SIG SG 552-2 with railed handguard, vertical foregrip, flashlight, and ACOG scope - 5.56x45mm

The top image looks like a 552, with the round bar charging handle, instead of a 553, which has a charging handle shaped like the one found on the 550/551. Dover500 19:38, 31 August 2011 (CDT)

Err, drat! I can't find any other images of a 553. D: - Mr. Wolf 23:38, 31 August 2011 (CDT)

The Easier way to tell is that the 552 has fixed iron sights and a removable rail (locks into a lug at the front of the reciever, and a bolt extends into the rear sight), whereas the 552 has a fixed rail that conceals folding sights. Oddly the above picture is the one used on the Swiss Arms website for the 553, so someone there dosen't know the difference either. --commando552 04:08, 1 September 2011 (CDT)

I did think the top one looked funny. :\ - Mr. Wolf 18:21, 3 September 2011 (CDT)

I can't believe it took me so long to notice, but neither of these weapons are actually the SG 553. One way to tell is that the 553 is also fitted with a Brugger & Thomet (same company that makes the rail systems I believe) flash hider that allows for quick mounting of a suppressor. The other much more obvious way to tell is that the gun has SG 552-2 written on the side. I didn't realise this version existed, but apparently it does, and as far as I can tell the SG 552-2 is a flat top version of the 552 with folding BUIS, sa appart from the bolt and flash hider (although that can be switched) is identical to the 553. For example, one can be seen in The Unit before the 553 was released in 2009 (also has the 552 type charging handle). Below is the only non airsoft picture I can find of a 553, which is the semi auto version. --commando552 12:32, 21 September 2011 (CDT)

SG552/556 uppers

Does anyone know if the uppers for, say, an SG552 and a SG556 pistol are interchangeable? I ask because was looking at the SG553 in Salt, and realised that the upper on it is identical to that of the SG556 SWAT pistol, which has a different front sight and flash hider to the SG553. Furthermore, the gun in Salt has a jet black upper, but the lower is the regualr SIG grey implying that it is built from two different guns. Below is a shot of the gun from the The Specialists Ltd's website, who supplied the guns for this film, and they list it as an SG552, which from the charging handle it definitely isn't. The uppers of the two guns look the same shape, but are there less obvious differences that would make swapping them a no go? Also, would I be correct to assume that a US company would have an easier time fitting a 556 upper to a 550 series lower rather than getting a 553? --commando552 18:01, 10 October 2011 (CDT)

SIG 750

Can anyone find any information on the SIG 750?? --Zackmann08 19:02, 10 February 2012 (CST)

First off, I think it should be "SIG SG 750", same as the other Swiss Arms rifles. I'm not sure if it is in production yet, but have found some figures. It has 3 barrel lengths:

• Standard barrel: 455mm (18in) barrel, total length 960mm, total weight 3.63kg without magazine
• Short barrel: 365mm (14in) barrel, total length 870mm, total weight 3.82kg without magazine
• Long barrel: 520mm (20in barrel), total length 1025mm, total weight 3.96kg without magazine

The magazine holds 20 rounds, weighs 140g unloaded and 480g loaded.

All of this came from here. --commando552 20:18, 10 February 2012 (CST)

Also, SG 750 is the full auto version, SG 751 is the civilian semi auto version. The 751 is also called the Semi Automatic Precision Rifle or SAPR, so assuming "SAPK" in the picture caption is a misprint, it doesn't apply as this is a 750 (or it could be a 751, can't make out the fire selector markings but either way something is wrong).
