AMBI Charging handle for M&P10

[Little Creek]

Has anyone found and installed an ambi charging on their M&P 10. I am partial to the RAPTOR, but I can't find one for this format at this time.

Anyone installed any of the ambi charging handle latches? If so, what do you think of them.

littlecreek,

You and I are in the same boat. I asked this same question on AR15.com in the S&W subforum there - and no one has responded with any knowlegde about the Raptor. I guy did post that he is currently using a "Gen 2" BCM charging handle on his M&P10 - but he also knows of problems with earlier gens of the BCM unit.

If I can find a Raptor .308 charging handle - and if the outfit will accept returns if it doesn't fit - I will buy one and report here if it works or not. I hope is works - as I love the Raptor on my 5.56 guns.

cheers

I use the BCM handle mod 4 with a little sanding and works awesome

I had to do a bit of dermal work to get the raptor working in mine.
I have the AR-15 model in my M&P-15. I really like the way they operate.
I picked mine up at: JoeBobOutfitters.com
They give a 5% military discount.

No joy on a drop in fit with the Raptor. Sure - the Raptor does drop right into the upper of the S&W - and cycles smoothly. However the problem begins when you try this with the bolt/bolt carrier installed. Binds up big time.

The hole in the front of the Raptor is a smaller diameter than the stock S&W unit.

The "trough" in the Raptor is just as wide as the "trough" in the stock S&W unit.

There is a small "step" in the Raptor right near the front end where the larger trough transitions to the smaller diameter hole. This is where the problem lies.

There is no step in the trough in the S&W stock charging handle.

Since for me the Raptor is by far the best charging handle - I decided to mod it so it would work. I took a chain saw file and made the front of the Raptor equal the trough, i.e. I removed the step. Then I dremeled it to polish it, put aluminum black on it and PRESTO I have a working Raptor in my S&W M&P10!

Love the Raptor - makes charging the S&W M&P10 so much easier - with either hand.

Hope this helps,

cheers

Did you need to modify it in any way?

Did you have to relieve the "trough" full length or just remove the raised portion at the front?

I don't understand these mix reviews, some work perfect and some don't with out modding..
I just want a new charge handle

Raptor ambi .308

I am going to be performing the modification to my .308 raptor on my m&p10. I will take photos and post by the end of the week. I just want to clarify, do I only grind down the inner trough hump and there is nothing needed to grind on the outer side?

I can't wait for the mod, I enjoy the Raptor on my other AR and being ambidextrous at times when shooting miss it on the M&P10

Try the Raptor handle just as it comes out of the package as it may drop in and work that way.
If not you will probably need to do at least steps 1 & 2 of the following.
1) File down the raised area on the front top so it is flush with the top of the handle.
2) Then from the front, through the hole, use a round file to remove the raised area of the channel so it is flush with the rear portion of the channel.
3)If the handle still does not fit properly you need to deepen the full length of the channel. Mine only needed .010" removed, but others have had to remove as much as .030", which would have made mine awfully thin. this is probably best done with a milling machine and a ball end mill. With lots of patience it can be done with a dremel.
Be sure to try the handle between each of the three modifications.

Raptor ambi .308 mod

Ok so you must remove the hub on the outer top front.

Then you must remove the inner hub in the front of trough.

You must deepen the inner trough almost through the whole trough.

Go slow start with the outer hub, then work your inner trough.

Remove some then test it, Remove some then test it.

Then walla it works.

Be sure to clean everything in your rifle, Make sure you leave no metal shavings anywhere.

The Raptor is a superior ambi charging handle worth the mod.

any guestions? thanks Eddie

...You must widen the inner trough almost through the whole trough. Go slow start with the outer hub, then work your inner trough. Remove some then test it, Remove some then test it....

Just want clarify, you need to make the trough DEEPER, NOT widen it.

Raptor mod update

So on further testing I had to deepen the whole inner trough. Made it much smoother to feel and operation.

 

[eddieisakson]

yes deeper , but to get rid of the full lip on the front inner trough it will require some widening. Also file the upper inner front down a bit to ( just make it all even and smooth). here are some more pictures. As you can see even with these mods you keep the aesthetics of the part and rifle when installed.

After you have it to the point you think is good, Clean assemble, Cycle it a bunch ( Unloaded ). Dissemble and look in the trough. If it needs more filing you will see rub spots in the trough. Work those areas some more and repeat.

 

[eddieisakson]

A good reference for depth is to make sure the bottom front of the Raptor charging handle is flush with the top of the BCG. The picture shows the correct fitting. Hope this helps. It's what I did with a little time and patience, And like someone posted earlier make it deep enough and wide enough and don't do to much you don't want it to thin. File clean test , file clean test.
After doing this mod which I had some trepidation about I would recommend both the Rainier arms Raptor and the m&p10. Looks and feels sweet together .

I just got my 7.62 Raptor in the mail Saturday. I tried to fit it today and it binds. The binding occurs when trying to close the bolt, but not until the bolt is 3/4 of the way closed. On mine it really looks like if I took off the nib on top it would clear enough to function. I haven't decided if I want to cut it and hope it works or just send it back to Rainier. I purchased my M&P-10 in July 2013, not sure what the production date is.

 

[Jwteknix]

Hey guys,
I bit the bullet and bought the raptor. When I first put it in dry, it binded, lubed it up and worked it in, I charged the handle till it moved almost freely took it out cleaned and relubbed. Found the nipple on the top front rubbing, filed the nipple off, cleaned and relubbed, it works great, no need to deepen the valley. Awesome handle, million times better then stock, if you have a scope its a must.
In all I just chopped the nipple off the top, lubed and cleaned it a few times and that's it. So don't go strait away grinding stuff, I really didn't even have to cut the nipple off but, it did help it move easier..
Hope this helps,
James

how much would you charge a fellow m&p 10 owner to repeat this modification? just curious...thanks and Semper Fidelis from a former 0311/USMC.
