Random project idea...building an AR packed with as many AWB-list features as possible.  Why?  Because inducing freak outs from leftards is hilarious.

So...what features/parts to use?

For starters, you pretty much have to use the Spike's Tactical Snowflake lower, with selector positions for Safespace, Triggered, and Full Libtard:  https://www.spikestactical.com/products/snowflake-lower?variant=93291479063

And since folding stocks and collapsible stocks are each scary by themselves, then a stocks that is both folding and collapsible must be at least twice as scary.  Therefore we're going to need an AR folding stock adapter:  http://www.primaryarms.com/sylvan-arms-ar-15-folding-stock-adapter-arh100?trk_msg=TJD76T3MDO64PAPI0M3QEU7CA8&trk_contact=F6RQDR5TUQMOARG0J3IM6F3APK&trk_sid=770J3TTVSA3LDCS0CGLAIT1QMG&utm_source=listrak&utm_medium=email&utm_term=SLOT_5&utm_campaign=18_06_Ad_31_Indepedence_Day_Part_1

Add carbine stock buffer tube and stock of your choice.

Not sure if it's possible to have a bumpfire stock that folds and/or collapses.  Pretty sure nobody makes a top folding stock adapter for the AR, so I don't think you're going to be able to go full "shoulder thing that goes up."

Pistol grip is easy, vertical foregrip is easy, 'flash hider' is easy.  Preferably a flash hider that also serves as a QD mount for a suppressor.  And the suppressor, of course.

Barrel shroud...IOTW, handguard, also easy.

Now, does anyone know if it's possible to combine a bayonet lug with a free float handguard?  Or do you have to use the classic A frame gas block and government handguards?

Of course, if you go with the classic barrel nut and barrel profile (M4 or M16), you can add a flare launcher (that at least looks like a grenade launcher):  https://www.brownells.com/shooting-accessories/duty-gear/safety-amp-warning-equipment/m203-37mm-launcher-prod118458.aspx

Alternately, if you want to spend the $$$, you can apparently actually go full chainsaw bayonet:  https://www.panaceax.com/weaponized-chainsaw/zxcb-chain-saw-in-flat-black

So, what am I missing?

I need that chainsaw bayonet. It's so stupid, I gotta have it  .

Langenator - I have a rail top gas block with a bayonet lug, so they're out there... not using it, or the free float forearm that goes around it, if you're interested...

I like my TBRC A-Salt lower.

Whichever way you go, Cerakote it like the Confederate Flag just to make sure.

Hmm, I'd like to do that with a throw together build uo.

Maybe find some kind of muzzle device that looks wicked too

And yes you can, if you want retro the rra sleeve fits the government guards.

I got it on my true disspator build.

However the rra sleeve isHEAVY

I have one on my service rifle build.  I don't recall if mine is the Compass Lake or RRA version.  I think it is the RRA, but they are equivalent in function.

HeadlandRam is spot on that they are heavy.  And they weigh a lot too.  Great for a dedicated target rifle.  Terrible for actually carrying anywhere.
