AR-15 Rifle & Manufacturer Comparison
Many questions are asked about the AR-15s of the different manufactures. Here are listed all the major Manufacturers (not custom houses or gunsmiths) that produce
them. All the important details are listed and can be compared. AR-15 intended for defensive duty or field use should have M16 chambers (for reliable extraction
especially when dirty) and have at a minimum chrome lined chambers (again for reliable extraction). Chrome lined bores are highly desirable for AR-15s that are
used outside for their resistance to corrosion and ease of cleaning, and long life. Stainless barrels are considered the most accurate. SAAMI spec chambers for .223
contribute to high accuracy, but may cause problems if using mil-spec M193/M855 (see the ammo warning at the SAAMI website, search on "223") and length of
cartridge (Mil-Spec does allow for a longer neck). Also, if the chamber gets dirty or there is dirt on the ammo a SAAMI chamber will more likely have problems. The
4140 chrome/moly steel barrels are the most economical while providing some resistance to rust (note these are not chrome lined – there is just some chrome in the
steel to help with corrosion resistance). As a rule Stainless are the most accurate, followed by a good chrome/moly (like Colt's), then chrome lined. However, a good
chrome lined barrel (like Bushmaster's) can outshoot a mediocre chrome moly barrel (cheaper AR brands). Good chrome lined barrels can do better than 1MOA with
decent ammunition (just like great stainless barrels can do very poorly with cheap ammo). HBARs (heavy barrels) are now standard for AR-15s, but if you intend on
carrying your rifle in the field I'd recommend something lighter. A variety of methods can be used to lighten the barrel; the A1 style is the lightest, the A2(20")/M4
(16" or 14.5") have a thin barrel under the hand guards and a HBAR in front of the sight, fluting reduces weight the least, but keeps a stiffer barrel than the other
methods. Standard Trigger Pins are the most desired since they allow you to get replacement fire control parts easily (and inexpensively), also you can use demilled
(full auto notches removed) M-16 parts if AR parts get hard to find. Standard pins also include the front take down pin (pivot pin); the military style push pin (same as
the rear one) is the most common and easiest to use. A DCM variant is an AR-15 setup for DCM/CMP Service Rifle matches (all the match goodies while conforming
to the rules).
