M&P15 Range Report

[xICEMANx]

Took the new to me M&P15 to the range saturday. This is the "optics ready" model with the 1x9 twist.Tried a few different types of ammo. Did not like Tula steel cased ammo. At all. I'd fire one shot then click. Next round wouldn't feed. Figured it might be the mag(pmag), changed mags, same problem. Tried some brass case AE, not one issue. Tried Silver bear, same issue! My previous AR, Sig, and ACR loved Silver Bear. One thing to note is the previous owner lubed the **** out of the gun before we traded. Like too much. As I continued to shoot I was able to cycle the Silver bear, but still had some FTF's. Brass case was not an issue. I've read the M&P series guns aren't ammo picky at all, so I was suprised. I think it had something to do with the excess ammount of lube. Overall the gun was very accurate and functioned great with cheap AE brass, sold at Wally World for $5.99 a box.

I took it home and wiped off the excess lube. I'm going to give it another try with the silver bear. I have about 350 rounds of this stuff so hopefully it works. If not I guess I'll have to put it up for sale.

Iceman let me know if you put it up for sale!!

If he used to heavy an oil it could very well gum things up, thats why I like my TriFlow

Will do. I'm giving it one more try. Picking up some more brass case this weekend.

I run my AR (M&P) 'wet' and so far Silver Bear runs fine. I use Slip2000 EWL and it seems to like it. I don't keep mine dripping, but I am generous with the lube.

My OR model will use anything including steel cased Russian without a hiccup. It lives on Froglube and cleans up easily compared to the old CLP.

I ran it pretty wet with CLP and no problems, ever. I would check the extractor and it's sping and make sure it is clean. Soft, brass cases are more forgiving than hard steel cases. Of course, feed only trouble is usually mag related but P mags are pretty trouble free.

I am with the guys on this; really clean and inspect the heck out of the BCG- tear it down 100%. Check everything with a light, soak the bolt in Hoppe's for a bit.
I will add, I am hoping he did NOT use a spray in bore cleaner foam. This stuff is sticky, and it absolutely gags a gas tube. If this is a possibility, you need to clean the gas tube as well as the chamber, and that might take a bit of work. There are some skinny pipe/ bottle brushes for this, but Lord help you if you break one off in the gas tube. Soak, spray, air blast out.
A hint for gas tube cleaning: Carb cleaner or brake cleaner. It has a spray nozzle/ tube, and there is no residue. Works wonders for nasty BCG's too. Clears ports very well.
I prefer light oil on AR's. I ran some Frog Lube last week, and found a boat load of soot and mud after only 300 rounds; it looked like the rifle was not cleaned for 1K shots. I feel the Frog lube does not wash away stuff much or chemically cut it; it holds onto grime. Yes, it cleaned pretty easily, but after 650 rounds for the day, the rifle was a mess.
I am switching back to Slip or Tetra oil. They ran WAY cleaner.

The Frog lube holds the grime in suspension, off the metal. You just wipe it off. The brake cleaner washes the grime away too but strips the metal of protection.

IMHO, you want to see the grime and be able to just wipe it away. It means it is protecting the metal as it is designed to do.

Thanks I wiped things down and applied a few drops here and there. I'm a big believer in less than more. BCG looked fine but I will take a closer look.

Well took it to the range again and ran some more silver bear through it. Still had alot of ftf's. When it would feed, the expended shell would be really scratched up. Brass case ammo zero problems and the casing is perfectly fine. Sold the remaning SB I had and just picked up 500 rounds of brass cased 55grain. Not a huge deal to me since brass case is nearly as cheap these days.
