Praxis: The $5 Part that Saved My AR-15

What I found is an extractor spring that can stand up to the pressure of the Steel ammo especially Tulammo. The part is called the BCM Extractor Spring Upgrade Kit and it is only $4.95 plus $7 shipping though(they also have a 3 pack for $11.95 so that is the better deal). All it consists of is a small spring, small O-ring and a tiny rubber extractor insert. One of the great things about AR-15s is that they are so easy to take apart. I was able to get this fix done quite quickly. Below is a video of the easy install and the differences in the spring (I already had it in so I will just show you how to get to it). Just putting this little piece inside my gun has made it work a million times better. It extracts correctly and I don’t have casings getting stuck as I did before. Though I would still recommend getting better ammunition especially like brass Remington at least I now have the option to use some of the cheaper ammunition for target shooting. If there is no other upgrade you get for your AR15 get the Extractor spring upgrade as it is the best bang for your buck and may help you be able to shoot cheaper ammo with less to no malfunctions.

Agree 100%. When I first got into ARs about five years ago, a slick salesman talked me into getting a DPMS. After several frustrating range trips where my new gun choked on several different types of brass ammo, I stumbled upon this fix. Since installing it, I have had zero FTEs and zero double feeds in over three thousand rounds.

Not ALL should be modified, check with you manufacturer.
I own a RRA Elite Operator and 100% in warranty.

My experience has been that a lot of Tulammo will degrade the barrel rifling, especially at the point of the gas check. Also, it takes up to 10,000 rds to degrade the barrel in this way. I agree about the DPMS, good price, problems with it though. Rebuild kits from them have disconnects with splits in them, through the thickness of them, but a complaint and they replaced it for free. Carefully examine any lower build kits from them. SOP for me and mine is to carry a new firing pin, firing pin retaining pin, extractor, extractor spring and extractor bushing, and extractor pin, wrapped, taped, in the butt stock of the rifle. Cost is very small, adds little weight, and can be a real help in times of uh-oh.

Steel jacketed ammo (tula, wolf, ruag, silver/brown bear, MSI) eats up your rifling at the throat at about twice the rate that a copper jacketed bullet would. Expect 3-5k depending on barrel material before un-serviceable accuracy results.

That said, barrels, bolts & extractors are consumable parts and easily replaced on M4 platform rifles. Stock spares based on expected round counts.

I have had a lot of arguments with people over the years about AR's and steel cased ammo. I tried it... I don't use it. I reload my practice ammo which is brass cased and I save the good stuff for later.

The AR pattern rifle was never designed for steel cases and wear surfaces will have more strain and wear than design.

I want to use the very best when push comes to shove. After all "they" deserve it

update from Rock River Arms.
The issue is not the extractor spring. It is the steel cased ammo in the AR platform having different dynamics than brass which causes sticking in a hot chamber.
Steel cased ammunition is not recommended in any AR platform.
