Definitely worth the money.
The gas tube was slightly off center but it still shoots amazing and accurately.

Nice
Very nice. Fit well, shoots well, looks good, good price. Attached it to my lower, added BCG, CH and sights, stuck a mag in it and shot 100 or so rounds thru it. I really like the way it feels. I would recommend this to anyone for a first time build.

Anderson Mfg complete upper
Impressed with quality of fit and finish. As nice as complete upper two or three times the cost of this complete upper. Very impressed and happy with purchase. Plan on purchasing an Anderson Mfg lower to match this complete upper.

How do I know which upper I need for the gas tube?
Answer:
In relation to the item you have here i do not understand your question. Gas tube length is determined by the barrel all upper receives take the same tubes. Plus this item already has the gas tube installed. If you need additional assistance you can reach our product techs Monday thru Friday from 8am to 5pm central time at 1-800-421-8047 or by using our live chat feature.
Is this a low profile gas block?
Answer:
No, a low profile gas block does not typically have a rail on top. This is a 'Lower 1/3' gas block. The rail on the gas block is lower than the picatinny rail on the receiver, so you will need to use a taller front sight. Check out item # ARR-804 and ARR-276-082.
Can I put a standard front sight on this?
Answer:
No the gas block rail height is lower than the receiver rail on this upper, so you will want to put a lower 1/3rd front sight on it. I recommend item # 16-MT-750X or ARR-804.
Can I use my original bolt carrier?
Answer:
As long as it is for 5.56/223rem then yes you can.

Does this barrel have large or small pins?

Will it fit a Colt Sporter 6551 and can I use my colt BCG and charging handle with it?
Answer:
No it would not the 6551 has larger pivot pins and would need an adapter to work with standard Uppers.
What are the lengths of the two rails (front and rear)?
Answer:
The standard mil-spec flat top upper receiver has approximately 5" of rail space. The railed gas block is going to offer about 1-3/4" of rail space.

Is the gas block platform the same level as the rear platform to mount iron sights on this upper?
