Usually what happens is that the upper isn't fully closing. Mark the upper receiver's rear 'lug,' that the takedown pin goes through with lipstick or something, and close it as far as it will go. You will be able to see where the two pieces are contacting. Following the #1 rule of WECSOGing, 'file/grind on the least expensive part,' lightly file the contacting area(s), remark the parts with lipstick, and then try the fit. Repeat as needed.
Be patient and don't get carried away with the file, coz it shouldn't take a lot of metal removal to make things align. WECSOG - Wile E. Coyote School of Gunsmithing |

 i had a similar proble with a CMT upper. turned out the rear takedown post sat too low. ended up sending it back and getting a new one that fit like a charm. and yes, if you do any sort of metal removal, do it SPARINGLY! |

It's just barely off on the takedown pin. I'd hate to tie the gun up by sending it out. If it's an hour's worth of delicate filing, then I'd rather do that.

Get a hammer and tap it in.

On older lowers hole alignment was not uncommon. I used to remove the metal from the pin making the pin the shape of the hole instead of removing metal from the upper or lower. The last part of the pin for the thickness of the side of lower stayed full sized because it never goes into the upper lug.
I would make sure that it is hole alignment off and not the upper not being closed flat against the lower first. |
