Just finished up with a version to get the reverse stretch up just above 29" overall length. Extension for the A2 is about 5.75" to get there, perfect for those of us who prefer that "extra" length of pull
Also started a version for my HK53 clone (started life as a Vector 93 pistol), which also works on the HK91.
Next up my MPX (stamp due any day now!) and gotta get on that Tavor!
Very cool design
