[MrCaptainNObeard]

every upper i have looket at say :no bolt, "bolt carrier or charging handle included" do they sell uppers that include these parts?

[SoCalPreppers]

@MrCaptainNObeard yes.. what you would search for is a "complete" upper... that will come with everthing and most likely the barrel as well.

[MrCaptainNObeard]

@SoCalPreppers thanks man,as you can tell im new to this.

[SoCalPreppers]

@MrCaptainNObeard no worries bud, we all have to start some where!

[notanotherCoDfan]

will any upper work with any lower? like a DPMS upper and a bushmaster lower??? i need help :(

[SoCalPreppers]

@notanotherCoDfan for sure. some will mate better, with little or no movement between the two , but for the most part, all mill spec parts will marry other mil spec parts very well.

@notanotherCoDfan No. Colt had a special version called the SP1. It used a larger front pin in order to prevent the colt upper from being used on other lower receivers.

It's rare to find one but they are out there. If your buying used, make sure the holes are the same size and you'll have no problems.

Almost didn't catch the 'That's what she said' joke at 11:11

That front sight/gas block is pretty slick, I might add that to my wish list for my future AR build.
