Hey guys.
I've been hanging around this board for about 2 years, however never got around to signing-up/posting. Well, I'm having a bit of a problem and figured this was a good time to go ahead and get involved more personally on these forums.
I'm 20 years old and bought my first AR on my 18th bday. I've been shooting my whole life (learned to shoot before I learned to ride a bike), and was always interested in the AR15, however my father and my uncle are both very avid and proud Mini-14 owners, so my father never purchased an AR.
Anyway...
I bought an OlyArms PCR, 16"bbl A2. And I love it. However, I had an old school Aimpoint 1000 mounted on the carry handle, and I got annoyed of the crappy cheek weld. So I went ahead and bought a RRA flattop upper and collapsable stock and had it installed. This was just about a month ago. I was SO happy, I finally felt perfectly happy with my setup. I took it to the range and sighted in both the aimpoint and BUIS. Probably put 200 rounds through it that day. Well, I'm back at school now and I was sitting here playing with it when 2 or 3 times I couldn't pull the charging handle back all the way. It would stop about half-way back. I thought it was odd, but just dismissed it as being dirty, and well with turkey season around the corner I decided to give it a good scrubbing, hasn't been done in a while. Well, I finished cleaning the bolt and began just a wipe down of the upper receiver. I noticed a big ass scratch on its inside opposite of the ejection port about 2 mm up. It's a little bit smaller then a pinky finger nail. I NEVER noticed something like this on my old OlyArms upper. Now, is this something I may just have overlooked, but was there. What I mean is, is this regular wear and tear on an upper? Is this typical? Since I cleaned it, I haven't gotten the action to get stuck again, so maybe it's not what was causing the malfuntion. However, since I do not have another AR (yet) to compare it too and no longer have the old A2 upper, I have no idea if this is out of the ordinary.
I was going to post this in Troubleshooting. However, I don't know if this is a real problem. I'm curious if this has happened to anyone else before. If not, maybe I should take it back to the gunsmith I bought it from.
Oh yeah, ammo. Probably should mention what I was shooting. I shot a few boxes of Remington PMC and Winchester. Both 55gr.
Anyway, I'm looking forward to your comments.
Rob.
