Interesting thread over at GT about an AR15 problem.

I saw this thead over at GT and didn't see a duplicate here, so I decided to post a link.

This is just one of reasons first time builders should familiarize themselves with the AR system or have someone who is knowledgeable check their work.

From what I gather the weapon was assembled without a gas key on the carrier, leading to a KB.

That's why I read and re-read and read the all instructions again before I began assembly. I knew the operation of the rifle quite well before I even had one, if that part had been missing, alarms would have been going off big time.

Remember people, building this thing isn't like building a book case or stereo cabinet, you can't take a piece and flip it the right way after you fire a round and something blows up.

That's akin to leaving the cylinders out when you rebuild an engine. It might go bang a few times, but it's not going to be pretty.

I was kind of surprised he put that thing together and never checked the gas key, even though he didn't assemble the upper.

When I was putting mine together I studied the instructions for assembling the upper, even if I was only assembling the lower, and I made sure to check that the gas key was staked properly before final assembly.

I built my first AR, but I had already used M16s in ROTC, so I was fairly familiar with the platform. I also studied manuals and diagrams for weeks beforehand.

I ordered a kit from J&T and in 45 minutes had a rifle. It was like magic, sort of.

Good, informative post. I put my first one together with no AR experience. Here are the instructions I used. Unfortunately I don't see any upper instructions or any pictures of a bolt carrier with key.
