kingsey 0 Posted August 13, 2014 Hello guys new member here. I've been kicking the idea around of building my first ar. I originally wanted a sig 556 but it seems very difficult to find someone would can pin that type of stock in nj, so I've moved on. I do like the idea and cleanliness of a piston system. Anyone have a 516? Worth the money? Quote Share this post Link to post Share on other sites
Blake 50 Posted August 13, 2014 Monmouth arms (remixer on njgf) has one in stock nj compliant for a good price. Pm him. That being said you can easily build an ar to your specs for the same or less than buying factory. Just dont expect the resale value on a built rifle to be the same as a factory one.

High Exposure 5,635 Posted August 13, 2014 The Sig 550/556 series are unique and reliable guns. They are not traditional ARs and are probably closer to AKs in how they function (I have a buddy that refers to them as the nicest AKs he has ever seen). As such, the below is in reference to Sig 516 and other piston AR variants only. Quality piston ARs are ok but not necessary by any means. I actually prefer a traditional DI gun to a piston gun. You are paying a premium for a piston system that is allegedly offering a perceived advantage that you will never see the benefit of IMO. But you will pay extra for the rifle, have a hard time sourcing parts for preventative maintenance and they will be more expensive when you do find them. This is assuming you are starting with a quality piston system (LWRCI or HK). I would rather spend the extra money on ammo and training from a reputable instructor than a piston AR. That being said, I would like a Sig 556 but I would pass on a Sig 516. Quote Share this post Link to post Share on other sites
remixer 1,645 Posted August 13, 2014 The SIg556 is nice but pricey. I would be happy to get you one but for few hundred less you can get this Sig m400 Swat which uses standard Gas system. Quote Share this post Link to post Share on other sites
locochinoloco 0 Posted August 13, 2014 I have a SIG516, it's a nice rifle. There are nice little features that makes it different besides the piston. Cons: The piston system is a bit heavier than DI Wolf ammo doesn't cycle properly There are VERY few aftermarket rails to choose from However, If I knew then, what I know now, I would build my own AR... OR buy the M400 from Steve and slowly upgrade.

Rob0115 1,105 Posted August 13, 2014 Have one and I think it's the best deal in piston rifles. Quote Share this post Link to post Share on other sites
GJC88 0 Posted August 14, 2014 I too have one and I love it (granted it is my first AR) but I didn't have any of the problems I read about (not cycling. 223, bolt not locking back on last shot). It is definitely heavy compared to other DI guns and the basic irons aren't great but for me the rifle runs great and shoots well. Trigger isn't too bad either and it really is practically clean even after a few hundred rounds. Quote Share this post Link to post Share on other sites
tuktuk 16 Posted August 15, 2014 Sig 516 is a great rifle. i was about to buy one but came across a really good deal and got a PWS upper instead for my piston AR type. I have both DI and piston rifles. Honestly no difference just preference. If u re planning to take 1 -2 classes a year and go plinking , standard basic middle of the road AR type is all u need brother. like HE said spent the cash on the ammo .....
