Help me decide

[Thorsen]

Can't decide on which BUIS I want. Trying to decide between the Troy rear folding battle sight and the Arms#40L-SP.

Which one would you guys prefer to have?

I have both, and I prefer the Troy. Simply because of the method of deployment.

A few differences between them:

- The Troy's lower when folded by a good bit, and will fit under more scope/mount combos.
- The Troy flips with the large aperture deployed, the ARMS 40L with the small aperture deployed.
- The Troy's windage adjust is much stiffer and the knob is shrouded, which makes it both harder to adjust and more resistant to getting moved accidentally.
- The Troy locks in the up position, and the Arms is spring-loaded but not locked up. If the ARMS gets knocked, it gives and springs back into position, however, if it gets dirt or something in the mechanism, it can stop it from going all the way up.
- The ARMS slides on over the rail, rather than fitting from the top, and has to have the cross-slot screw/recoil lug completely removed to go on. The Troy fits from the top - I don't know if it'll fit when loosened or if the clamp needs to come all the way off.
- The ARMS locks in the down position, and you need to flip a small, rounded, low profile lever to allow it to flip up. The Troy doesn't lock in the down position, and can get knocked into partial deployment.

Figure out which of these is important to you, and it'll be clear...

I use Troy on all 3 of my rifles.
