THE IMAGE ABOVE IS A PAID ADVERTISEMENT
Is the charging handle in the SR-556 proprietary? I'm wondering if I could install a 3rd party charging handle later.

I just put the new raptor one on mine. I was impressed that it was better built and smoother than the stock one.

If it's an AR-15 platform, the charging handle grooves in the upper are standard.

The charging handles, especially that latch can usually be improved by replacement and the replacements usually do not cost that much (IMO).

That said, I've only upgraded my charging handle for cosmetic reasons :)

Thanks for the info all. I suspected as much but figure I'd ask just to err on the side of caution.

The SR-556 is mil-spec - this ought to help you with any mods you are considering.
