RE: grizzly caliber
HMM my Bad I havea differentversion I guess we will have a little school here. For the proper answer to the young mans question to clear up any questions he may have.
History
The AR-15 is based on the 7.62mm AR-10 by Eugene Stoner of the Fairchild ArmaLite corporation. The AR-15 was developed as a lighter, 5.56mm caliber version of the AR-10. (The "AR" in AR-15 comes from the Armalite name and does not stand for 'assault rifle' as is commonly believed.)
ArmaLite sold its rights to the AR-10 and AR-15 to Colt in 1959. Colt marketed the AR-15 rifle to various military services around the world, including the U.S. Air Force, Army, and Marine Corps. The AR-15 was eventually adopted by the United States military under the designation M16. However, Colt continued to use the AR-15 trademark for its semi-automatic variants (AR-15, AR-15A2) marketed to civilian and law-enforcement customers. The original AR-15 was a very lightweight weapon, coming in at less than 6 pounds with empty magazine, though later heavy-barrel versions of the civilian AR-15 can weigh upwards of 8.5 lbs.
Today the civilian-model AR-15 and its variations are manufactured by many companies and have captured the affection of sport shooters and police forces around the world due to their low cost, accuracy, and modularity. (Please refer to the M16 for a more complete history of the development and evolution of the AR-15 and derivatives.)
Some revolutionary or otherwise notable features of the AR-15:
[*]Aircraft grade aluminum receiver[*]Modular design allows for a variety of accessories, renders repair easier[*]Small caliber, high velocity round[*]Synthetic stock and grips do not warp or splinter[*]Front ironsight adjustable for elevation[*]Rear ironsight adjustable for windage and range[*]Wide array of optical devices available in addition to or as replacements of ironsights[*]A direct impingement gas system [/ul]
Semi-automatic and automatic variants of the AR-15 are effectively identical in appearance. Automatic variants have a rotating selective fire switch, allowing the operator to select between three modes: safe, semi-automatic, and either automatic or three round burst depending on model. In semi-automatic only variants, the selector only rotates between safe and semi-automatic.
[edit] Technical data

Newer configurations use 1:9 and 1:7 twist rates. There is much controversy and speculation as to how differing twist rates affect ballistics and terminal performance with varying loads, but heavier projectiles tend to perform better with faster rifling rates.[*]Magazine capacity: 5, 10, 20, 30, 40, 90, 100 (see below) [/ul]
Standard issue magazines are 20 or 30 round double column magazines; drum magazines in 90 and 100 round capacities also exist, such as Beta C-Mags. Low-capacity magazines are available to comply with some areas' legal restrictions, hunting and because larger magazines can inhibit shooting from a benchrest.
Aftermarket upper receivers that incorporate barrels of different weights and lengths, and handle different caliber ammunition, abound for this rifle. They are very easily installed, due to the rifle's modular design. Prices tend to be reasonable. These calibers include:
[*].22 Long Rifle[*]6.5 Grendel[*]6.8 SPC[*].45 Bushmaster[*].300 Whisper[*].458 SOCOM[*]9mm Parabellum[*]7.62x39mm[*].50 AE[*].50 Beowulf[*].50 BMG[*].45 ACP [/ul]

RE: grizzly caliber
This was not a simple question as this has many variables.
Nothing here was ment to make you look like a moron.
There was a question asked and simply answered it this timeso there was no confusion.
Again it was my bad for not giving a complete answer the first time.
