awesymoto Posted March 2, 2011 Report Share Posted March 2, 2011 well my black MIAD came in for my 308 SASS... i've read on the inter-web that it fits up fine without the grip wedge no mods. Well for my rifle..> wrong. the two detent springs were an issue. the front spring (safety lever) fit up fine with the hole, but the 2nd (takedown rear pin) spring did not sit on the tiny ass shelf that the miad has. Solution? Drill out a wee bit of material to create a pocket for the takedown detent spring to sit in. Now it works fine, however just wanted to clear any miss understandings, the MIAD is not a Plug and Play grip, unless i missed something.....

Robocop1051 Posted March 2, 2011 Report Share Posted March 2, 2011 The grip wedge is only needed if you use the large or medium back strap. The thin back strap fits fine. As for the take down pin detent spring, that is a common issue almost all builders have run into. Many of us have resorted to threading the small hole, cutting the spring, and installing a set screw to hold the spring in place. Mega Arms does this in their MA-TEN. I did it to a JD Machine 308. If you use the larger backstraps from the MIAD grip, and it fits without the wedge, some light sanding/filing might be needed to sit the grip against the receiver better. The slightly wider curve of my 308 needed a bigger seat inside the backstrap before it sat perfectly. Quote Link to comment Share on other sites More sharing options...

308reloaded Posted March 3, 2011 Report Share Posted March 3, 2011 I am lazy and don't want to take mine apart, but if you measure the hole dia. you can then use this charthttp://www.shender4.com/thread_chart.htmspring should be easy to figure. how deep is the hole, set screw length, ::) Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted March 3, 2011 Report Share Posted March 3, 2011 I hate to admit this... but I'm the last person to ask. You know all those stories about people learn from trial and ERROR. Yeah, that's me.First I snapped my tap off inside the receiver while threading. After I bought a tap extraction tool and removed the broken bit, I bought a new tap and finished the threads. Next I tried putting the set screw in, only to find out that my set screw was the wrong size (really hard to tell when you are dealing with such small parts). I don't know if I was mixing SAE with metric or if the screw was too big... I'll never find out becuase the allen set screw stripped. When I tried to use pliers to unscrew it the set screw crushed and broke off. Since the detent and spring were already installed behind the siezed up screw, I just dremmeled off the excess and left it alone. A small dot of Aluma-Black hides the truth.As for cutting the spring. I just measured the spring against the length of the set screw, and cut off an equal amount. It's not an exact math, but it all works.While the whole process sounds sloppy, it actually turned out pretty clean in the end. Quote Link to comment Share on other sites More sharing options...

awesymoto Posted March 4, 2011 Author Report Share Posted March 4, 2011 to try and put some info in here, i just tapped and set screwed the rear takedown spring. i used a 1/8"th inch long set screw threaded 4-40. The tap fit perfectly without a drill bit needed. cut the same spring as the screw length. locktite and whala!! Quote Link to comment Share on other sites More sharing options...

6132expert Posted June 16, 2011 Report Share Posted June 16, 2011 OK, I got around to getting my maid grip on yesterday ( that I have had sence march ). I did just as stated above. I tapped the hole with a 4-40 tap and used a set screw that was 1/8" by 4-40 and worked perfict. That is good info and should be put in a thread and made a sticky.
