I'd like to build a truly lightweight 3-gun rifle. What's the consensus on cut outs on receivers? This will be strictly a competition rifle, not a SHTF rifle.
Talk to me about your gas system tuning, last round hold open, and the ammo you use, please.if you need to clarify something I've posted, just ask--I'm happy to do so. makes things far more amicable than assuming something I've not stated.
I'm contemplating the cut out receivers to reduce weight.

Links? The last few non-vaporware skeletonized receivers I saw were billet, so they started from a heavier weight. The amount of skeletonizing on some I've seen concerned me as well so I started to look at lightweight forged receivers. I found the following without trying too hard: 1) 2A Arms 'Balios Lite' upper/lower combination - upper is under 6oz and the lower about 6.5oz; 2) V7 Weapon Systems has a slickside upper (no FA or dust cover) with shell deflector that weighs 6.4oz; 3) A run of the mill forged stripped upper with no FA is about 6.5oz as well, but has provisions for adding the port door. A forged no FA upper with mil-spec port door assembly represents a savings of about 1.3oz. A forged slickside upper represents a savings of about 2oz.
Another method to lose some weight, though at high cost per oz IMO, is to shed mil-spec parts with lightened/Ti parts. V7 Weapon Systems has a whole catalog of replacement parts from trigger pins (incl. 0.155" Geissele size) to castle nuts to port doors. What I'm finding is that the place to lose the most weight in one fell swoop is in the carrier.
