I Guess I’m the New Girl

Me and ig at the movies recently. It's a 3D movie, and ig is the guy without the hat on.

Thanks for the offer. I'm building a lightweight AR with Spike's Tactical stripped upper and lower. So far I've also got the enhanced lower parts kit and an 18" barrel coming. Still slowly gathering everything else. Any ideas on how to shed weight? Should I be posting this elsewhere?

Been reading up over at M4C? Despite the cost, for our wet climate I'm considering upgrading all of mine to Neverwear Inconel springs. There's also a spreadsheet somewhere on the Net with parts weights, but I don't remember where and it hasn't been updated in years--PM me your email, and if I can find the copy I was annotating for my briefcase-carry build in twenty-five terabytes of data I'll pass it along.

Welcome to the forum.

Nice meeting you the other day at a TCGC.

And the best way to shed weight is the barrel. An 18" isn't going to be light. A 16" pencil barrel would be a start.

Or a 14.5 with a pin-and-weld, though at pencil you might want a free-float to avoid barrel whip and those can at up most of the savings. If money is no object take a look at V Seven's titanium parts catalog.

Yeah, get this barrel instead...
16" CL - LW - ML - LPGB - SIONICS Weapon Systems
then get a reasonable weight handguard and stock. I'd suggest something like a BCM MLOK or Centurion CMR. Just don't buy into LW BCG's unless you are building strictly a gaming gun intended to shoot low powered, wimpy rounds, otherwise get a real BCG. You just missed PA's sale on SOLGW BCG for $115, but keep an eye open if you're not in a big hurry, they have been putting them on sale quite a bit. Note the specs, I would not buy a BCG without a similar spelled spec list.
Sons of Liberty Gun Works M16 Bolt Carrier Group - .223/5.56 - Phosphate SOLGW-BCG

The barrel is the single most important part of an AR, the BCG is #2, don't skimp either place. And don't do Nickel Boron BCG, if you want an easy clean finish get a SIONICS Np3 BCG (same place as the barrel I linked above), otherwise stick with GI phosphate as specs above.

I also highly recommend the A5 buffer systems, the combination of an A5 with a properly ported mid-length gas system is an unbelievably smooth shooter.

I would recommend avoiding a 14.5" barrel due to requirement to "permanently" attached muzzle device. Do not use a titanium gas block, thermal expansion of the different materials can cause issues. There is no way to avoid barrel whip short of not pulling the trigger, choose a barrel, LPGB and handguard I.D. appropriately, not all are compatible. If you choose a BCM rail, V7 does offer a Ti barrel nut for it, the rest of the V7 Ti parts cost a lot for very little weight savings.

Thanks. It was nice meeting you too!

Also, Arm or Ally usually has black-nitride Toolcraft BCG's for $75--only difference between these and the TC's the Pentagon buys for spares is the protective coating.

Does that make the specs TOP SECRET? A lot of nitride bolts are 9310 Steel, no thanks.

Nitride carrier but C158 bolt if you choose that option. 9310 would be a Hard Pass here too.

Welcome! Personally I like the titanium parts from VSeven. I have tried another, but prefer VSeven. For the rifle grip screw I get the titanium from Mettec, they are at least a couple dollars cheaper than elsewhere. If you build with an Anderson lower you will want the 1/4x28x3/4 socket head screw whereas most of the other lowers accept the standard 1/4x28x1. Link below. With the 18" barrel, you will want to explore titanium muzzle devices - so much lighter. Green Mountain Rifle Barrel (be careful with some of these, for some do not have M4 feedramps and you will need a receiver without the M4 grooves) and Ballistic Advantage offer pencil profile barrels that are lighter as well - gas block journal is usually .625 on these barrels. Go to Sporting Systems to do your build - they have the tools. Make sure your springs are in correctly, especially the the trigger and hammer springs. Plenty of oil on the roll pins, no need to chamfer as shown in many online videos. Take your first build slowly and have fun.

Personally, I don't do Gucci guns, unless you consider ambi-controls Gucci, but I'm left-handed and figure they should have been that way in the first place. If you take into consideration the last place Eugene Stoner worked was Knight's Armament he was headed that way too.
