Bushmaster M17s "double-tap" PROBLEMS!

Has anyone any experience with this problem? Occasionally, the weapon will fire 2 or 3 rounds downrange with a single trigger pull. It happens very randomly. Throughout a 20 round mag, 7-10 shots will be singles and the rest will be multiples.

I have disassembled and inspected the lower end and cannot find any worn or broken parts. Once the sear(30-417) releases the hammer(30-413), the disconnector(30-418) is in the correct position to catch the hammer upon its return to the cocked position. The disconnector spring(30-419) is in place and is intact. The entire "ignition" assembly is free of carbon, and operates smoothly without any hung-ups. When the lower is separated from the upper for inspection, and the trigger is worked and the hammer returned manually everything seems to be operating correctly.

Does anyone have any ideas why this could be happening?

If I have to, I'll take it to a gunsmith to have it checked out, but I don't believe many in my area are familiar with this gun.

Bushmaster's repair dept. was NO help! They basically said, We don't make it anymore, We don't carry parts for it anymore, You're on your own.
