Sorry, I didn't mean to slam the OP.

I just meant that I'm not as uncompromising as Iraq Guns, and I didn't think the OP was, either.

To me, buying an upper with a Colt barrel and then replacing the upper receiver because the hole for the ejection port cover pin is crooked is roughly analogous to buying used car with a nice Hemi, finding out that the trunk release doesn't work, and then doing an engine swap to rectify the problem.

Obviously I do sometimes "half-ass" things (let me say, too, that I've never seen someone use "half-ass" as a verb before this thread).
