What are your opinions? Is the lower made of plastic/polymer? I have a friend who might be getting one and want to give some insight on the quality. Thanks.

Do you by chance mean VULCAN? I was not aware Vector made an AR15.

Yes, I meant Vulcan. What are your opinions?

vulcan = hesse.  rumor has it they changed names simply to escape their reputation for sub-par quality.  new name, same old shit.  and when i say shit, i mean shit.

run away and never look back.

I just read a few other posts on other forums I found using Google and found the samething. What I also find funny is that Vulcan's website isn't working properly. It may be due to maintenance or there must be quite a few special forces members trying to get a superior rifle! LOL!

Vulcan=crap.You may get a decent product from them here and there but it's rare.They also have horrible customer service.

Vulcan, the God of Fire and steel, Guns of the special forces!

My Hesse/Vulcan AR plastic receiver (stamped HAR-15) developed serious slop in the hole for the buffer retaining pin. To the point that after a single shot, the recoiling buffer in the tube would propel the retainer into the inner workings of the action, jamming it up.

I finally moved the functional upper to a Stag lower I put together. I put a CZ V22 dedicated .22LR upper on the Hesse/Vulcan plastic receiver to avoid having to junk it all together. The V22 doesn't really need the buffer.... I may someday drill out the hole and sleeve it with a metal sleeve to hold the buffer retainer properly. I hate not being able to put a regular upper on it.
