I found TYPO !!

I tried find quick in
...cfg/sourcemod/weapon_restrict.cfg
weapon_sg552
Nope from first time. I ctrl+F search 552
I found it but have been write

// Restrict/Unrestrict -1 unrestricts vesthelm for ct
// -
// Default: "-1"
sm_restrict_sg552_ct "-1"

// Restrict/Unrestrict -1 unrestricts vesthelm for t
// -
// Default: "-1"
sm_restrict_sg552_t "-1"

I thought must be come with zip file so I renamed old cfg and let plugin create new one.
No, same description

I peek source file and found typo in
...scripting\restrictinc\commands_cvars_tries .sp
Line: 187, 188

PHP Code:

    sg552ct         = CreateConVar("sm_restrict_sg552_ct", "-1", "Restrict/Unrestrict -1 unrestricts vesthelm for ct");
    sg552t             = CreateConVar("sm_restrict_sg552_t", "-1", "Restrict/Unrestrict -1 unrestricts vesthelm for t"); 


I fix and compiled myself
