Please be patient guys… I’m just learning how to walk… Anyhow, I was trying to test the extractor by pulling it away from the bolt. It’s suppose to snap back… I could not get it to budge. I didn’t use any tools, but I was unable to lift it away from the bolt. This is on a new m&p, never fired. I’m just trying to get it ready to take to the range.
Is this normal?
Just take the gun to the range and shoot it.
I dont know the specs on M&P15s but that probably has to do with the stiffer spring/inset they have in there.
Id be more worried if it were soft and easy to lift.
thanks guys… I was going through the assembly guide v2, and it suggests to test the extractor tension. Pull it out, should snap back. Since I couldn’t I thought their may be an issue. I guess the stiffer the extractor the better. I should have a sight next week.
Have you fired the gun yet? Are you having extractor issues? If not, lube the “bolt carrier group” until it looks wet to the touch, then go shot the crap out of it. A good breaking in will “Proof” the weapon as reliable, IF, nothing goes “Tango Uniform” during the process. If it can go through 1000 rounds in a few days (in a weekend preferred), reliably, it should be GTG for a carbine class. If not a lot of ammo or time, I broke in 2 ARs, shooting 250 rounds every weekend for a month, periodically breaking it down and inspecting it for defects (Not cleaning it), a function check, re-lube, then back to the range until I reach 1K. YMMV.
Thanks Mr Harris… I haven’t shot it yet, waiting on sights. I put a light coat of tetra grease on the charge handle, bolt and carrier bearing surfaces and rem oil so it should be ready to go. Thanks again…
Can I ask where you are putting the Rem oil? I personally think it evaporates leaving no lubrication. Might be ok on the external surfaces, but that is the only place I would consider using it.
Have fun shooting it.
I put tetra on the bolt, gas rings and added a little rem oil inside. tetra grease on the bearing surfaces of the carrier group. I’ll probably pick up break free this weekend. So… rem oil is not recommended for an AR?
Normal. If you can move it easily with your finger then it needs a new spring and insert.

Thanks C4. The S&W manual had an inset that displays a test for extractor tension. I called S&W support, the tech said it is normal, he said he nearly broke a fingernail testing a new bolt. About the same here… Thanks again, I guess this is a closed issue now…
no, rem oil is not recommended, at least not on the BCG.
Not only is rem oil a bad idea, so is CLP/BF.
C4
CLP a bad idea? Please explain.
Yes. Do you know the history behind CLP?
Simple question to ask yourself, how can something clean and lube at the same time. When you clean something, you remove the oil correct?
C4
In other words, use a cleaner for cleaning, and a lube (of substantial quality) to lube.
Not that hard to use both products, and works better.
yeah, but tons of people, including the US military, have been using CLP for years, and it works, perhaps not as well as other products, but saying it’s “a bad idea” is ridiculous.
I think this is turning into another lube thread all of a sudden. CLP will work. Just, if you are not at WAR, and have time to clean, it is better to use a product dedicated for the individual tasks.
Of course, I could start a MOBIL 1 tangent:p
Do you know why and what CLP was designed for??
As it was designed, it works well and is a “good idea.”
Just because other people (that might not know any better) use a product does not make it a good choice.

If I remember correctly, my M&P came with the O-ring on the extractor spring. So I wouldn’t expect you to be able to get any movement on the extractor. It was a BEAR to get the pin back in. Next time I take it apart, the O-ring is coming off.
Thanks guys, so since Break Free is CLP, I shouldn’t use that? Should I be looking for Slip2000? Seems to be quite a few differing opinions on this.
Thanks Jepp for the heads up on the extractor…
