BUSHMASTER - The Best. By A Long Shot!
Here's Why:
Barrels: We machine our Barrels from either the best grade Chrome-Moly Vanadium Steel, or 416 Match Grade Stainless Steel. Our heavy profile Barrels (standard on most models) step down from 1" diam. at barrel nut to .750" at the sight base to improve heat dissipation and decrease barrel whip. The majority of our barrels are button rifled - right hand twist - 1 turn in 9", as we've found that the 1 in 9" twist gives optimum accuracy results with a broad range of ammunition, and will stabilize bullets up to 75 grains. DCM Competition Rifles are 1 in 8" twist for the very heavy bullets used in high power competition.
Chrome Lined Bore & Chamber: A chromed bore and chamber - as in most of our Chrome Moly Steel Barrels - can double the barrel's life if proper care and regular maintenance procedures are observed. The chrome protects against corrosion, and as it is harder than the barrel steel, it reduces friction, increases velocity, and aids in chambering and ejection. Chrome lined barrels also clean up easier because lead, copper and powder fouling simply does not adhere as easily to the chrome lining - so you'll spend less time cleaning after a day at the range. Note: With any chrome lined barrel, you should avoid leaving ammonia based solvents, bore cleaners, or pastes in long term contact with the chrome lining (i.e. over-night soakings) as the ammonia can react with the chrome to cause oxidation. Regular session cleaning will ensure proper barrel care and long life. We apply a Manganese Phosphate finish to our barrels, and other critical steel parts, to protect against corrosion and rust and to produce a matte black, non-reflective surface color. We do not paint any of our parts. Finally, Bushmaster rifles and carbines are laser boresighted at the factory to assure that the accuracy inherent in our barrels works in coordination with the sights that we put on them.
Manganese Phosphate Finish: We utilize the mil. spec. recommended protective finish for steel in our manufacturing. This finish protects against corrosion and rust, and produces the correct matte grey/black military surface color. We do not paint any of our parts.
Forged Front Sights: The front sight base is not a casting. Bushmaster uses only steel forgings which are far superior in tensile strength. Your weapon won't be disabled if you bang it against something!
Receiver Features: We machine our receivers to fit together with two standard mil. spec. push pins. This offers simple “tool-less” take down in the field - no need for two screwdrivers as with some other brands. We incorporate a brass deflector into the aluminum upper receiver forgings for ejected shell control and a raised “fence” area around the magazine catch button prevents accidental release of the magazine - all per latest military design specifications.
Rear Sights: We use the standard mil. spec. A2 Dual Aperture Rear Sight which incorporates adjusting knobs for both windage and elevation. Our A2 sights feature 1/2" incremental windage adjustment at 100 yards instead of the older version which offered only 1" increments - additionally, the adjustment knobs on the A2 rear sight eliminate the need for a sight tool. The beauty of the dual aperture flip-up is that the same sight can offer both quick target acquisition (with the field aperture) and fine distance sight picture (with the target aperture).
Stock and Grip: We install the latest A2 standard trapdoor buttstock - which is 5/8" longer than the original A1 - for a mil. spec. trigger pull length of 13.5 inches. The black thermoplastic pistol grip has finger groove and serrated back for solid grasp.
