Hey guys, I am working on my first build and I am about 75% done. As of right now I have everything except for the barrel and all necessary parts to attach it. Now, with there not being a barrel attached, will it cause any harm to the BCG or upper if pull back the charging handle and releasing the BCG. I have not done it yet, just seeing if it would hurt any. Probably a dumb question, but just wanted to check. Thanks again

Thanks for the speedy response and I definitely will not be doing that. Have a side question as well if you don't mind. I plan on getting a barrel from American Spirit Arms (no one else seems to have them in stock, plus they are local) and I was a little concerned about headspacing. The average response from people is that if you are buying mil spec parts, don't even worry about it. I just want to make sure that I'm not going to run into issues, so I was wondering if it is something you should absolutely check, or is it not worth the time. Thanks again guys

I've actually DONE this a couple of times. What happens is the full force of the spring gets taken up in the buffer hitting the buffer retaining pin. Even three or four times will leave a visible mark on the face of your buffer. I'm not sure how this compares the beating those same parts take when actually firing. I'm not sure what stops the BCG. Either it's the gas key hitting the front of the upper, or the charging handle hitting its stop. Again, while this is certainly more force in those places than during real use, I can't tell you how MUCH more. The difference would be that in real firing some of that load would be taken up by the bolt's interaction with the barrel extension as it locks. My take on it is that a couple times shouldn't be too bad, but don't make a habit of it. |

Quoted:
i can imagine no good coming from doing that. i definitely wouldnt. thats a stout spring and a heavy bcg , lotsa inertia with nothing to stop it. except parts tha arent supposed to. dont do it. +1 - No point sending steel slamming into aluminum. Won't do your upper any good. |
