The troy seems to be built like a tank.I have 2 versions of the GG&G MAD and love them.Eventually ill have the troy too as I like variety.I have the MAD,Matech,and ARMS#40 and a #38 swansleeve.I do notice this though I get a better sight picture with the Matech as the peep hole is 5/64 and the rest on the small arperture including fixed handles and removable handles is 1/16.
I drilled out all my small arperture to 5/64 and they are more accurate and easier to hit with and sight in on than before.GG&G has great CS.I bought my 6 arperture ranging disc model and standard MAD used.The clamps were a bit bent so I called GG&G..they send me 2 new clamps and bolts at no cost and told me they waruntee thier products 100% new or used
.
The thing I like about the Toy is its a same plane sight no matter wich arperture you use and that goes for the MAD as well.The A2 GG&G will mimick a standard M16 sight choice wich is not same plane.The MAD I think is just about if not the lowest profile BUIS out there.For that money though I would get the troy BUIS.
