MI MCTAR-30 End Plate Sling Adapter Install

Vortec MAX · #1 09-17-2016, 01:43 AM

I had seen pictures of this mount on other M&P 15-22s, so I purchased one to try. I was disappointed to see that it moved around and didn't fit quite right on a 15-22 because the adapter is designed to fit over the extension tube lock nut. So I came up with the idea of modifying a lock nut to be a kind of spacer to fill up the void under the adapter. I had the I.D. of a lock nut bored out to 1.15" and had a 0.55" wide slot cut in the bottom of it. You can see the results in the attached photos.

I also had the "nubs" milled off on the adapter as shown. After seeing the adapter installed, I don't think taking these projections off was necessary. I still could not slide the adapter all the way up to the back of the receiver because the fillet at the bottom of the extension tube prevents it.

While I was at it, I also ordered and tried to install an oversize charging handle latch that was designed for a regular AR-15. It did not work. You can see in one of the attached photos that the 15-22 latch has a longer "hook" than a standard AR.

The sling adapter worked out well though. I had to tighten the screw to 18 in-lbs to make it solid.

Nice mod. I just gorilla'd my crossbolt so it doesn't move.

Your solution or much more elegant.

NDZ make a multitude of different latches in different styles and size for 15-22s along with, believe it or not a purpose made Speed Bolt Release or SBR. Both fit and work a treat. Give them a looksee, no need to bend or stretch or fettle stuff to fit, just buy purpose made.

Nice work on the end plate sling adapter. I have ordered a cheapo made in China job, just to try it on my Smith to see if i like it before i pay for a better one. Its only for fun since we cant use a sling in our UK comps!

The Magpul BAD lever needs precision bending in the right place to clear the trigger guard and the mag release which can interfere with the function. It is possible to get the BAD lever to work on a 15-22 if you know the right bends to make.

Rob1 has it right though, for a no hassle solution go with the SBR by NDZ custom made for the 15-22, i got the BAD because the SBR is ITAR controlled and i am a Magpul fanboy...(not)

Thanks. I had never heard of NDZ before. I just checked them out. I will be ordering their Speed Bolt Release for sure. I found an ambidextrous charging handle with oversize releases made by Next Level Armament that I am considering, so I might not get their CH release lever.

That turned out well. Did you have to heat the aluminum before bending it?

I had mine pre-bent before purchase, here is the original link...scroll down to Straightshooters description of how to make it fit.

I am hopefully posting some pics of my cheapie evil bay end plate sling adapter, It came with a quick detach sling loop and an alan key, and yes before you tell me its on back to front i know it just fits better that way until i can purchase a castle nut and complete the mod like the one posted earlier. Here in the UK we cant use the slings in competitions so its just for a bit of fun really. Tbh i was really surprised at the quality of the item i figured for the amount i paid it would be going straight in the bin! In total it cost me £3.75 inc p+p all the way from China
