I replaced the pistol grip on my S&W M&P 15-22 with a MAGPUL grip. The two springs that the grip holds in place came out. I didn't know they were there. I reinstalled them with the MAGPUL grip.
Now the SAFE switch works loosely and the pin near it that moves to allow the upper and lower to separate is also loose. Were there other parts that came out when the springs came out? How do I fix this?
Hey Jim,
I haven't taken my 15-22 apart, but in my full size AR, there are two little brass pieces that sit in front of the spring and actually come into contact with the safety and the take down pin. If you check out this picture, (http://www.brownells.com/userdocs/sc...erreceiver.gif) the brass pieces are numbers 11 and 21. Since the 15-22 doesn't have and buffer tube assembly, I believe they are both contained in the grip.
Judging by the date of the last post, i presume that you've sorted this already.
There are two springs and two detents, one for the Safety selector and one for the rear takedown pin... both are needed.
Check youtube for grip swaps on 15-22. That should show you what parts you are missing/lost.
I can confirm these part numbers, as all have been purchased over the last 6 months.
Extractor Rev M1 315430000
Extractor Spring Rev C1 315610000
Extractor Plunger MIM 406130000

I can't really tell for sure what the cost is for these. The way S&W does the invoice the price is not shown. You have to look at the credit card charges and they don't match the invoices half the time. They add a hold then it disappears and shows back up later. I still have items ordered for several months that haven't made it yet.
The S&W certified armorer I deal with can not get the part. His go to person say factory installation only.
Give them a call and see if they will send you one. The worst they can do is tell you no and send the rifle in.
Maybe they have different levels of training and my guy doesn't qualify to get one. (just thinking out loud)
don't need one yet as my rifle is new, but I like to be prepared and have parts on hand for future problems , going to call this week and see where I get
More specifically, if I order parts #s:
- S&w 405020000 b106 22 AR bbl threaded 16.5" rev A
- S&w 404570000 ejector
- s&w 404560000 barrel extension
- S&w 404590000 barrel extension rollpin (x2)
I should end up with everything I need to replace the barrel, correct?
