Re: 9mm SBR Thread
Thanks for all the great info guys! I got a Thor hammer glock lower from runner runner guns in TX and a 4.5" barrel from joebobs. I efiled a form 1 for the lower yesterday. Pretty excited about the build. Thinking about a matrix side charger upper receiver and a nfa bolt carrier. Im still deciding if I want a carbine or mid length rail.
Re: 9mm SBR Thread
You guys that have used a side charger upper what are you using as vice blocks to clamp the upper to install the barrel?

I used a piece of carpet and a vice to put the barrel on.
Re: 9mm SBR Thread
I saw you used one, just wondered how you installed the barrel. I have upper vice blocked and barrel blocks but with a 4" barrel the barrel blocks won't work and the upper blocks won't work with the side charger. Thanks for the info, I'm considering the matrix upper. How do you like it, any problems?golfindia wrote:2nd post on page 3 is a matrix upper.farm use wrote:You guys that have used a side charger upper what are you using as vice blocks to clamp the upper to install the barrel?

Re: 9mm SBR Thread
It works great, never had an problems with it. The side charger is much nicer to use, if they weren't so expensive I'd get more.
If you use a regular lower, you could use a mag block type holder in a vice. My lower is a dedicated 9mm. so carpet or a barrel vice were my only options. There's no brass deflector or forward assist on the upper, so a vice worked fine.

Re: 9mm SBR Thread
Thanks! No iv got a dedicated 9mm lower also. What bolt are you using in it? I was wanting to use the new frontier armory bolt carrier.
Re: 9mm SBR Thread
Bolt was from PSA, on sale.

Re: 9mm SBR Thread
farm use,
Instead of a upper block holder or barrel vise consider a brownell's barrel ext. torque tool, or a similar geissele product. No worry about twisting an upper or needing a barrel vise.

No lugs on a 9mm barrel extension.....DeadRaibead wrote:farm use,

Re: 9mm SBR Thread
golfindia,
Thank you for educating me. I have never had in hand a 9mm ar, and did not know about the different extension. Been toying with the idea of building one, and I am glad to have that information. Rules out a side charge for me.
