I have wanted an AR type rifle for quite some time now.  I know many people own them and are very satisfied with them.

I was able to scrape together enough dough to finally buy one. So I purchased a Bushmaster XM15 rifle(basically an M4 carbine).

After finger-f@#$ing it for about a week, I got some free time to go to the range today and I wasted no time getting down there to test out my new toy.

Needless to say, my excitement was snuffed quickly after the first shot was fired.

This rifle, brand new out of the box, would not extract the rounds properly.

Almost every other shot, it would jam.  

The few spent shells that would eject, would limp out of the port with no force at all.  But most would just get stuck, sticking out sideways when the bolt came back home.

On just about every shot, the spent case was caught by the bolt one way or another.  

Sometimes the bolt would blow back and then forth, chambering the spent shell back into the breech...  

I tried switching ammo to see if this solved the problem, but to no avail...

Is this a common problem with these rifles?  I've read good things about Bushmaster. What do you think the problem could be???

Maybe I got a lemon with a faulty extractor?

Is there something I'm missing maybe???

First strip it and clean it and then properly lube it..shouldnt fire it right from the box with out doing this.Next to break in the moving parts use a full power xm193 or equal.Sounds like every thing is still quite stiff and it should be properly lubed and cleaned before breaking loose with it.

Sounds like the ejector is not throwing them far enough...use a few drops of oil on the ejector and with an empty case work it back and forth on the bolt face..oil the extractor.Im just assuming but did you lube it and clean it before using?


what kind of ammo are you using? and you did get a brand new mag with the rifle?And if you did clean and lube how did you oil it and what lubricant was used?Didnt fore it dry?

ChromeLined,

I must admit, I did fire the rifle out-of -box. hock.gif

I'm going to strip it down and clean/lube the rifle today...  Hope this works.

Someone on another site mentioned there could possibly be a gas leak and for me to tighten the gas key on top of the rifle.  I'm going to try that also.

Thanks for your input buddy...

Gas loss is a possible factor..you can tell after you clean it check the carrier key for any rattle.ARs are tight tolerance precision weapons..lube the bolt lugs,extractor ,ejector the carrier and carrier rails,recoil spring all moving parts.I would use and do use CLP...let it sit overnight so it has a chnace to work in.It will look a little dry the next day but CLP leaves behind a film...it will be fine and lubed enough when you fire it.Let me know how it goes.

You should have asked this question BEFORE you took your new baby out shooting:
"Just bought a new Bushmaster, what should I do before I go shooting her for the first time?"  

I would have told you to field strip it, spray it down and flush it out with Gunscrubber, clean it and lube it up with CLP.
Lube it to the point where you have lube dripping out of the bolt/carrier assembley and where you have lube weeping from the hammer/trigger pin holes.
Then lube it some more.  

The fire it for a few hundred rounds and tell us how it was.  

Bushmasters are notorious for FTF/FTE's when run dry, especially when new.

PLEASE don't go mucking with the carrier key.  The problem is almost certainly the rifle being dry.  The screws in the carrier key are staked, and all you will accomplish by mucking with them is loosening them so that they can work out later.

Read the manual.  Follow the cleaning and lubrication instructions.

Enjoy your new rifle.  Properly cared for, it should be just fine.

Wow, I cannot imagine pushing a bullet down a new bore with 50,000 psi behind it without running a few patches down it first.

Lets cut the newbie a little slack we were all new to shooting ARs at one time....you live and you learn man although not just with an AR but every firearm should be cleaned and lubed before firing some weapons like an AK or M14 type might be more forgiving if shot out of the box unless packed in that cosmoline crap.Your excitement got the better of you now you know..have fun and shoot safe

Yeah.  Don't think we're trying to break your balls, we're just trying to help.

Clean it, Lube it, Shoot it, Love it.

A little lube and it should run like a sewing machine.

yeah the same happened to me on my first time with my bushy, aftarwards I stripped her down and scrubed her and lubed it, and 2 weeks later went back out this time with 200 rounds and no issues with FTE or double feeding, she worked like a charm.

Same here with first range trip. Cleaned the bore and read the BM manual, but I had several jams in the first 100 rounds or so. After break in it has been flawless, give it some time.
