I call this my Sig SPR.
She shares alot with an AR type, similar dimensions,wieght,ammo,scope and mount.



Brugger & Thomet Quad rail, SwissArms cheekpiece.The B&T quad rail has
a nice tight fit ,and been most impresive.



GG & G bipod snaps up or down , good and tight.




Tritium flip up sight


Rear drum sight


Adjusting the sights with sight tool




Larue SPR scope mount, with Leupold Mark4 3.5-10 L/RT ill. mildot reticle.





The Larue mount is perfect , it is absoloutly the finest scope mount made.


Accessories -sight tool,bayonet,cleaning kit,stripperclip adapter.

I'll trade you a Win. M94 .30-30 for it. These will soon be "rare", "hard to find" & a 'real collectors item" very soon now.It comes with a broken Old Timer knife(also "rare" "hard to find" & a "real collectors item") & straightend coat hanger that is bent on the end to hold a cleaning patch. It all fits into a rolled up army surplus wool blanket. Could be a good trade for you.

Is the B&T rail handguard free floating?

I know this is arfcom, but seeing these pics was refreshing.

I dream about a 550. Part of it is the unobtainium they are made of.

There are alot of sig guys who would cringe to think you added aftermarket stuff to the rifle and heaven forbid..........actually shoot it.

I certainly shoot this rifle, thats what they are made for !!

The B&T rail is also Swiss made the cheekpiece is SwissArms/Sig, so its close to home as far as upgrades go.

She shoots moa all day with irons and surplus ammo, and 1/4 moa with a scope.

I'd trade both of mine, I don't want/need kids anyway.

That rifle is incredible, and the level of accuracy you describe is amazing. I think I'm going to kill myself now.

ETA-I'd also love to know even a hint at how you acquired such a toy. Also, how heavy is that with the rail? The 551 SWAT that I shot seemed heavy for such a small piece, but it was well balanced.

Take a look at the Crapco 556. On the SigArms website, there are two pics where the flash suppressor is incorrectly installed. Maybe someone has already pointed that out, just though I'd share my feelings of being jipped.

1/4 MOA thats outstanding, thats right up there with GAP bolt guns and considerbly better than real SPR's, I really am going to have to look into the new 556, i just hope it has the same potential as the 550

When I say it shoots that well with surplus ammo, it is a slight exaggeration. The Swiss GP90 'surplus' ammo, is as good as match grade.

GP90 is hard to find , but not overpriced compared to other high end 5.56 ammo.

Thanks all,

For all the kind words, it took my time doing the pics to share , not to show off.
It is my pleasure to share with my ARCOM brothers.

Pretty soon , Sig will be selling the new US version soon enough. Although I have NOT been impressed with recent/modern Sig pistols and service, I think they will try to get the rifle right.

Super nice, but 1/4 MOA? Sounds unlikely for any semi auto no matter how nice. In fact, I don't think David Tubb ever was able to build a 1/4 MOA semi auto. I will read up on 1/4 MOA semis to double check how rare they are.

Read up on how the barrels are made it is amazing.

I hope to find some targets, and will post them.

Here is a link to a couple of SPR builds that do that well - in fact, on page 3 there is a 15 shot group that can be covered with a dime (with room to spare). Lets also not forget the HK PSG1 - it is one fine shooting rifle too.

I a;ways wondered, how are their barrels made?

This is taken from bighammer.net , these are not my words , this is a cut and paste.

Or you can go to biggerhammer.net to find out more.

Here is the cut and paste, and I hope they dont mind me doing this.

----------------------------------------

In order to obtain the firing accuracy required by the GRID, SIG has in particular modified the barrel - manufacturing process. The chamber is now forged at the same time as the bore so that irregularities in alignment which can occur when the bore is hollowed out after hammering are avoided.

Although the general design of the new rifle owes a good deal to that of the SG540, SIG has introduced numerous improvements which make the SG550 one of the most carefully conceived assault rifles of the present generation. A description of the gas operation is the best way to support this statement.

Instead of entering the gas cylinder directly, as is the case with many other gas-operated weapons, the gas passes through the port of the gas intake into an Lshaped channel machined in the piston head. It is thus directed forward towards the cylinder head/gas regulator and the build-up of pressure over the piston head makes the piston recoil, transfering its energy to the bolt carrier, which in turn unlocks the bolt. As the piston moves back however, the gas port and the L shaped channel move out of alignment and the piston head thus blocks the port, cutting off the supply of gas to the cylinder.

The latter is fitted with an exhaust port through which the surplus gas in the cylinder and the combustion residues are evacuated. This system ensures that only the exact amount of gas needed to impart the necessary momentum to the moving parts is admitted from the bore. The moving parts are therefore subjected to less mechanical stress, increasing their useful life.

The rifle is fitted with a two-position gas regulator, which is adjusted either by hand or, if necessary, with the aid of a cartridge or bayonet, so that if the weapon becomes seriously fouled the supply of gas can be increased. With the same aim of reducing wear on the most used parts, the interior of the receiver is fitted with rails which guide the bolt carrier and bolt, thus reducing the transversal stress.


While SIG has made no great innovations in the fabrication of the metal parts of the SG550 and SG551 compared with the SG540, the company has nevertheless increased the strength and rigidity of the receiver, particularly the magazine housing and the rear part against which the bolt assembly recoils. It has not been considered necessary to chrome the bore, but the barrel, which is drawn from a chrome- nickel -steel bar, is thicker, particularly at the chamber, where its diameter is 28mm.

Great attention has been paid to protecting the exterior surfaces because of the severe conditions which can be encountered in Switzerland. After being phosphatised but before finishing, the metal is subjected to a treatment which smooths the surfaces and which, according to SIG, greatly increases its resistance to knocks and to corrosive agents.

The cook-off threshold of the ammunition is high, being situated at 240 rounds/min compared with the 160 rounds/min specified by the GRD This results from the carefully calculated thickness of the rear end of the barrel which ensures good heat diffusion during tests, the highest temperature was recorded at a point 1 5cm from the chamber - and from the good ventilation given by the openings in the handguard. Operating safety is also increased by a safety catch which prevents the hammer from falling until the breech is completely locked.

In accordance with the specifications, the rifle withstands the firing of at least 600 500g grenades with the stock braced against concrete (the manufacturer claims to have fired more than 1,000 without incident) and also the traditional 2m drop test, from any angle.

The barrel is fitted with a flash suppressor with the standard diameter of 22mm. There are plans to design a new bayonet for the rifle even though the current service model can be fitted. Particular care has been taken with the shape and orientation of the flash-suppressor slots in order to reduce muzzle flash and avoid sand or snow being kicked up by the gas escaping once the bullet has cleared the barrel, when firing in the prone position.

------------------

end of cut and paste

I would also like to add that the flash hider is machined out of the barrel, not a screwed on attachment.

For more info you can also go to swissrifles.com

I hope all this helps.
