This is my first post about my first AR. I am a very green gun owner. The other day I bought my first firearm, a Colt LE6920. Although I haven't shot it yet, I am very pleased with it.
I have educated myself to what I believe is a good knowledge base about the innards and workings of the rifle and in general about AR-15s.
I originally wanted to purchase a rifle with a mid-length gas system due to the reduced recoil and stress on the bolt. Due to the availability and eagerness to purchase, I opted for this Colt. Being a new AR owner, I'm not sure if it is a justifiable worry, but I asked the folks at the gun shop if they had any recommendations on how to reduce the stress on the bolt. They said I could put in a heavy buffer, so I picked one up. This evening I opened 'er up and noticed on the stock buffer that came in the rifle, there was an "H" imprinted on the flat side of it. The same "H" was one the new heavy buffer I purchased. Does the "H" symbolize that it is a heavy buffer or is this a regular stamp on all buffers?
If I do indeed have a heavy buffer in the rifle I purchased I will be returning the one I bought.
Also, can I get some feedback on my worry about stress to the bolt with a carbine gas system? Is this something I should be concerned about for a rifle that I would like to last me for a great deal of time?
Sorry for the noob questions. Looking forward to my new hobby :)
