AR Pistol build- input appreciated

[YFallston]

Another thought... If I plan to use a Sig Sb15 brace do I need a specific buffer tube? Will using a buffer tube with a castle but interfere with the brace?

No idea why that face popped up on my post???

It should work with standard pistol buffer tubes, but some companies are making brace specific ones which prevent it from sliding all the way down. Phase 5 and KAK industries are the two that come to mind off the top of my head, the KAK has adjustable spacers so you can set it up as comfortably as you'd like.

As for the smiley on your post, you must have accidentally clicked the "Post Icon" when you went to hit "Submit Reply."

Is it better to buy a pistol buffer tube with a castle but? Didn't know there was any that didn't have one.thanks agin guys this is the kind of help I wanted.

Get whichever one suits your fancy. If it doesn't have a castle nut, just toss a lil loctite (i have a bottle of rocksett handy, so that's what I used) on the threads and leave it alone till the set time has passed.

45, but I don't think they make the parts for an AR lower.

To expand on this, KAK has a new-ish "Super SIG" buffer tube made for the SB-15. Combined with the spacers you can choose a similar LOP to your carbine setup.

I just ordered a set last night with a 20% off coupon found on facebook:

+1 on KAK. I run this tube on mine and I love it. Without spacers, it holds the brace at one position out

Just my personal $.02, but I'd go with piston as well on shorter builds, but not necessarily for reliability/cycling purposes - if you ever want to add a suppressor, the piston will be worth its weight in gold.

I'd also go no less than a 12 inch barrel, depending on how much velocity/effective range you want it to have.

Phase 5 makes a buffer tube(Hex-2) specifically designed for the Sig brace and includes a castle nut and it does not interfere with the brace.
I have one on my 7.5" pistol and it's perfect for the Sig brace.

Here is the link to it;

I ordered the Spike's kit. I didn't necessarily want the "shelf" on the KAK or Phase 5. That way I can slide the brace up further should I decide to.

I bought the Phase 5 for the opposite reason, I needed the brace to go back farther as it was not comfortable and not far enough back with the PSA buffer tube.

If you guys are putting stocks on your pistols, I sure hope you've got a valid tax stamp on hand.

If you're referring incorrectly to the sig pistol brace, then you may not want to use the word "stock" as that implies you're discussing rifles.

You are absolutely correct, I used the incorrect terminology referring to the brace and that's not good.

Thanks for the heads up!

I am waiting on my YHM hand guard to be delivered tomorrow and my 8.5" 9mm AR pistol will be done. I did however order a Sigtac brace to complete it entirely. I quickly fell in love with 9mm AR15 rifles. I will post pictures in this thread when it's done.

I put it together with mostly stock parts. I will be changing out some parts like an Ambi Safety.

I second the phase 5 hex buffer tube kit. Fits perfectly with the sig brace for me.

That upper picture shown is gorgeous.

Tagging this thread for future reference the 7 day wait has commenced on the pistol lower I ordered.
