Best Answer

On the actual military weapons (whether they have the M4 profile barrel or the government profile barrel), the barrel length is 14.5 inches. On civilian "M-forgeries", a 16 inch barrel is more commonplace, although the 14.5 inch barrels can be found on the civil market, provided that they are equipped with a permanently mounted flash suppressor or muzzle brake of a sort which brings the overall barrel length to 16".

Is a m16 different than a m4 carbine?

Yes. Principle differences between the M16 and M4 include: M16 has a 20 inch barrel while the M4 has 14.5 inch barrel, M16 has a fixed buttstock while the M4 has a retractable six-position buttstock. Virtually all M4s have a 20 millimeter accessory rail, while only M16s after the A3 variant have the rail. The M4 carbine also has a stepdown in the barrel to accommodate the M203 grenade launcher due to its thicker barrel profile. Performance-wise, the M4 is also less accurate at range due to its shorter barrel, but is easier to maneuver in cramped environments.

Aside from the obvious differences, such as the collapsible buttstock and shorter barrel (14.5 inches vs. 20 inches), there are some more subtle ones. The M4 has a higher Front Sight Base to compensate for the shorter sight distance, the M4 uses a different buffer and buffer spring than the M16, the M4 has an indentation in the barrel to accommodate the M203 grenade launcher mount developed for the M4 (government law enforcement M4s typically have a barrel without this indentation), and the M4 has a longer set of feed ramps which also extend into the lower receiver itself.

What are the differences between the M4 and M16?

The M4 is basically a carbine version of the M16A2 rifle, and was developed both to reflect the development of the M16A2 over the previous M16A1, and to correct deficiencies which had been identified with the XM-177 (which was the carbine variant of the M16A1).General differences between the M4 and M16 include:M4 has a four position collapsible buttstock (vs. the fixed buttstock of the M16)The weight of the buffer is different in the M4 than the M16The M4 has shorter handguardsThe M4 has a shorter gas systemThe M4 has extended feed ramps cut into the upper receiver for ease of chambering rounds.The M4 has a 14.5 inch barrel, vs. the 20 inch barrel of the M16The M4 has an "F" marked front sight base, which is designed to compensate for the difference in sight radius between the M4 and M16The M4 has an indentation in the barrel profile to facilitate the mounting of an M203 grenade launcher.Some people often cite the removable carry handle of the M4 as one difference, but the first production run of M4 carbines had the same fixed carry handle as the M16A2 (I was actually issued one when I was in the FL National Guard).
