I have a chance to purchase a Colt upper all I know so far is that it is a Hbar A2 upper complete. Ive built a couple rifles from stripped lowers and uppers but still consider myself a newbie to all of this. My question is should I buy the Colt which is a 16 inch not sure what turn is but thats not a big deal because bullet weight doesn't matter to me as I am just a bench rest shooter going out to have fun with friends or should I go with a Seekins Precision upper 16 inch adjustable gas block? Would the adjustable gas block benefit me in any way or is that a gimmick? What is a fair price for each of this the Seekins is 500 with bcg I was going to offer around 400/5-- for the Colt? Thanks for any help and also if someone could let me know about the customer service of Seekins that would be great I've seen threads about it from months ago but haven't seen any updates.

Does the barrel stamp look like this? 
Is there an "O" stamp near the chamber-end of the barrel?

colt 16" Hbars are usually 1/9 twist. I have one and it shoots great. The Hbar profile is not an issue for me but most people prefer a lighter profile. 69gr bullets gave me the best results. weight really isn't an issue but thanks for the reply any idea on a price? |

Is it harder to put an optic on the top of a carry handle like a nikon 3x9x40 or something similar? Quoted:

I have a 20" Hbar . It's a heavy weapon with an A2 leaded stock. It's a bench queen that shoots really nice. and very little recoil Is it harder to put an optic on the top of a carry handle like a nikon 3x9x40 or something similar? Not hard at all but a flat top receiver will make your life easier |

Yes it does say that on the barrel it does not have a large front lug its not been fired much and the price is 600 what do y'all think? |

All Colt barrels are marked with their twist rate.
A 1/9 limits you to 68/69 grain match bullets, it may stabilize 75's/77's but there is no guarantee. About half of all 1/9 fail to stabilize anything heavier than 69"s. As far as I know, true Colt uppers all have large pin receivers. Complete new rifles are selling under $1000 at this time. I'd buy new with a 1/7 twist barrel before buying anything used at a premium price. A flat top with a removable handle or BUIS is a much better option if you intend to mount a scope. A2 handles mount the scope way to high to achieve a good cheek weld. |

Going to just wait and buy a complete rifle and find a different upper for the complete lower i have laying around |
| Sounds like the OP question has been answered, but as an aside, I have a '93 Colt HBAR Comp with threaded pivot screw (requires a screw-driver to unthread, then normal operation to separate the upper from lower) and though I was worried about the large/small hole diameter question it turns out that it has a standard (small?) hole diameter that matched up to a modern day lower just perfectly. |
