I had made a thread earlier about getting a EO-Tech scope for my M4. The problem is that I have a fixed handle on my upper. I had looked at attachments so I could mount the scope on the handle, or even on the forward grip, but it looked tacky. Someone suggested getting a new upper... but I really don't need all that, nor do I want to spend $400 to buy the exact same thing I already have, just with a flat top. I already have the barrel, the bolt, bolt carrier etc... all I really need is a stripped upper housing with the flat top.
Then I found this on Brownells.
It looks promising. It seems all I'd have to do is swap out my current barrel, bolt and bolt carrier, then pop it on my lower and I am all set. One thing I have learned about guns though, is if it seems easy, it probably isn't.
Is there anything in that above scenario that could go wrong before I commit and buy this stripped upper?
