Am excluding the GUU series, while largely made of Colt parts they are not a factory item. Will add the MK18 MOD 0 later on.
除了GUU系列外，有很大部分的Colt的零件都不是原厂的零件，稍候会增加MK18 MOD 0系列。

Parts guide:
配件说明

Keep in mind that Colt used up quite a supply of 600 series parts on early 700 series Carbines. For example, just because a 723 should have a delta handguard ring don't mean that it will, because quite a few were sent out from the factory with the older slip ring.
值得注意的是，Colt有一部分早期的700系列的卡宾，使用的是600系列上的配件，比如说，因为有一小部分的723型出厂时候就是使用的旧款的固定环（太阳环），所以有些723型虽然使用了三角护木，但它的型号还是不变的。

Early 727 barrels, as in 1988 had a star stamped near the chamber, meaning unkown:
早期的727外管上，在1988年时，会有一个星型的刻印在枪膛的附近，但不知道代表什么

早于1989年在星型刻印之后，会有个O型刻印在枪膛附近（有些看上去象是C's）以表示这支枪的弹膛或枪膛是镀铬的



Starting in 95 a date code is stamped by the front sight base all though barrels can be found with dates as early as 02/95 production continued well into 1995 with some barrels being dated and other not. First two digits is the month, second two digit number is the year, this one 03/02:

The M4/A1 front sight base is similar to earlier front sight bases, except that the platform the sight post screws into is higher, these are marked with an F on the left side, and use a standard A2 front sight post. The "F" front sight base went into production in 1995. At least one large 1995 batch of flat top M4A1 Carbines were issued that did not have F front sight bases and used standard A2 front sight post.
M4/A1的前准星座和早期的很相似，区别在于准星的螺丝孔比早期的略高一些

最大的争议就是727的上机匣 枪管到底是A2外观还是M4外观

megatron

RO727应该是没有颈缩的管子。
