Hello, new member here.

Hi,
Just joined today, I have two S&W's a M&P 40, and just purchased an M15T. Took it to the range this morning for the first time, got all setup, chambered a round fired , nothing.
Checked there was a round in the chamber I removed it and found the primer was never contacted by the pin, chambered another , same thing packed up and left. Using American Eagle
5.56 ammo 55 gr FMJ ammo
Any suggestions?
Thanks

welcome from Washington state...I am not one of the experts here but am sure you will get some feedback for your problem

Is the rifle new or used?

I would give the bolt carrier group a cleaning and inspection. Here's a quick tutorial. https://www.youtube.com/watch?v=JmQZZlQCTHw&feature=youtube_gdata_player

The gun is brand new first day at the range, it has to be either a stuck or broken pin but I am not going to mess with it. going to the Smith tomorrow
Thanks

Welcome to the forum.
Have you finished inspecting the bcg yet? Keep us updated please.

It might be as simple as a foreign object obstructing the firing pin. Watch the video, it's a less than 5 minute inspection.

Thanks again I watched the video very interesting and looks simple to do I think I can handle it may be I will give it a try after I get over my frustration

Nothing more frustrating than a new firearms that doesn't fire on day one. Make sure it's thoroughly cleaned. Many times there is shipping grease that needs to be cleaned out. That causes a lot of problems and who knows, could be impacting the movement of the firing pin. I don't think it's likely but that could be the case. Best of luck.

Two pulls of the trigger, two different rounds of ammo, no impact on the primer. Field strip the bolt carrier group. Double check that all BCG parts are present, clean, and properly lubed. I bet that something is causing the firing pin to drag. While you have the BCG out, give the entire rifle a quick inspection for anything glaringly out of normal, give it a quick clean & lube.

If it fails again at your next range session, stop trying to shoot it. Find someone locally who is knowledgeable and can help diagnose the rifle. If that fails, call S&W customer service for repair and a shipping tag.

Either BCG or maybe fire control group. Check BCG first. you will want to learn the inner working of you firearm so don't be afraid to watch several videos on how they work I say several because some aren't all that accurate and you'll want to know how to strip and put it back together in case you break a spring or hammer in the FCG anyhow.

Very disappointing when ya get something new and it doesn't work like it's suppose to. Good luck and it might be faster to repair it your self.

And a warm welcome from "wild and wonderful " West Virginia at least that's what they tell us.

 

[BillK01]

I agree with the other folks. You'll need to learn how to remove, disassemble and clean the bcg anyway. Might as well do it now to verify it's not just some minor issue.

Hi again
Stripped it down nothing out of order at least to me, removed the pin, looks good moves freely in place, assembled it took it down to the basement and loaded a used shell with a new primer , put the muzzle in a roll of carpet padding pulled the trigger nothing, here are a few pictures. Does the pin look forward enough to strike the primer?

 

[Carrot]

Okay, when chambering the round, are you letting the bolt slide shut with force? It should slam shut, released from all the way back. Just like a pistol.

And lube it well. The bolt carrier looks dry.

Maybe the bolt isn't locking into full battery. At the range, chamber a round by allowing the bolt to move foward on it's own do not ride the charging handle. With just finger pressure, depress the forward assist. Do not hammer on the forward assist with the palm of your hand. Try firing the round.

I'm not an armorer but...

1. Maybe the firing pin is defective; somehow the tip broke? Pull the firing pin and post a picture of just the firing pin

2. Maybe the hammer spring is broken, not allowing enough force to drive the firing pin.

3. Headspace issue.

If it does not look to be #1 or #2, then call S&W customer service. Calmly tell tell them the issue you are having with the rifle. You have a 1 year warranty on it. Politely request diagnostic repair service, a RMA, and a pre-paid shipping label.

It could be a combination of things. Maybe there's an issue with the locking lugs on the bolt and the barrel. Maybe there's a misalignment. Maybe there's a burr on the inside of the firing pin channel. Maybe it passed the factory test fire, but that test fire was the genesis of the issue.

Are those metal shavings on you bolt?
The bcg does not look new with all those scuffs.

You may be right on the release of the bolt I don't let it go forward on its own it may not be engaging the rim of the extractor groove and putting the pin close enough to fire off
I will try it tomorrow. I just let my handgun slide go by itself
this is my first ar and was not to familiar with it
Thanks

Lock the bolt back, place the mag in, hit the bolt release, allow it to move forward on its own. See if that works for you.

In general, you want to let the action on an autoloader chamber the first round the same way it will with subsequent rounds. From the magazine, with full force from the slide/bolt.
