Advice on first Grendel build.

[Nutt51]

I just joined fellas, this is my first forum post.
I am intrigued by the 6.5G. I must have one.
My quandary,
I have a Colt Match Target HBAR MT6700.
Don't know if Colt uses a heavy walled rigid upper
receiver on the HBAR or not, so my question is
would it be worth the trouble to convert it to the 6.5G.
What parts would be needed other than a new barrel,
bolt, FF handguard, gas block, and new mags?. or,
would it be simpler to just buy a whole new upper from
Bill Alexander, slap it on and be done with it.
I would be using this rifle for long range targets and
perhaps some hunting, so I was thinking a 20" or 24"
free floated barrel and handguard, with a Leupold MK 4 on top.
I would appreciate any advice or recommendations.
Sorry for the long first post. Many thanks.

I would keep your colt how it is and buy or build a complete 6.5 upper. The 6.5 cost more to shoot and in those times you find yourself shooting large amounts you are going to like the 223.

If you decide to build you are going to need a barrel wrench and action block if you don't already have those tools.

Thanks for the reply GrantMan.

I have another AR that is set up for fighting, so I have one to burn ammo with.
I was hoping to turn the Colt into a more accurate long range rifle on the AR platform.
I thought perhaps I could convert it to the Grendel with a minor number of parts
by putting in a top quality barrel, bolt, FF handguard, gas block, and Grendel mags.
I have access to the tools for the change, but it may be just as easy to buy
an AA upper and just switch them out. Many thanks.
