AR-15 fans can finally get their hands on a large quantity of 5.56x45 XM855 "Penetrator" ammo manufactured by Lake City via this 1000-round pack of Federal American Eagle ammo.

These 5.56x45 XM855 cartridges fire 62gr full metal jacket (FMJ) bullets with a steel penetrator inside with the famous green tip marking to easily identify the rounds. These bullets resist expansion and penetrate deeply. They are superior practice rounds for shooters who are looking to get serious about their training. These rounds carry a fast muzzle velocity of 3020 feet per second.

Lake City assembles these premium rounds using military-grade powders, primers, and new-production brass casings. The casings are non-corrosive and reloadable, and when stored properly they can sit on a shelf for an extended period of time.

For those of you who know and trust the quality of Lake City ammo, this is an unbelievable opportunity to stock up on 5.56x45mm XM855. Don't miss out! Order your 1000 round bulk case today!

A: Thanks for reaching out Don! This ammo is currently out of stock, but we'll update its price the instant we get more in our warehouse. I can't say exactly when that will be, but we do update our inventory frequently. I hope you'll check back in with us again soon!

A: Absolutely! You may experience the best accuracy with a 1:8 or 1:9 barrel twist, but this ammo is optimal for such an AR-15.

Posted On: 5/25/2020 By: Daniel

A: Hi Daniel! The M855 cartridge's bullet has an FMJ, steel tip, and boat tail as a rule!

A: Let us preface our answer with a disclaimer: We are not lawyers, and we will never become lawyers. (Any law school that would accept us couldn't possibly be a very good one, either.) That said, it is our understanding that the state of New Jersey bans "armor piercing" ammunition. HOWEVER, it is our understanding that M855 rounds don't meet the threshold for what constitutes "armor piercing" and are therefore legal to purchase and own in New Jersey.

A: We've never encountered a problem with loose-packed ammo. Brass can't scratch itself, and it's harder than the copper that jackets bullets. The rounds are also packed tightly enoguh in there that they only negligibly shift around during transport. Loose-packed rounds are great when you want to do a lot of shooting and don't want to peel apart a hundred little cardboard boxes!

A: Steel core can be banned at some indoor ranges, it's best to check with the range you're looking into.

A: Hi Flip! This ammunition would not be a great fit for hog hunting. Not only will you not get much expansion out of the bullet, but some states even have laws regarding not hunting with full metal jacket ammunition. If you need help choosing a hunting ammo, please don't hesitate to contact us at customerservice@bulkammo.com.

A: Yes. You pay our web-published price (plus shipping and tax, if any) and then submit the rebate request directly to the manufacturer for reimbursement by them.

A: That is part of the annealing process. If the ammo is spotty it could be residues from the chemical washes used to seal the ammo. It is not rust or corrosion.

A: You can always select "overbox my case" during checkout and your package will be "double boxed" with the outer case having no markings except the required DOT symbol.

A: Hi Bob, These are Federal Lake City Rounds. They are made in the US.

Posted On: 1/25/2017 By: Ian

A: Hello Ian, This specific Lake City ammunition is loose packed in 1000 pieces per case. It does not come loaded on stripper clips or in individual boxes.

A: Hello Terry, The G1 B.C. of an SS109 bullet is .304. The G7 B.C. of the SS109 bullet is .177

Posted On: 9/23/2015 By: Ryan

A: Hello Ryan, This 5.56 ammunition is all new manufacture from the Lake City manufacturing plant.

Posted On: 8/24/2015 By: Kevin Bigler

A: Hello Kevin! Lake City lists the velocity of this round at 3000 fps +/- 40 fps.

Posted On: 12/25/2013 By: Larry

A: Hello Larry, Yes, these 62gr. FMJ rounds in 5.56 by Lake City are new production and not reloaded. They are brass cased and boxer primed so you would be able to reload the cases once fired.

A: From a quality and performance comparison, you will not notice a difference between the two. While there is always talk of the XM's being duds and underperforming, we, and our customers have not discovered any issues with these rounds. The X designates the lot numbers that will be used for private/ civilian use versus military/ law enforcement use.

A: The steel core featured in this 5.56x45 NATO green tip round is not classified as an Armor Piercing (AP) round. The steel core will penetrate targets easier than similar rounds without a steel core. The rounds may be prohibited in some indoor ranges as these will not pass the magnet test.

Posted On: 3/11/2013 By: Andy

A: The green tips on these 5.56x45 rounds indicate the bullet features a steel core. There will be no tracer element included on the bullet. Rounds that have an orange ink painted in place of this green tip will indicate a tracer round.

Posted On: 1/29/2013 By: Andy

A: If your rifle ( Bushmaster, S & W etc.) has a marking of .223 Rem but does not include 5.56x45 NATO, the rifle has been designed to shoot .223 ammo only. The 5.56x45 is very similar, though its increased pressure may be unsafe for the .223 chamber and is simply not worth the risk shooing. If you rifle has both caliber markings, or just 5.56, both 5.56 and .223 ammo will work in your rifle.

Posted On: 12/21/2012 By: Mark L

A: Correct. This 5.56x45 NATO ammo will work well for your Colt. The rounds do contain steel which may not be allowed in some indoor ranges. This will not cause any harm to your rifle. The brass casings are excellent for reloading and do not contain any corrosive components.

Posted On: 3/19/2012 By: Dave

A: We do not do back orders, but we have other quantities of XM855 in stock at the moment. It would be best to buy while you can instead of waiting for the larger quantity.
