The Model 605B had no forward assist, but had a four-position selector switch which has a 360 degrees motion that could move clockwise or counterclockwise. The Model 605A CAR-15 Carbine was a shortened version that can be brought aboard in vehicles or helicopters. The CAR-15 Heavy Assault Rifle M2 is similar to the M1 but instead of a 30-round magazine, the M2 is a belt-fed. The CAR-15 M1 was designed to feed from a 30-round box magazines. The CAR-15 Heavy Assault Rifle M1 was a heavy-barreled version of the standard CAR-15 with a bipod attachment which is intended to be use as a Squad Automatic Weapon (SAW). The Model 603 CAR-15 Rifle was adopted by the United States Army as the XM16E1 and then later as M16A1, and the Model 604 CAR-15 Rifle was adopted by the United States Air Force as M16. The CAR-15 was a family of M16 rifle based firearms. For example, the 9Г—19mm is pronounce as 9 by 19 millimeter.ДЎ973 Colt AR-15 SP1 with slab side lower receiver The вЂњГ—вЂќ in cartridge names are pronounce as by. For example, 9Г—19mm refers to a bore diameter being 9mm and has an overall case length of 19mm. The second number reflects the case length in inches or millimeters but again, usually measured in millimeters. The first number reflects the bore diameter in inches or millimeters but usually measured in millimeters. The two numbers used in cartridge names are the length for modern cartridges. This list can also be use to find firearms base on the AR platform for your OC to use (though most of them are not that unique by external design but most are unique in mechanical design and/or cartridges use). If you have ever wanted to hunt with your old SP1 or clone and iron sights wonвЂ™t cut it for you these are just the thing for getting some real use out of the old retro AR15.This is here for assisting with distinguishing AR-15/M16 platform from very known based firearms such as the M4, M16, and the HK416 along with additional information (I will improve this list over time). Especially on an older SP1 rifle or M16 clone. The little scopes are a neat little piece of AR15 history and they are a lot of fun to shoot with.

Inside was simple instructions on how to zero and use and take care of the optic. The copes came in a cardboard box with leather end caps to protect the glass. They can be used for some pretty decent precise shooting in reasonable conditions. 3x and 4x are still usable and hunters and snipers of years and wars past used scopes not even as powerful as 3x for serious work. Now they are too collectible and slightly rare to be out using for much more than fun anyways. I think the days of this being your only choice for an optic for your AR/M16 may be over. It is something a cheek rest could remedy, but why bother. Like all carryhandle mounted scopes, there is the usual issue with cheek weld. Other than the older models having a slightly shinier finish than the newer made ones, the y are nearly identical. They did see actual combat use from Vietnam to the first Gulf War.Д®xcept for a few very early makes, the Colt optic is usually marked Made In Japan. They are not ACOGs, so they can not take that kind of abuse. Of course you can find some that have been used and abused and see some narfed up glass. I have never been much of a post fan myself. The crosshairs for the scopes came as a post of a duplex crosshair. Even later models can safely assumed to be matched for the M193 type load. At the time there wasnвЂ™t much else out there. The optic is calibrated for the M193 military load which is the 55 grain bullet. The BDC does match and work pretty well and it is repeatable on all of the examples I have tried over the years. Once the optic is zeroed at 100 yards, the BDC can be used for fast and easy range adjustments. The rear of the optic is adjustable for parallax. ll adjustment values are 1/4 inch per click. Windage adjustment is on the right side of the scope body and can be adjusted after removing its cover. To do this you remove the top cover to gain access to the finer adjustment screw. The optics have a BDC turret that can be used after finer zeroing at 100 is done. Once the optic is installed, the iron sights on the rifle or carbine can still be used. A threaded post protrudes out the bottom and a lever is used to tighten the assembly to the underside securing it tightly into the carry handle slot. The optic attaches to the carry handle of the upper by using the hole in the center. It is one of the first optics to ever be designed specifically for the AR15/M16 and was used during the Vietnam war. Almost as long as the AR15 it was meant for. The colt 3Г—20 and 4x 20 scopes have been around a long time.
