Choke Interchangeability

[Blastattack]

I recently acquired a Remington 870 barrel and it came with one Remington marked choke, and two other chokes without any manufacturer markings. All chokes share the same thread pattern and configuration, but are about 1/2” longer than the Rem-Choke. I believe they are Winchester/Browning Invector chokes. Is there any reason I can’t or shouldn’t use these? They seem to fit perfectly.

If they fit, there is no reason you shouldn't use them. I would double check the fit to be sure there is no step inside the bore.

Have said that, I believe the Remchoke is unique. It might look similar to the Invector Plus chokes but I don't think they will interchange. You say they are 1/2" longer than your factory choke, that extra length must be sticking out beyond the muzzle? If so that is simply an extended choke tube, which is fairly common with aftermarket brands.

Pics of them side by side would really help.
