Conversion Knight’s Armament SR-15 CQB MOD 2 M-LOK – 11.5”:

Knight’s Armament is a prestigious manufacturer of AR15 family rifles and shotguns.
Eugene Stoner himself (the creator of the AR10 and by extension the AR15/M16/M4 family) joined Knight’s Armament during the last years of his career to finalize his creation in the form of the SR15, SR16 and SR25 ( became the M110 adopted by the US Army). The initials ”SR” stand for ”Stoner Rifle”.

The SR-15 is the civilian version of the SR-16. It has many improvements intended to carry this platform into the 21st century.
Its very particular floating handguard gives the upper assembly the rigidity of a monolithic system.

Main features:
– Semi-automatic direct throttle conversion for AR-15 (compatible with AR-15 dimensionally MilSpec).
– Fitted with the new MOD 2 gas borrow collar fixed not by pins, but by a lock nut that can be removed from the front of the barrel.
– Longer gas system to soften the recoil of the weapon and therefore the recovery.
– 11.5” cold hammered barrel chambered in 5.56 NATO, CMV steel phosphated externally and chromed internally (1:7” pitch) – The
barrels are forged in the USA by Knight’s Armament from a special French steel having strength and longevity exceeding the MilSpec standard.
– The rifling pitch of 1 turn in 7” makes it possible to stabilize the MK262 or any other cartridge equipped with a 77-grain projectile as well as all other conventional cartridges with a lighter projectile.
– Cylinder head box in 7075T6 aeronautical alloy machined from a forged part.
– KAC flash hider on standard 1/2″x28Tpi thread.
– “E3” cylinder head whose locking lugs are radiused to eliminate any incipient breakage (this cylinder head has a life expectancy 4 times greater than an M16 cylinder head or M4).Although this cylinder head is specific, an SR15 nevertheless accepts a standard cylinder head in case of force majeure.-
The cylinder head has an improved extractor equipped with 2 springs for optimum reliability.
– This conversion is compatible with all AR15 receivers whose dimensions are MilSpec.
– Barrel extension and breech box feature M4 type feed ramps.
– The cocking lever has an oversized bolt.
– The closing assistance button is retained.
– The new URX 4 floating picatinny handguard is octagonal with a Picatinny top rail and 7 faces machined to M-LOK standard to attach accessories.
– The handguard is very long (10.75”) and allows all grips, including outstretched arm at the end of the handguard, moreover its section is small and provides an exceptional grip.
– The handguard is one piece and constitutes the barrel nut, giving the assembly the rigidity of a monolithic system.
– Type III MilSpec anodizing on receiver, receiver, and handguard.
– 2 quick ball sling attachment points (1 on each side of the handguard)
– Caliber: 5.56×45 (223 Rem.)
– Weight: 1.7 kg
– Length: 52cm
– Length of a weapon equipped with this conversion: approximately 73cm (stock retracted, if a Magpul CTR or MOE stock is used).
– Delivered with:
    – a folding handlebar in aluminum and stainless steel Knight’s Armament adjustable in height without tools.
    – a folding eyepiece in stainless steel Knight’s Armament adjustable in the 2 axes and calibrated up to 600m.
– Made in USA (for all component parts)

– Conversion classified in category B5 (out of quota).

NOTE concerning the M-LOK system:
The M-LOK standard was developed by MAGPUL to quickly attach an accessory to a handguard with the following advantages:
– obtaining a smaller diameter handguard to improve grip.
– be able to fix the accessory from the outside without a part to be positioned inside the handguard
– be able to create a handguard in synthetic material which would not be weakened by this system (although most are made of aluminium)
– have a positioning accuracy after disassembly/reassembly at least as good as the Picatinny/NAR standard.
– This standard is free of rights and any manufacturer can integrate it into its production without paying royalties to MAGPUL.
