SUNWAYFOTOSUNWAYFOTO 5.51 inch M-Lok Arca Rail Mount Adapter Accessories for Arca-Swiss Tripod Head Aluminum SMP-140

I purchased this mlok ARCA Swiss rail to attach to my MDT Aluminum Chassis for ease of use of bi-pods and tripods featuring Arca Swiss rails mounts.. These mlok ARCA rails allow you to position your MDT Aluminum Chassis anywhere that you desire along the rail section to find that perfect balance point for consistent accuracy.. Perfect ARCA swiss rail for the price, but will probably upgrade to ARCALock rails in the future for added stability and gripping pressure.. With all mlok attachments there is zero wobble or chance of misalignment once installed and torqued properly.. A great investment for all MDT Aluminum Chassis users, be sure to order the correct length..

Part fit just great no issues at all

Excellent chassis interphase for an arca tripod.

This is an excellent piece of equipment. It's extremely well made and came packaged like a piece of jewelry. I purchased it to install on my Bergara B14 BMP. It fits beautifully, but make sure you loosen the screws enough so that the cross pieces will engage the M-Lok. Also, don't guess which length you need; measure the total length of the slots. That way you won't have to return a rail that's too long for your application.

Beware that if your rifle does not feature full length ports of mlok it might not fit and requires sanding work (mine is a Christensen arms MPR)

I bought this to mate my rifle to my tripod (really right stuff head) and there was to much movement (adapter plate fit, but was small and allowed rifle to slide). I contacted Really right stuff and they said there is slight variance between manufactures. To ensure you get a tight fit purchase the same brand components (head, adapter plate).

Great little mount. I have this mounted to my AR-10. Locks up nice and tight with the M-LOK mount. Seems very well built, sturdy aluminum. I love it. Will buy another for my AR -15 as well.

Seems to be within spec. Some cheap Chinese pic rails I’ve bought have been too narrow for example and you couldn’t mount anything solid to them. This seemed fine. No complaints, and a good price. Took a whitetail at 238 yards off a tripod with it this year.
