Troy Industries- the Good, the Bad and the UGLY
Good: I have three of the Troy Folding Battle Sights (M-4 and HK). THEY are GREAT! But something you may be interested in is under UGLY..
Bad: I purchased a set of the the new HK 45deg. Offset Folding Sights even though there were few reviews so here's one; The upper portion appears to be the same but the similarity ends there. The sight base and the picatinny rail mount are different. The base attaches to the rail mount with a single counter-sunk screw and the rail mount has a snug fitting relief that the base slides in for stability. The rail mount is one piece with two cuts to allow it to flex slightly, clamping onto the picatinny when the cross screw is tightened.
There were two problems encountered with these new sights. (1) The countersunk mount hole in one of the mounts was slightly offset causing the base to ‘tweek’ and not tighten down properly within it. (2) The tolerance on the picatinny cut made in the mount was so close it barely squeeked onto the upper receiver and was wa-ay too tight to fit on a SLR Sentry 7 Railed Gas Block (quality stuff). The picatinny mount is aluminum and rigid to the point it could easily crack in the relief cuts if one attempts to spring it outward to fit onto a tight picatinny. If you are LUCKY, you will have mounting points these will fit onto. If you are NOT lucky, it is possible to make judicious use of a file to coax corrections to these sights but the anodizing is top quality and going to fight you all the way. REALLY?: Who wants to drop a couple-hundred bucks for something that has to be rebuild to fit?
