I made a small adjustment to my Steyr. I was always concerned with having an adjuster that was exposed and therefore capable of being' unintentionally' adjusted. I designed a cover which I had 3D printed and inserted brass inserts into the trigger shroud. I can now still reach the power adjuster, but it needs the cover removed first, before an adjustment can be made. Just makes my rig a little more secure. Let me know what you think. Cheers Z.
