MP10 Charging Handle marks

Just a thought guys - what about using a proper size (or as close as possible) chainsaw file to clearance the channel?

Possible, as Tacticool stated, but difficult, even for those that use files on a daily basis. A rattail file may work better than a chainsaw file.
I have over 50 files, all slightly different, that are used for specific situations. My college bench metal class instructor, mentioned previously, had well over 150 files in his tool box at school. At home he had even more files, I would guess he had 300-400 files total, all slightly different. He was a master at making any gun part from scratch, even if it was missing and he had to invent/design the part. He mostly used bench tools and methods instead of machine tools. He learned his skill in England as an apprentice in a shop who did piece work for Holland & Holland and other English arms makers.

Tacticool, If I purchase a charging handle and it doesn't fit, will you be willing to modify it for a small fee?
Thanks James

James. I would, but machine time is expensive and it would run almost as much to modify the charging handle as it cost to buy. They know what changes need to be made and I am hopeful they will make some M&P-10 specific ones soon.
The more people that let them know they would be willing to do an exchange, the more likely they will get on it.
The program changes are super simple. There just needs to be enough demand for them to make a bunch of stock.
 
Finally!

Oh happy day - it works!

The problem is that the channel in the MP10 charging handle is much deeper than the Channel in the Raptor. All other dimensions (except for that nub at the end) appear to be the same for all practical purposes.

And here's all it took for me to do it....

(Warning: to find anybody less mechanically capable than me you'd have to advertise on the Internet. So if I can do it, I can't imagine who couldn't - BUT, there definitely is the potential to mess up your expensive new non-fitting Raptor charging handle.)

1. - Dremel tool
2. - Dremel bit #100 (it has a round 1/4" diameter head)
3. - Patience
4. - Patience
5. - See number 4 & 5 - repeatedly

First - I removed the nub on top of the charging handle using a small file.

Second - I took the Dremel and "slowly" proceeded to deepen the channel in the charging handle from the front end (end near the barrel) for a length of about 4" or so with the charging handle secured in a vise.

Third - I put the charging handle and bolt back in the upper and checked to see if I was making any progress. Still binding? Back to the vise.

Fourth - I repeated the second and third steps over and over and over and over again. There's where the patience comes in.

I was more concerned about ruining the new charging handle than I was with getting the job done quickly. Likely anybody else could have done it faster, but it works and that was the goal. YMMV.

Now it's what I wanted in the first place.

Rainier should either make one of these specifically for the MP10 (like Tacticool has suggested), or state on their website that it probably won't work without modification.
 
hey guys emailed rainier and this was their reply

Hi,

I'm sorry but we won't be making one specifically for the M&P10. Quite possibly in the future we might redesign it so it'll compatible with that platform also, but right now it is not in the works.

Hey man,
Interested in a raptor ambi charging handle for my S&W M&P-10, but have heard of fitment issues for the 7.62 handle. I was wondering if you guys will be making a M&P specific charging handle.
Thanks a lot,
James Audenried
 
Hey guys,

I ordered a Raptor 7.62 and will be modifying it myself. I am a German Tool & Die Maker and have access to all types of machines. I am willing to do the mods for anyone for a reasonable fee. I cannot give a quote until I do the mods to mine so I can estimate the time.

meef,
this is the route we will probably take. Thought I had a couple of local avenues for the machine tool route, but neither looks like it will pan out.
My son thought this would be the easiest route anyway. I'm trying to teach him to get things done with the resources at hand, instead of the ideal/perfect route that is easy. Learning to improvise and adapt is much more a useful life skill than having things handed to you.
He is in Civil Air Patrol, and that has been a huge plus for his life and ours. CAP teaches discipline, respect, and
responsibility, and has influenced the way my son looks at things, mainly for the better.
 
prairie. Civil Air Patrol is a fantastic organization.
I was a member for a few years and it helped cement my desire to join the Air Force.
 
I finally modified my raptor charging handle today. I did the modifications on a manual milling machine. There is 3 different set-ups involved. Mine works great. I would do the modifications for anyone that is willing to ship to me for $55+ shipping.
 
You guys must have a different M&P10 than I do, cause the Raptor Charging Handle I bought works flawlessly as is.

The date should be on the box.

What box?
Could there be bootleg Raptor ambi charging handles on the market?
Our 5.56 and 7.62 Raptor ambi charging handles came in a plain plastic zip lock bags, with no instructions or literature. They were purchased from reputable, but different suppliers.
The 5.56 dropped in and worked fine, but the 7.62 needs modifications as discussed earlier in this thread.
 
Charging handle wear marks on a lower are akin to cylinder turn marks on a revolver. It's either from use or handling, but either way, it isn't hurting anything.

Unless it's a high dollar, one-off and/or irreplaceable firearm, it's not worth fretting over.
 
I was asking Vfin what the production date on his Gun/Box, because he said his Raptor worked as did mine. Maybe there was a change in the upper.
And I fixed the Question. Sorry wasnt very clear.
