Latest Serial numbers on 15-22

Yesterday, I bought DUA002X. I haven't made it to the range yet but it's sure a fine looking rifle (complete with flash suppressor).
 
I purchased my 15-22 about a month ago. It's S/N is DTX31XX and it had the flash suppresser on when I got it so I'm thinking its a newer manufacture. Before today it has run fairly well with only a couple issue with about 400 to 500 rounds through it. Today at the range I had several instances where the rifle did not cycle completely. The spent rounds did not eject properly because the bolt did not travel back far enough to reach the ejector. At least I think this is what happened because the bolt did not go back and reset the hammer. I have been using Federal bulk exclusively from the start with this problem just happening today.

Has anyone else had this? I have read a number of post here and the FTE's are usually the result of the ejector not being aligned properly. Mine seems fine, just not enough force to move the bolt back all the way. (Maybe just a couple bad rounds in the box and I found them today.)

I was also wondering if anyone knows what the difference is between the silver springs and the blue springs. Is one type stronger or weaker than the other? My rifle has the silver but it seems most newer ones have blue or blue springs are installed after the S&W rework.

Thanks in advance for any help.
 
Mine is a month old also and the serial number is DTX5XXX. After a little over 200 rounds, I had FTEs resulting from a missing extractor, pin and spring. Sent it back to S&W this past Tuesday.
 
Just picked mine up today. S/N DUA48XX. No star on the manual and the revision is 032210. It does not recommend Remington or Winchester Wildcat ammo. I wont get to shoot it until next weekend.
 
Latest Serial Number 15-22

Just found and joined the forum. Ordered the CA model 811032 yesterday sight unseen. It is Serial# DTX5***. Will pick up 4/12 and shoot the same day.

Thanks for all the good posts, observations, cautions (Safety forcing), etc. All this should save headaches.:D

Figure on putting Federal and Winchester and some 20yr Federal Classic HV rounds for break in. Will go a little slow for first few rounds, snaking about every 5 shots for the heck of it.

Will let all know results.

I've shot both out of my DTX1xxx and I didn't have a problem with either. Next time I go shoot, I'm going to try my luck with remington subsonic.
 
My buddy has his FFL and drove to his warehouse yesterday for me. Picked it up today, I got the threaded barrel model and the Serial# is DUAxxxx No star on the manual and blue springs in the gun. I paid $407 otd after taxes and transfer. BTW first post here on the forum and glad to be part of a good bunch of people with a lot of helpful info!

Excel welcome to the forum and the disorder. You have made a good pruchase and found a good bunch to share the fun with. :D
 
I picked up mine three weeks ago. Serial Number DTX9xxx. It has the blue springs and the updated manual
 
Thank you. So far so good. I had one failed round out of the first 200, but I think that was due to the ammunition. It was Federal, as recommended, but didn't seem to be an ejector issue.
 
Two new rifles picked up today...DTZ0**** and DTZ2****, both with blue springs and 3 upgraded mags each...SC
 
Got mine on Monday. She's a DTZ2***. Blue springs and threaded barrel. Can't wait to go spend some money.
 
I purchased one on monday from a local shop. DTZ5, blue springs threaded barrel, I am taking her out on Saturday.

Question how do you know what gen your mag is?

Latest serial numbers

I just ordered my M&P 15-22 from Davidsons on wed.morning , should have tomorrow . Email I recieved from them states that it is a DUA serial number.
 
I picked mine up from the BX at Nellis AFB last Sunday. S/N was "DUA" and the magazine had the red follower, also, the spring on bolt assembly was blue. Went there today to pick up some ammo and they are now carrying magazines for the M&P 15-22...so I had to get an extra!
