No. Just lube it, push the pins in, check for proper function, shoot and repeat.

Check head space when installing a new bolt or barrel.

A cautious person would check head space with a no/go gauge set....most including myself say don't worry about it and shoot the thing

If it was a complete upper, PSA already did that.

It couldn't possibly hurt to check if you have the gauges however

Gauges are only $80, why risk it? I don't want to be the guy that didn't check the headspace and blows apart a $500+ rifle, but that's just me. |

You can find them cheaper, but here's the ones that I bought for 5.56 NATO http://www.ebay.com/itm/NEW-FORSTER-HEADSPACE-GAGE-556-NATO-MINIMUM-MAXIMUM-MFG-HG556NATOMIN-MAX-/201397276854?hash=item2ee43690b6 http://www.forsterproducts.com/store.asp?pid=27204 |

If the upper comes with a bcg, then they checked it. If you bought the bcg separately, I would get your local gunsmith to check it or buy the gages.

PSA uppers whether they come with or with out a BCG are test fired so if even if you use your own bolt and ours in with in specs it should head space properly. I've used many PSA uppers now for myself and building for freinds and have had no problems. The lower is not important unless it's not made correctly then you may have problems with upper and lower fitment and take down pin alignment. So far I've not heard of any PSA on PSA problems.

I don't check headspace with AR's (either my own builds or complete uppers). But I guess I just live on the edge

The "check" or "or not to check" debate comes up often.
There seems to be an even split as to those who do or do not check headspace. While there could be more reasons why some do not check headspace- I think these are the main ones. -They do not believe it is important as long as the parts they are using are "in spec." -Somebody they trust told them that they do not need to check it -They do not know how to check it or they have not invested in the proper tooling to do so I check every upper I build and there are reasons why manufacturers check it- to cover their butts and it is just the right thing to do IMHO |

It's cheap insurance to check it and only takes a small amount of time.
That said...I've yet to have an AR or any of the M4's I've worked on fail to head space properly. I still have checked every single one though. |
