SR-556 is a Piston driven AR, so if one of those show up you'll be able to see one. I think LWRC, Ruger, LMT, POF, and Para-Ordnance all have Piston driven ARs. I'm sure I missed a company, but those are the ones I know of

Ruger SR556 would qualify, as would LWRCi, POF, Addax or any of the retrofit kits out there.
ETA - OneBadV8 was quicker on the trigger... but the Para gun is not a true piston system.

The Para TTR (Tactical Target Rifle) is a repackaging of the Z-M Weapons LR-300 design that has been around for many years. Para calls the operation a "delayed impingement gas system" (DIGS), which Wikipedia describes thusly:
The LR 300 however uses an adapted version of the AR-15's standard direct impingement gas operating system which removes the need for a receiver extension.
The gas key is extended beyond its normal length to form an operation rod, such as an M14 or AK47, extending into the top of the forward handguard. The gas key contains the return spring which is fixed between the front of the receiver and the collar at the front of the gas key. The gas tube runs backwards from the gas block in the front sight base and enters the gas key. In this way when the firearm fires at least some of the combustion gases from inside the gas tube are vented into the handguard area rather than the receiver. This means the standard buffer assembly is not required at the rear of the weapon, allowing a folding stock to be fitted to reduce the overall length of the weapon, and reduces gas fouling in the receiver.

That would be good in the winter time. Should warm your hands a little faster...
That would really be interesting to see. I'll try to make it out to crash the party, but who knows.

Count me in. Looking forward to seeing all the cool setups!
great idea
Count in one more noob, I will bring my colt hbar 5.56. It is a tack driver.
It's nothing special so it will stay in the car until requested. see profile for pics. I am looking forward to an educational event.
should someone put this event on the "calender" of the website.
I'm one that would like to see the tools.

No Ammo In CCWs?
Was this question answered explicitly? I didn't see one, but I might've just missed it. And I'd rather be the fool who asks it again online rather than the fool who brings in a loaded CCW when that was clearly not supposed to happen!
It looks like I'll be coming alone. Dad isn't interested and my brother is going to Florida that week! Nevertheless, I'm looking forward to learning about the weapon.

I am planning on attending weather permitting. I only have one AR, a lightly moded CMMG. I am trying to get a couple of my buddies who are interested to attend also. Very interested in learning about building the next one I get.
Given that all it takes is a stiff breeze to make some AR bolts go forward, it might be a good idea to use chamber flags. They'll make it easy to see for sure that a yellow or orange piece of plastic is stuck in the chamber, so no round can be in there.

This sounds great! I've got one I've built that is basic, but cool, and my R15 for the hunter table. It is a great hog or coyote blaster. Hopefully, I'll have my new 6.8 upper, and can put together my ultimate hog blaster before the event.
