Swiss Arms CQB

And obviously you have just stated your opinion, so whats the opinion of Swiss Arms?
I`m sorry man but I`ve spent way too much money at your store to be nickle and dimed about some "defect" and it shouldnt cost you a penny either . Any way you wanna slice it a upgrade is a defect that they obviously have addressed for a reason, full auto or not. I`m not worried about Iraqies shooting me but what if it blows up and injures me or someone beside me and there are known issues?

Lets hope it doesnt blow up in somebodys face, literally.
I know mine wont as its just a wall ornament anyway..

No I stated Swiss Arms policy. It isn't a defect, it isn't dangerous and it does not apply to the CQB. It is a product improvement to enhance the lifecycle of their full auto SG552s. Why you would think that it poses a safety problem is beyond me, even Bigred and KevinB who have used the guns that broke have not suggested that the guns posed a risk to the shooter. They simply "broke".
 
Well, When I bought my last "upgrade" I never heard a word about this "improved gas valve" either.

Did you get this at the same time? Is there any other "upgrades" and as far as they just broke..... you really cant predict how something will break but you can help prevent the break in the first place, especially if we are told about it.
 
What's different about this improved gas valve? Port sizes? Different metallurgy? Plated to prevent fouling?
 
My guess it is about gas port size.


IMHO, Swiss arms should provide these upgrades to the owners at cost.

I beleive its a smaller gas port on the new one -- the larger opening on the old one really beats the gun up.

- I took some pics of the old style recoil guides and will explain the problems we have had -- there is no danger to the shooter (other than the fact his primary no longer works) if the part fails.

I will upload them after dinner

Hey JR,

That's good to know! Glad us CQB owners don't have to worry about that aspect! I've been "babying" my CQB, I rarely shoot more than 100 rounds at any one trip to the range. Would you recommend the new poly recoil guide mentioned earlier? Or is this something that should only concern full auto SG552 owners/users?
 
Yup, TS has one in stock. I'm kinda into the waiting though .. so I can save!!

If anyone has the cash right now, that's the place to get it.

Even the very first ones you brought in? Mine is from the first batch..

So your saying I should just STFU and shoot the S**t out of it? Whats your take on having a krink on it? Will it increase gas pressure, causing more stress?
 
Here are the pics of the recoil guide and springs I took.

These three are used -- but scavanged out of guns removed from service - and I brought down to fill the void.

I played with contrast on one pic so you can see the area that are being abused -- one looks like it is still GTG -- the other two look like they may be on their last legs -- and there seems to be two or three different versions -- all of these guns where brought in on a US DOS End User at the SAME time...

If you want confirmation send me a pic of the gas valve. The new updated ones are silver. The gas port pressure issue concerns full auto use in the SG552. So there should be no problems on any CQB. The breakage issues all resolve around the recoil spring guide, and from there the bolt carrier. They have never effected lock up, or receiver life.
If you look at KevinBs pic, you can see that the spring on the left is also shot, the springs need replacement periodically too, just like any other system.
 
Redleg, my CQB came with the steel spring guide rod, I'm guessing it must have belonged to one of the initial import batches, here's my gas regulator, it appears "silver", do I have the current, updated valve?

James -- This was a big lesson learned -- dont by the neatest shiny tool on the planet - 1) If you dont have an armorer 2) Dont have a part replacement schedule 3) or a regular method of reparing.

With the replacement parts coming in -- the decision was made to remain (our side of the company) with the Sig's for issue. The M4 purchase was shelved.

Cheers

So the current CQB's ship with the metal guide rod as the polymer one is only required in the 552?...I thought NOT.

If the new CQB's have them then they should be shipped out gratis to everyone who bought with the metal one...unless theres another BULLCRAP excuse that we haven't heard yet.

Every agency that has 552's has been given the poly rod FOR FREE...but of course they didn't pay $3000.00 for their guns so it's not a fair comparison.

The metal guide rods are no longer in production. So I don't see your point. The CQBs are made using available SG552 parts. This is done to keep prices down. Making small numbers of parts exclusively for the Canadian market can get pretty expensive. I don't think it is unreasonable of SAN to eliminate the steel guide rods completely in all their guns and use only one, even if it is optimized for a FA gun.

The guns carry the same warranty regardless of the parts used, and to date there have been no related complaints (not withstanding this thread).

I can't comment on what agencies have received parts or not, other than to say, that we have not replaced any parts for any agencies. Nor have any approached us for replacement parts. Since their guns are mostly FA though, it would seem to be a reasonable request if made.
