Sorry Guys, should have posted this with the original.

First off, the pistol grip bolt is not messed up. I just needed to find the proper size Allen Wrench that was long enough to easily reach it. The size is 3/16 inch and it takes a long Allen to reach it. But it came off easily. My Bad

Now, the charging handle issue. First picture is the bolt assembly with the charging handle in the "normal" position that it would be in the upper receiver.



Next is an upside down shot of the upper receiver with the charging handle almost in the latched position. You can see the groove it rides in stops way short of a full length charging handle. Close up is a little washed out, but shows the groove better.





The last picture is a side-by-side with a standard AR's charging handle to show the difference in length.



As you can see, the 15-22 charging handle is molded from a single piece of plastic with a pinned latch. Not a lot of meat there and I do not believe it would stand up to even moderate abuse. I will probably try to order a spare from S&W.

Hope this update helps.
