Charles Daly D-M4LE Carbine Guide and Review

[Stickman]

In the world of receiver extensions, there are two types, one is the mil spec, and the other is a commercial variant. Often called "buffer tubes", the actual terminology is receiver extension (RE). The military sized RE is machined out of one piece of aluminum, and has deeper engagement with its threading into the lower receiver. The commercial RE is extruded, and has threads which are more shallow. While there aren't many cases of commercial RE failing, there are plenty of cases of owners finding a variety of different dimensions. The mil spec REs are well built, and tend to provide a wobble free stock. Its another small detail, but its one that many people, including myself find important.

The Charles Daly D-M4LE also comes with the "H" buffer. Buffers are available in several different weights, with the "H" being slightly heavier than its non-H sibling. The "H" reduces bolt bounce, smooths out the gas curve and alters the muzzle rise for those shooters which are in tune with their weapon. While it might not be mandatory to make the weapon run, its another item which I would upgrade if my weapon were without it.
