S&W M&P 15-22 Ambi Charging Handle

Received 15-22 Ambi Cdharing Handle

Just received the 15-22 Ambi Charging handle from Ground Zero Precision. Dropped it in and made several cocking tests on my S&W M&P PC 15-22. No initial issues at this time. Will range test on Monday. Will post results.
 
Is the charging handle you received the new one made by next level armament?

Tested 15-22 Ambi Charging Handle

Tested new ambi charging handle from Ground Zero Precision at the range today. Fired appox. 100rds with no issues. Very happy with purchase.
 
I have a pair and they both drag. Next Level Armament has been extremely cooperative and are working on the issue. They have updated the drawings and the size of the cut underneath and are almost ready for testing.

Excellent!!

Mine is doing the same thing and only when it get real dirty. Put the OEM or Tacticool handle in and issues go away. You can see on mine where the metal has worn away from scraping.

Hopefully the widen channel will help.
 
Sorry you are correct, I thought Ground Zero was the manufacturer. Next Level is the unit I have and am very happy with it.
 
So for those of us that have already spent about 60 bucks on one of these what are they going to do? Mine had no packaging or anything else included with the shipment. Not that any instructions were required. Apparently the 5.56 version tears up your lower. Was going to get one of those until I read that.
 
Those ambi charging handles are the nicest ones for the 15-22 available.
(From your favorite online retailer)
The only AR-15 thing compatible with the 15-22 upper is whatever mounts on the picatinny rail.
You need an adapter for the hand guard.
The 15-22 A-2 front sight slips right on.
 
I was looking at the 5.56 version for my ar15. I should have made that clear. I already have the 15-22 version from a certain online retailer
 
Ground Zero Precision charging handles for the 15-22 are JUNK! they do not work! Customer service goes hand in hand with their product!
 
Why? Bought mine from tacticool and it doesn't work very good. Was not made by you as far as I can tell that's why I didn't mention where it came from in my original post. It's nice but they forgot to put in the bevel above the bolt that the factory one has. If that was there and the bolt channel were slightly shorter it would have been a homerun. I know rack the bolt and let it go, but some of us live in the country and don't just shoot at a range so when there is a nearby pest they hear that. Guess that's why I have a savage .17 hmr. At least that ones accurate out of the box
 
Pull the bolt back and engage the bolt hold open. Then try to slide the charging handle in and out. Mine will barely move without force. Maybe my upper is out of spec, but it works fine with the stock charging handle. I can use a die grinder and make it work but that shouldn't be necessary on a $60 add on part. Should be perfection for what it cost
 
Can tacticool22 comment on whether or not the tolerances of the NLS charging handle have been modified to allow it to slide freely when the bolt is held open?

I'm weary to install any metal components into a polymer receiver that aren't machines perfectly.
