just looking for a good stating point, i'm sure I'll end up changing things down the road. always did when I had ar rifles
Careful, those are dangerous.does it come with one of the things that go up?
Palmetto has great deals.I have been looking at ar pistols lately and have decided I want one. looking at one in 5.56. who has one? looking for pro's and con's what should I be looking for if I end up finding a used one?
I think everyone is in agreement that military ammo is a no go in an sbr, other than plinking and saving money. I myself will be stocking up on fusion msr 62.
This.^^^
As with anything, the right ammo is necessary. Just like you wouldn’t use a ball round for a deer, you wouldn’t use a low velocity ball round that relies on fragmentation for home defense in a short barrel. A hollow point that goes over 2500 FPS is in order.
Yes, I wouldn't want to be shot with m193 from an sbr, but fact is coming from my 10.5" barrel it's not going to perform reliably and fragment as intended. 2600 fps is minimum speed for fragmentation (2700 more reliable) and I only get ballpark 2600 at the muzzle. There certainly are better loads for short barrels.I disagree. If we're talking self defence against humans any 556 load will be effective at just about any length barrel. Even ball. You could argue how effective one loading to another is but to say that certain rounds are useless for anything other than plinking is ridiculous. If you think this then you may as well not carry handguns either. Mek is a target shooter(long range it sounds like). So any rifle that isn't full length with some type of magnifying optic is probably useless to him. That's what makes these debates about barrel length, velocities and sound even more of a waste of time considering that 99% of people here are shooting at MAYBE 100 yards max. There is no barrel length that won't be able to reach that. Loud? Well we wear earpro. That's my rant. Thanks.
ETA: get one of these, have fun and don't worry about what anyone else thinks

What is your idea of reliable? Or in other words what is your criteria for something to have "worked"? A 55gr ball round at even 2500 fps is going to do massive damage to a human. If the first shot isn't enough there is that thing called followup shots. Even though a 45ACP is barely fast enough to leave the muzzle of the barrel (according to @Marine Cpl) it's still effective. Alot of this is marketing.Yes, I wouldn't want to be shot with m193 from an sbr, but fact is coming from my 10.5" barrel it's not going to perform reliably and fragment as intended. 2600 fps is minimum speed for fragmentation (2700 more reliable) and I only get ballpark 2600 at the muzzle.

It only makes you dead. Not deader like it’s required nowadays according to some here. Those same people have no issues using a 55 gr at 150 yards when it slows down to that velocity of 2500 FPS. More so if it’s a 77 gr going at 2300 FPS at 150 yards.What is your idea of reliable? Or in other words what is your criteria for something to have "worked"?

You have a lower on your PP yet?so far this is the kit i'm looking at

I kinda want one but seems more pain than its worth.not yet, going to talk to my ffl tomorrow
Dead now is deader than dead in 5 minutes. In a self defense situation incapacitated now is better than dead in 5 minutes even if they eventually survive.It only makes you dead.

I had an 8" with a brake. The concussion and muzzle blast were incredible. I sold it soon after. What are you using for a muzzle device?Dead now is deader than dead in 5 minutes. In a self defense situation incapacitated now is better than dead in 5 minutes even if they eventually survive.
Just about anything can be effective. If someone is breaking into my house I'll grab my G26 before my 10/22, and the 10/22 before I grab a kitchen knife, and I'll take the knife before I'll engage bare handed, and I can disable or kill someone with any of those.
I have an AR pistol with a 7.5" barrel. I knew the ballistics of it were going to be crap before I made it. I wanted it anyway.
Still, it's better than the LCPII I carry all the time.
It would not be what I grab in a home defense situation, and I seldom hunt. But it is fun to shoot.
So, identify what purpose you intend to fulfill with the gun, then choose your parameters around that.
I understand your logic. Sure a .40 is better than a .22 lr. But the difference between one .223 bullet of the same weight going 2500 FPS compared to the same bullet going 3000 FPS at the same distance in the same spot on a chest is negligible. You can’t compare how far apart they are and say that it’s just the same distance apart as far as power goes as it would be with a 22 lr and a .223.Dead now is deader than dead in 5 minutes.

You are right of course, we have all these discussions about which caliber is best and so forth, and we are discussing the top few % of actual performance.I understand your logic. Sure a .40 is better than a .22 lr. But the difference between one .223 bullet of the same weight going 2500 FPS compared to the same bullet going 3000 FPS at the same distance in the same spot on a chest is negligible.

Proof of this comes from entry teams with 10.5 inch barrels making immediate kills at CQB distances. None are regretting their decisions and wishing they had 20 inch barrels to make their targets more dead because the bullet is going 500 FPS faster.
At a certain point, the bullets are just as deadly since both rounds fall between the same parameters that are required to kill you. Whether it’s a .55 gr or .62, the extra velocity of the .55 isn’t going to kill you faster than the slower .62 at 15 yards.
To be honest, whatever came on the PSA upper I got, since I had to fix the magazine to make it legal anyway I never gave it another thought.I had an 8" with a brake. The concussion and muzzle blast were incredible. I sold it soon after. What are you using for a muzzle device?
Welcome to the club! Looks like the same upper as mine. I really like the slant handguard they use. I also swapped out the trigger for a 3.5# timney.. only other thing I may change is a switch to a 12.5 barrel down the road since it's a 12" handguard anyways..receiver is on my permit now I wait for my build kit to arrive!!
Also from what I have read, it seems most of the psa pistol uppers are over gassed, so I also installed an h2 buffer. Hopefully I will get it out soon to test fire and zero. Seems I never have the time anymore.will do thanks for the tip. now I just have to impatiently wait for it to get here... looks like it shipped today
We will need pictures of final assembly Wednesday night.finally got my tracking, kit will be here wednesday
