You cannot buy a semiautomatic rifle in 3 days in WA. There is a minimum 10 day waiting period.

You could buy the pieces and build it yourself, but you'd need some tooling.

Yes, you're correct and it's a good clarification. Thanks. The rifle in this photo is definitely purchased and would've been subject to the waiting period you mention.

I was being a being a bit sarcastic about his gear being brand new and forgot about the relatively new laws as part of my joke. :)

True, I'm being needlessly pedantic here :)

And who knows, they could have bought the parts and assembled it, if they can find things in stock somewhere.

Looks like a completely stock S&W M&P 15 Sport II, 16” barrel, GI style mag, collapsible stock, plus a cheap airsoft optic.

M&P 15 is a complete knockoff of US military M4/M4A1 carbine, except barrel is longer and has no full auto function to comply with regulations.

Way too boring configuration to build from parts or build out of an 80% blank, and also probably not an airsoft.

Disclaimer: I’m an airsofter outside US at best in the context

What's the waiting period on rifles looted out of stores, cop cars, and police buildings?

You got this backwards, an M4 is actually a knock off of the AR-15. That is to say the AR-15 came before both the M16 and the M4 and both of those guns were built from the AR-15.

>>tekkni+Vo4
I mean that pictured gun is an M4gery isn’t it

>>numpad+Rv4
Sure? If you mean it's probably a 16" with a carbine-length gas system, tube-like handguard that probably isn't floated, and a carbine stock, that looks about right.

It's kind of an ill-defined term, and doesn't really mean that it was purchased whole. It could easily be a stripped lower + lpk + complete upper, or complete lower + complete upper. Either of those sidesteps the 10 day waiting period, and it's about the same price - you can get a lower+lpk with buffer tube and halfway-decent buttstock for something like $120, or you can buy a complete lower for about that same price.

Assuming you just buy a stripped lower and not an 80% lower, assembling requires minimal tooling - a couple roll pin punches, a hammer, some pliers, a hex wrench, and maybe another wrench. A vise grip makes it easier but isn't strictly speaking required. Takes like an hour or two even if you have no idea wtf you're doing.

That said, I agree it's probably more likely they bought it whole, or bought a lower+upper and just slapped it together (which takes 5 seconds and zero tools).
