rodent.22 Posted December 31, 2009 Report Share Posted December 31, 2009 Hi guys. Many complaints have been directed towards adjustable stocks being ''loose'' and ''rattly''. This is true of the Colt/Umarex as well as many other brands. I have come up with a fix that is cheap, easily done and has excellent results. Tools needed are a small pair of pliers (needle nose or duckbill), scissors, adjustable razor knife, unibit or 5/16'' drill bit, and a set of gun files ( flat and rattail). Materials needed are a roll of Oatley plastic hanger strap, 3/4'' X 10', about $3.00 at Lowes in the plumbing dept. This is grey plastic, flexible with a smooth non-stick surface that can be easily cut with scissors and final sanded with sandpaper. Start out by removing the stock, pull it all the way back, still holding the adjusting lever down use a screwdriver to pry the lever a little further down while pulling the stock off the tube. Measure the width of the lock ridge on the tube and cut the grey strapping ever so slightly narrower so it fits snugly inside the stock lock slot. Next cut the length so the strip is the same length as the stock inside. Next press the strip of strapping in place so the lock pin ''marks'' the proper location of the hole for the lock pin to function. Remove the strapping and drill/cut/file the hole. Make it slightly oversize so the pin won't jam when operating the lever. Now assemble to check for clearance. If too tight lay out a piece of #180 grit sandpaper on a flat surface and lightly sand the grey strip to the best thickness to permit smooth operation. A drop of gun oil will smooth it up....The last 1/2'' or so of the grey strip can be trimmed off so it doesn't show in side the stock when it is collapsed fully. !0 to 20 minutes tops for this mod...

techmike Posted December 31, 2009 Report Share Posted December 31, 2009 Hey Rodent - Excellent presentation and fix for that problem. One has to wonder what they were thinking to make it that sloppy! I had some self adhesive teflon that was about .020" thick - I stacked some of that up inside the stock and that did the trick for me. - Thanks! :thumb:TM Quote Link to comment Share on other sites More sharing options...
rodent.22 Posted December 31, 2009 Author Report Share Posted December 31, 2009 Hi TM....I think the clearance issues may be several suppliers being involved in the stock parts manufacture....The rest of the gun is superb.... :confused: Quote Link to comment Share on other sites More sharing options...
techmike Posted December 31, 2009 Report Share Posted December 31, 2009 I don't know - my original stock was sloppy, and the ATI stock I bought was also loose. Seems like a design problem to me.........the "buffer tube" could have been made a bit larger imo.TM Quote Link to comment Share on other sites More sharing options...
imschur Posted December 31, 2009 Report Share Posted December 31, 2009 Part of the problem sounds like an AR-15 with a Mil spec extension tube and a commercial stock.http://ar15tactical.net/pdf/buffer-tube-identification.pdfGreat fix rodent.22.
