mossberg 500a question

[frexe]

I recently purchased a mossberg 500a, dissassembled it to clean, and learn more about the gun following the manual, and the Life Liberty video. However, Im having some trouble attaching the barrel back on. There is a small gap at the point where the barrel fits onto the magazine I hand tightened the screw cap but the gap remains. Is there suppose to be a gap? Or did I do something wrong.

A small gap is not a problem, and is normal. If you look inside the receiver and the rear of the barrel extension is tight with the recess on the top of the receiver - that tells you the barrel is seated.

There is supposed to be a small gap there. As mnrivrat stated, look inside at the barrel extension/receiver joint; if that is snug, you are set.

DO NOT TIGHTEN THAT SCREW WITH "VISE-GRIPS", PLIERS, ETC. You WILL wreck stuff doing that.

Never mind HOW I know, I just know.

Mossberg has the manuals for the current firearms on their website for download if you need it.

www.Mossberg.com

look under the Customer Service link for "manuals"

I did a copy-n-paste out of the manual, but I couldn't get the pic to copy below...

500®, 505™ and 535™ Models Slide the barrel into the receiver and tighten the takedown screw, finger tight only. DO NOT use pliers or a wrench to tighten the takedown screw. A little space between the magazine tube and the takedown mount is normal.

WARNING(all models): Check to be certain that the barrel is fully seated into the receiver by looking through the ejection port. The barrel extension must rest firmly against the corresponding cut in the top of the receiver as shown in Figure 4.

Yeah, I read the owners manual several times it did say dont use anything but ur fingers to tighten the cap. But never said anything about there being a gap. Thanks guys
