516

Just got my 516 14.5 upper and I want to do a pinned and welded muzzle device. I will be using a binary trigger so I am looking for something to help reduce recoil and muzzle climb. Any advice would be greatly appreciated.

Anybody has experience using the FosTech Echo II trigger (or any good binary trigger brand) with the SIG 516? I looked up in FosTech's website and it says you need a full auto bolt carrier, with a note that "popular piston AR-15 brands work too". Anybody has ever used a binary trigger with the...

Hello All, New member here and excited to join the SIG community. Currently just own the P229RX Legion and love it. This is my first gun in a long while (owned a shotgun years back). I'm in the market for a rifle mainly for home defense and marksmanship skills. Having never owned a rifle of...

Anybody out there got any leads on a set of keymod handguards to replace the crazy heavy quadrails on a Gen 1 516? Appreciate the help.

I recently purchased a new 516 and it came with a magpul stock. I'd really like to find the factory Sig stock in FDE if anyone has one to sell. Thanks.. Newbie to the site, my 516 is the first AR platform rifle I've owned! :D

Sig recently came out with the PM400 PSB in the Spartan finish, which is cool on its own, but there are next to no accessories that would even come close to looking good with this finish. I propose Sig come out with an Emperor Scorpion version of the M400 or better yet, a 516 in that finish. I...

Hello I have searched the forum and could not find a fitting thread so forgive me if it already exists. I am looking to purchase a 516 ar rifle. The problem: My local gunshop has several in stock but they are different even though the specs/boxes say the same They all have the government...

anyone know of the feasibility of putting a 20" barrel on a 516?

Sorry if this has been discussed before. This is my first post. I've decided to convert my P516 into an SBR. (don't worry. I'll complete the Form 1) After adding a stock, I'd like to add a Sig silencer, when they finally ship. I guess the issue that I'm having is finding a new quad rail...

So my local gun shop guy talks so much to everyone about how all ARs are over gassed and so just swapping the buffer spring to a red extra power spring to help waste less energy in the gun and also provide a more gentle recoil. He was also saying swapping to a heavier buffer would probably help...

Hi everyone, i'm new on this forum and i hope my first post is not too stupid…;) I just purchased a new timney trigger for my rifle and disassembled the old trigger. But here's the point: I don't know how to get the safety pin out!!!! This drives me crazy, i just couldn't find anything on the...

HI Guys, I'm new here. Just bought a Sig P227 last November and love it (I'm a Colt 1911 man for the last 40 years, or so). I currently shoot an HK-91, which is a 308 rifle (7.62x51mm). It's a heavy gun and I am getting old(er). I am thinking about moving to a 5.56mm, and am very interested...

Hey everyone! First off my name is Nick, I am 16 years old. I am buying a 516, this will be my fith gun I own. My dad lets me have my guns in my closet (Has a dead bolt). This will be my first AR. Any tips or tricks I should consider? I am putting an EOTech XPS-2 and a Surfire M900V on it. Stay...

Hi everyone, I have purchased a Sig 516 Gen 2 and I am wondering if I can use my .22lr drop-in conversion bolt with this gas piston rifle? If so, what setting should I set the gas piston to? Thanks you.

I came across this forum and started reading some of the posts and they all sounded very intelligent and helpful. I have owned a couple different Sigs: 1911 scorpion, SP2022, mosquito and my latest Sig purchase is a 516 Patrol in FDE. Now, right out of the box I had an issue- it was dirty...

I might be the only one who wants one, but I recently purchased a new 516 and it came with the MOE stock. I have never been a fan of the MOE gear and would prefer the have the Sig crane stock that comes on the 716 and occasionally on some 516s. Does anybody know where I might be able to purchase...

New Guy here. Just picked up this 10" pistol and wondered what recommendations the community has for the flash hider replacement. I've not been to the range yet (picked it up last night) and know it's going to be loud. Thanks!

I was wondering if anyone has had any experience with the Daniel Defense Superior Suppression Device. Thinking about getting one for my 516. It is advertised as being a good flash suppressor and also able to control muzzle rise...

Hi everybody! My name is Ben, I'm new to the forum, new to Sig firearms, but not new to firearms in general. I live in Anchorage, Alaska, I'm a Veteran (Air Force), and am a general gun enthusiast. My fiancé and I try to get to the range a couple of times a month, and until this year, I was on a...
