    .45 colt hunting carbine

    Ever consider an AR15 conversion in 45 ACP....deadly with 45 super ammo.....or a .460 Rowland......? Much faster reloads than a lever gun.....and due to the recoil energy being absorbed by the unlocking and cycling of the bolt.....faster follow up shots. Dedicated lowers are also available for...

    16" Midlength AR Problems

    Here is another simple thing to check that doesn't seem to have been mentioned.......strip the bolt out of the carrier and drop the carrier in the upper ....then turn the upper so the carrier can fall out....if it doesn't .....you have a gas tube dragging in the key and it can cause the problems...

    Pistol Caliber Carbine Dilemma

    I'm running the AR45 upper on a standard lower with a magwell adaptor that slips in like a mag and is held in by the stock AR mag catch. The USC mag is a Promag (around $38) and pretty well made...it has steel feed lips....shown in the pic is a 15 round mag.....the adaptors uses a paddle release...

    Need A Source For Unfinished Charging Handles

    For prototype I'd suggest just machining out of billet......actually simplier than making a fixture to hold the forgings.

    did I hear what I thought I heard?

    To those who comment on the waste of ammo from a full auto rifle.....in combat it has a purpose...it is called supressive fire.......basic squad tactics....one fire team provides supressive fire on the enemy position while the other team maneuvers....then the roles are reversed and the manuver...

    AR-15 bolt carrier assembly

    It is highly unlikely that a crack would propogate in a perfect circle......if it is in fact cracked....call Ruger.....they'll be VERY interested and eager to solve your problem. I would say slap a new bolt in....but I'm not extremely famaliar with an SR556 and unsure if a milspec bolt will fit...

    If you were going to build a defense AR-15, with the best of everything, what parts?

    For a defensive AR......I'd go with a DI .45 ACP. no chance of out of battery discharge like the blowback guns, recoil is non existent, they run cleaner than the blowbacks and even if your foe has body armor...hammer center of mass with 4 or 5 230 grain FMJ's and you will definitely make him/her...
