Hi all. I have been thinking about an AR-15 type sporting rifle and was looking at some of the Sig Sauer models. Does anyone have any thoughts or recommendations on which model is a good intro to the platform? I have access to an outdoor shooting range and would like some recommendations or thoughts.
Thanks
S&W Sport is inexpensive but not cheap. I love mine.
My first one I went with a Ruger 5.56, great rifle. The rest I built,
What are you looking for in an AR-15. That is what is important. You have to get what is right for you. I hope you get what you want.
OK maybe I’m different, go big, don’t go cheap. Get a high quality rifle from a quality builder. 5-6-8 years from now you’ll be glad you did.
I’m looking at an HK or a Daniel Defense right now.
sigsauer.com Check out the nice selections of the Cross Rifles, and Spears 
ahhh… ummm… pink?
Like @Ronald150 said, go to sigsauer.com.
I would recommend using the drop-down menu and select FIREARMS/All MODELS. Look at the filter(s) available. Skip past the Model selection and look at the Caliber selections. As you can see, there are a lot of selections there. The “most” common calibers chosen for AR-15 are 5.56 NATO, 9mm Luger, and 300BLK probably in that order. 5.56 is usually chosen because that’s the original caliber it was designed for – it can be used for general plinking, self-defense, or small game hunting. Some pick 9mm because ammo is more economical, about half the price of 5.56 and you might already have 9mm ammo for your pistol. 300BLK is usually chosen for self-defense, especially when combined with subsonic ammo and a suppressor. 300BLK ammo can become pricey for general plinking. 300BLK can also be used for small to medium game hunting at 100 to 200 yard range; basically 300BLK is a lower powered 308. Unless I overlooked a caliber, all the others are going to be larger AR-10 platforms.
The next drop-down will be Operating System. Gas Piston will be the most expensive, yet cleanest operating. “Most” AR-15s are Direct Impingement.
Back to your original question: just like pistols, all AR-15s are the same manual of arms, so you will get the same operational experience with any of them. From a higher level view all AR-15s will fall into 3 categories: Pistol, Short Barrel Rifle, Rifle. Their classification is based on current political swings, but only the SBR requires a tax stamp. There are a plethora of choices, but you can’t go wrong with Sig. However, as you can see from responses, Sig has a lot of stiff competition. Ultimately you can dip your toes in and go economical to see if you like it. Conversely, you can chose to pay once and cry once 
Edit: looking thru Sig’s products these are 2 you might want to consider: https://www.sigsauer.com/m400-xseries-sdi.html or https://www.sigsauer.com/m400-tread.html
Greetings, Bart7
There’s another caliber and two chamber options not yet mentioned to consider. The caliber that I am referring to is the .223 Remington, it’s a common chamber and ammo caliber.
When choosing, there are a couple of things to consider. A rifle chambered in .223 Remington can only fire .223 Remington ammo. On the other hand, you can use both 5.56 NATO and .223 Remington in a rifle chambered in 5.56 NATO.
There’s another option though, which is what I went with, the .223 Wylde. This takes the best of the 5.56 NATO and .223 Remington chambers resulting in the ability to use either 5.56 NATO or .223 Remington with greater accuracy and reliability. These two benefits allow the rifle to be more versatile than either a .223 Rem or 5.56 NATO.
To clarify, the .223 Wylde refers to the chamber, not the ammo (there’s no such thing as .223 Wylde cartridge).
Sig Sauer does offer an AR-15 with a .223 Wylde chamber, though I am not sure that the cost is something that I would consider a “good intro” into the AR-15 world. Their offering is the M400 DH3. There are more economical options on the market if you’re not limiting your manufacturer to Sig Sauer.
Good call on the 223 Wylde. That’s what I have as well. I just didn’t see any 223 Wylde on Sig’s current standard production offerings.
The specifications don’t detail it properly, but if you click on the “Details” tab it does.
This onion has a lot of layers. Your next question after you chose which AR is how do you want to aim it?
You could get iron sights or a Red (or Green) Dot Sight (RDS) for under $100. Or you could get a Low Power Variable Optic (LPVO) for hundreds to thousands of dollars. Or you could spend thousands of dollars on an optic if you can afford it.
This is an exceptional deal on an LPVO: https://palmettostatearmory.com/vortex-strike-eagle-1-8x24-gen-2-riflescope-w-ar-bdc3-reticle-vortex-sport-cantilever30mm-ring-mount-2-offset.html
Use code “Strike” and it is currently $260 for an $800 package
Edit: It is my understanding that if you add a magnified sight on an AR pistol, it becomes an SBR. So if you go the AR pistol route, iron sights and/or a RDS without a magnifier will keep you out of the tax stamp arena.
I can’t speak for everyone, but everyone I know who wanted/bought an AR went through this same exercise. I made a spreadsheet which made it a lot easier. Be clear on your requirements up front…then modify them as you gain more knowledge. Rate your top choices. Let us know what you end up with. PSA makes a lot of good stuff too.
I probably do not have near the quantity of firearms that some do. But I prize quality over quantity. I have multiple Daniel Defense AR-15 platforms.
I had been thinking of an AR platform, until I learned that bull pups existed!
At first I was thinking about the FN S2000… looks like a phaser rifle from Star Trek, the shells eject from the front of the gun, just nifty!
But when I handled one, I was less than impressed with the internals, access to clear jams, and the complexity of tear down.
……………
Of course there is also the Steyr AUG too,…
…………….
I settled on my IWI Tavor (and later added the black 7.62 NATO version)
Still super happy with my purchase (es) and have no desire to own a typical AR platform beyond my M&P 15-22! 
I have nothing high quality…so they match me. 
I’m not likely to own anything I’ll have heartbreak over if it is stolen. They’re just tools and useful for a hobby. They have to work, and I’d rather have a few Walther Creeds around the house than one PPQ I can’t get to. Neither is going to shoot better inside of any single room. If bad guys are further away than that, I try to escape. I’m worth only slightly more than my cheap firearms.
I’m still saving my pennies for a Springfield Hellion. (@Don102, has been a slacker in getting me my 10% for the big guy),
I know I left a lot of bullpups out of my post, those were the three I was able to hold in my hands and compare side by side by side (minus actual live fire 
)
I want an SBR version of the FN P90! (The 16” barrel looks weird)
………………
Cool
Weird
Edit, and yes, I’ve handled, (not shot) the P90 16” version, I like the way it feels and functions!
Just the tax stamp, and NFA crap for the SBR.
