AR seized up, any guesses?

It sounds like your buddy needs to be treated like Private Snuffy and given the correct training on how to maintain his rifle. Whether you go into drill sergeant mode or not is up to you.

Is it possible he was shooting any old steel cased lacquered rounds? There was a big problem with the lacquer melting in the chamber as the gun heats up due to rapid fire. This was well known to cause this type of jam. The perp was old Wolf and Brown Bear rounds produced in Russia.

Nope, recent production S&B brass cases- although its perfectly possible that the previous owner left some lacquer or other funk in the chamber.

Lesson learned, he bought a good, AR-specific cleaning kit. I did give him some better magazines, though. The ones that came with the gun were SCARY.

The fact that it is a Radical Firearms brand and it runs is kind of scary. I bet it is minute of soda can at 50 yards if he is lucky.

I know, right......

The hard parts seemed ok, but all the polymer bits were pretty crappy, especially the sights and pistol grip. If it doesn't act up again going forward, I suggested he treat it to some Magpul upgrades.

Stand the rifle up. And bang in on a table top on the but end of the stock. While pulling the charging handle. It may take a few times. But it will un-jam.

This is SOP at my range, the ROs taught me, always works. Don't do it in the house, and point it at blue sky.

Yes always do it out out doors pointed up. I put these on my AR stocks to protect the plastic. They are on amazon. Since the update to the site. Amazon links don't work.

For all the hate ive read on Radicals both of mine ran like tops, and even after having the grendel barrel turned down it still shot moa or better.
Barrels looked like cheese graters and that's without a bore scope lol.

My 10.5" Radical upper ran good too. It just would not shoot worth a darn. It patterned like a 12 gauge buckshot load at 50 yards.

There is actually a tool to move the bolt. It inserts through the mag well.

Or you can put the charging handle against the table and give it a good push.

Lisle automotive tool. part # 35260 - plastic fastener remover. You can buy them at OReillys for 14-15 dollars. It comes with a sliding rubber ball on the shaft to be nonmarring and give you a good fulcrum point on the front of the mag well. The forks fit right in front of the bolt carrier and will dislodge these types of stuck rounds in AR's without mortering them and possibly damaging the buffer tube or lower receiver cracking. Keep one in my AR toolbox. Have used it many times.

Sometimes being a simple redneck motorhead comes in handy!
