Combinations of barrels and buttstocks As long as you keep the short (collapsible stock style) buffer spring with the short buffer in the short lower receiver extension and the long (rifle style) buffer spring with the long buffer in the long lower receiver extension it doesn't matter what barrel length you use. Free float handguards Install your own Free Float Tube - step by step instructions Collapsible stock spring length range: 10 1/16"-11 1/4" Rifle stock spring length range: 11 3/4"-13 1/2" Do not stretch the buffer spring, or any spring, to increase the length. Do not clip coils off to gain function.

Double check your assembly then dry cycle the lower by hand to check for mistiming. The tip of the disconnector should almost touch the middle hammer hook when you cock the hammer by hand. Keep something soft, like your thumb, between the hammer and lower in case the hammer slips. Do not allow the hammer to strike the lower. With the hammer cocked onto the disco, SLOWLY release the trigger. The hammer should jump up slightly and now be resting on the tip of the trigger. Repeat this several times. The hammer should not fall. 20AUG03 9JUL03 10AUG03 21JUL03 Double tap type experience at the range? pin diameters? 26JAN04 3MAY04 .223 vs. 5.56 Reamer Dimensions ArmaLite's take .223 vs. 5.56 NATO Ammo-Oracle Articles 5.56 .233 differences Chamber differences Keyholing Usually caused by the wrong twist for the length of the bullet. Can also be caused by the bullet striking a muzzle device. With extremely short barrels (<9”) keyholing can caused by the lowered muzzle velocity combined with a slightly slow twist. 13OCT03 |
