When we released the CTR-02 (Competition Tactical Rifle of 2002), it represented an industry milestone for AR-15 rifles and is still considered the benchmark of tactical competition rifles. Over the years, it has been the choice of the nations top shooters, including Daniel Horner and Robby Johnson of the Army Marksmanship Unit. The reliability and accuracy of the CTR-02 have become legendary. The CTR-02 Match Ready Rifle is optimized for peak performance in 3-Gun competition but also serves as a fantastic all-around rifle recreation or hunting.

Bill Wylde of Greenup, Illinois compared the two cartridges and changed the chamber of the rifle's barrel to a specification called the .223 Wylde chamber. The chamber is made with the external dimensions and leade angle found in the military 5.56×45mm NATO cartridge and the 0.2240 inch freebore diameter found in the civilian SAAMI .223 Remington cartridge.[4] Rifles with a .223 Wylde chamber will typically accept both .223 Remington and 5.56×45mm NATO ammunition.[4]

Note that while the .223 Remington and 5.56×45mm NATO chambers have slightly different dimension, the cartridges themselves are identical in exterior dimension.[4] The chamber dimension differences are often confused with the cartridge dimensions, and it is often erroneously thought that the cartridges have different dimensions. However, the cartridges are loaded to different pressure levels (55,000 psi vs 62,000 psi), with the 5.56 NATO being greater.[5] The .223 Wylde chamber allows the use of both pressure levels safely, while also increasing accuracy potential across the range of potential bullet selections.[3]

Wylde's hybrid chamber was designed to exploit the accuracy advantages of the .223 Remington chambering without problems concerning over pressure or compromising the functional reliability of semi-automatic firearms like the AR-15 family of modern sporting rifles when using 5.56×45mm NATO military ammunition.[6] Coincidentally, it can shoot the relatively long and heavy 80-grain (5.18 g) bullets commonly used in Sport Rifle Competitions very well, and is one of the preferred chambers for that task.[7] The .223 Wylde chamber is used by rifle manufacturers who sell "National Match" configuration AR-15 rifles, barrels and upper receivers.

The major dimensional difference between the chambers that fire the .223 Remington and the 5.56 x 45 NATO is the longer and larger-diameter "freebore" in the 5.56 chamber (0.0566" vs 0.0250" length, 0.2265 vs 0.2240 diameter). Freebore is a short and smooth section of the barrel that is located after the case mouth, but located before the start of the rifling "grooves and lands". The standard Wylde-spec chamber uses an even longer freebore length of 0.0619, to allow longer bullets (and thus heavier) to be assembled at the absolute maximum "Cartridge Over All Length" (COAL). Be aware that the freebore of a chamber can be special-ordered in a variety of lengths.

The larger diameter of the 5.56 freebore allows for continued functioning when experiencing minor fouling of gunpowder residue build-up, which is essential for the rapid firing of high volumes of ammunition in combat.

The .223 Remington cartridge is currently manufactured to be used as a single-shot in a bolt-action rifle, so the .223 chamber benefits from a slightly tighter dimension in several places, compared to the 5.56 NATO. The slightly "looser fit" in the military 5.56 chamber increases operational reliability during rapid cartridge insertion and extraction. This is of special interest when taking into consideration any minor manufacturing variances in the ammunition, and also minor case dents acquired during transportation during combat. This cycling reliability is of intense concern when using the 5.56 NATO cartridge in a light machine gun, such as the M249, as well as the general-purpose M4 combat rifle.

However, the larger-diameter 5.56 freebore can occasionally have a minor detrimental effect on accuracy on any given random shot, when using the standard combat 55gr M855 cartridge. The .223 Wylde-spec chamber uses the slightly looser 5.56 NATO chamber dimensions around the case for cycling reliability in a semi-auto firearm, along with the tighter freebore of the .223 Remington for a more consistent accuracy.

It has been commonly stated that a 5.56 chamber can fire a .223 cartridge without concern, but firing a 5.56 cartridge in a .223 chamber is ill-advised. To further clarify, a given .223 Remington-chambered rifle may be able to safely handle the elevated chamber pressures of a 5.56 NATO cartridge, but they are not required to be manufactured to do so. All ".223 Wylde" marked barrels are required to meet the higher pressure standard.
