Thanks for that. I see what you mean.Some of those rails are short enough to allow you to keep the front post, IIRC.
I know Troy makes similar versions, and I'm sure other companies do as well. Look around and see what you can find-- shop weights, diameters, lengths... even colors, if it suits you! There's so many options in the AR world (including this style of handguard), you do yourself a disservice by not exhausting all of the options.
What kind is it? Any special model?I have a Troy BUIS on mine, and I really like it.
That's what I plan on doing.What Speed said. It's the Troy Battle sight. I don't have an optic at the moment, so I tell myself I'm just getting proficient with irons, lol.
