end cap. Lighter barrel profiles work best (M4 or Government contours). Heavier barrel contours may require modification to the inside of the rail. For AR-15/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions are included. Specifications: Weight: 8.9oz Length: 6.25? Free Float: No Material: Aluminum Finish: Black Anodizing
