that is the question. Whether 'tis nobler in the mind to have a pure lightweight carbine, or to suffer the slings and arrows of weights, protruberances and complications like a BUIS...

I've built the lightest-weight carbine that I could, with a slab-side flat-top upper and a BM ultralight 16" barrel. I topped it with an ACOG TA31-f.

I'm going to grind off the bayonet lug as a final touch, and am very tempted to cut down the front sight base as well. Any arguments for or against?

I wouldn't.

Find a clamp on lo-profile block (looks like a straight tube ontop for the gas tube). Reason I say clamp on, is that some gas blocks won't be predrilled for pins to hold it on the barrel. If you can find one that is, it might not be properly aligned with the barrel.

When I first got an Eotech, I decided that I didn't like the FSB being in the sight picture, so I cut it off and mounted a BM folding sight that clamped around the gas block that was left. I absolutely hated it.

If you have a mil spec one, I'll trade you. I just cut down, shaped and parked a FSB. No cold blue here. Turned out great.

Turns out CMMG FSB's are not mil spec. The slots in the barrel for the tapered pins are not slots, they are holes. I think they drill the FSB and barrel at the same time (with the FSB mounted).

I now need a milspec, uncut FSB and I have a modded one I can't use.
