I have recently placed more of an emphasis on mounting my scopes level and torquing my bases and rings down to spec. I think that using Loctite is a good idea and based on my limited knowledge, I am leaning towards the purple color. Any input or thoughts?
Have never used purple, have to look that one up for my own education. Blue, it would appear, is the norm, and I use it exclusively for every thing from guard screws, to scope bases and rings. However, before using it, I always wash the screws in alcohol, and clean out any threads with a Q-Tip soaked in alcohol, to remove any foreign material and especially any oil or grease. Never, ever use the RED Loctite unless you want it "permanent". YMMV

I've used red, green, blue, and purple Loctite through the years. I use blue the most frequently since I usually want the ability for easy removal. And I must say that probably 90% of my use is for motorcycle restoration. I strictly use the purple Loctite for very small, fine thread screws or bolts, generally when torque values are listed as in-lbs. Obviously this works great on screws similar to scope mount rings.
I know this doesn't really apply to gunsmithing, but I still use red fairly often on high vibration fasteners like dirt bikes and Harleys. Removing fasteners previously dabbed with red Loctite is no big deal under one major condition-the area must be able to withstand the heat of a torch!
