Brownells Buffer-less AR Pistol Upper

[WillBrink]

I had no idea Brownells made their own stuff, much less something unique like that, Buffer-less AR Pistol Upper gas piston design. Any see such a thing in the wild yet?

Made by PWS. I've got a gen 1. I love it. Its make favorite upper to suppress.

Good to know, interesting.

So where does the BRN -gen 2 fall in the short stroke gas system model world? Isn’t the 180 system an early progenitor of the G36 type? I’m just throwing crap out there so that someone can dazzle us.

300BO would be interesting.

Above my pay grade but the 10" 300BO is the one I'd be interested in myself.

Yes, the G36 could be said to be based on the AR18. It works very similarly on the inside and uses action and gas parts of similar design.

I’d say every rifle I can think of from HK is derivative. Edit: the G11 was completely novel and rather clever. It derives almost nothing from anywhere.

How does that compare to the HK416?

“The one that’s mostly AR15, and partly AR18 edit: G36?

The G36 is heavily inspired by the AR18, with most of the big changes being external.”

-Eugene Stoner, probably

I didn't know the G36 was based on the AR18, but "The HK416 uses a HK-proprietary short-stroke gas piston system that derives from the HK G36, forgoing the direct gas-impingement system..."

Shit, you’re right. The AR-18 borrows from the Tokarev short-stroke piston, and the short-stroke piston in the G36 is a bit different, and yes, the 416 uses that style. The regulation is done differently, and I’m not sure of any preceding designs that use that little nub blocking the forward gas vent.

However, the BCG of the G36 is very clearly borrowed from the AR18, much like almost everything but the gas piston of the 416 is borrowed from the AR15.
