Compare this 62 Grain Full Metal Jacket Boat Tail (FMJ-BT) ammunition from Federal to some other 5.56x45 Ammo (AR-15) |


This is the famous and hard to find mil-spec M855 steel core 5.56x45 ("green tip") penetrator ammo you have heard about!

It is loaded to NATO specs and is NOT intended for use in commercial or bolt-action rifles chambered for 223 Remington ammo - but is is perfect for your AR15! Please check with your gun manufacturer prior to purchasing this ammo (most AR15's are fine, but it is best to check first!).

Each round is brass-cased, boxer-primed, non-corrosive, and reloadable. It is both economical and precision manufactured in the United States by an established U.S. cartridge producer.

Rafael Gonzalez-Vizoso ( Wed, 06 Aug 2014 21:29:58 +0000 ) : At my firing range, they insist this is a armor piercing round. I have not found any info to corroborate this assertion. Could someone clarify this for me? Thanks. RGV
Heidi At Lucky Gunner ( Fri, 08 Aug 2014 13:39:05 +0000 ) : Hey Rafael, that's a really common question, thank you for asking! There is a lot of confusion about whether "penetrator" means armor piercing. This article from our friends over at ITS Tactical explains how the Federal M855 was removed from the ATF's armor piercing list and is a pretty good resource. That said, your range might have other ideas.http://www.itstactical.com/warcom/ammunition/military-ammunition-and-why-green-tip-m855-is-not-armor-piercing/

Q: I just purchased my 1st AR rifle (del-ton Rftm M4) What would be the best defense ammo I can buy for this type of gun in the 5.56? Thank you for your help, and continue doing a great job :)

Posted On: 6/1/13 By: Edgar Ramos

A: You may find that most handgun ammo usually offers a full metal jack round for target practice and a hollow point round for defense. Considering the 5.56 round, a FMJ round has been found to be a good round for both target and defensive applications. The most popular rounds for this caliber will be found in either a 55 grain or 62 grain bullet. Both will perform well in most AR-15 style rifles. If you plan to use your rifle at an indoor range, an XM193 bullet will be desired as this will not stick to a magnet. Some will consider a .223 soft point of hollow point round for defensive applications as this round will safely fire in a 5.56 rifle. If you have any additional questions about this caliber, please feel free to send us an e mail or call!
