Pistol Build ideas?

[EastTexasAg]

So folks, total new guy here. I?ve never built an AR more than buying a complete upper and building a lower myself. That being said, I?ve decided I want to build a 10.5-12? Grendel pistol. I?m tired of toting my 24? monster anywhere but the bench. Lol. Anybody have any ideas or advice on the project? All I know is that it?ll end up with a thermal/NV just to knock down swine at a seconds notice day or night at this point.

Precision firearms is running a sale on short barrels. Call him up.

I used a complete aero precision kit with my 12.75” group barrel and have been very satisfied with it.

I think you'll really like a 6.5 Gr pistol!! I used a Ballistic Advantage 12.5" barrel. Accuracy is good; ~1.25" using American Gunner & other Hornady factory ammo. Haven't had the time to try any reloads in it yet, but hope to soon. I had to drill the gas port out to get it to run correctly. It came with a .055" gas port per BA, they said they assumed everyone would use a suppressor on that 12.5" barrel, I don't. I measured it as .050". After I drilled it to .073" it runs like a champ. Gamma 6.5 VG6. Vortex 2-7x32. It's on a 80% lower I finished, Geissele S3G trigger with a Law folder and a Tailhook brace. It's my favorite AR right now. The lower used to have a 10.5" 5.56 upper on it, I still have that upper, but haven't used it in quite a while.

My latest G has a 11.5" AA barrel and Aero builder kit with Strike Viper PDW brace... Works well

Built 1 with a 12in PSA barrel. Just killed a deer at 186yds with it.

Man, I wish I had the equipment to finish 80%ers myself. Just don’t have the tools/equipment yet. I’m about to pick up some 80% to sit on until I do though.

My 12" using the group buy barrel. I'm going to change the scope though. Gibbz side charge upper. SBA3 brace.

[BCHunter]

So building an upper is simple just requires some tools, a vise, torque wrench. And reaction rod or bev block to hold the upper.
I switched out my vg6 brake for a linear comp, unless you wear hearing protection when you use it, the bark is fierce.

[EastTexasAg]

Oh, the upper I can sort out. It’s the lower. I don’t have a press or anything. I’ll end up going linear, i can’t stand wearing ears. Lol

I’d like to see that. What’s your OAL on that one? I’m flip flopping between barrel lengths.

[1075 tech]

Just for reference, my 12" with the SBA3 collapsed is 26.5" OAL.

[BCHunter]

I'm confused on what you need a press for on the lower?
Roll pin starter, and punch set is all ive ever needed.

I think he's talking about tools needed to finish a 80% lower.

The LAW folder adds some length. Folded is 23.5", open/unfolded is 32". I like the LAW folder, I put it in a tennis racket case/bag and put it in the floor of my truck.
