Starting in 1983.
Mid 80's
The Invector Choke system was first introduced in 1983 and only available on Citori, BPS, and BT-99 models. Fixed choke barrels were still available as well. Please note that the Citori Lightning model wasn't introduced until 1988. All Citori Lightning models in 12, 16, and 20ga. were only available with the invector choke system (and still are). 28ga Lightning Citori's were still fixed choke only.
The 2 letters NX in the middle of your Browning Invector pump action shotgun indicates that it was made in the year 1993.
Yes certainly it can with barrels intended for steel. It is generally not reccomended to shoot steel through Belgian FN guns no matter the choke. If you have a Japanese made gun with the invector choke system it is likely ok, but not certain. Check the year and be certain that the (invector) choke is rated for steel. The best reccomendation is to consult Browning with the year your gun was made (by serial number) and the barrel markings to identify the time period the barrel was made. They are best suited to recommend a safe answer to this question. Auto5man
Introduced in 1973, the Citori was the first Japanese made Browning. Fixed chokes were the only option until the Invector choke became available in 1983. The fixed chokes and Invectors were both available on the Citori for a few years until in 1989 when the Invector became standard on all guages except the 28ga and .410.
These Japanese made A5's were selling from $800-$1200 this past year.
Your gun was made in 1963. Use the link below to determine choke.
1965 if it is an auto-5. There should be markings on barrel to indicate choke.
No, Remington screw-in chokes will not fit a Browning Auto-5. The Browning Auto-5 uses a different threading system for its chokes, specifically the Invector or Invector Plus chokes, depending on the model and production year. It's important to use the correct chokes designed for your specific shotgun to ensure proper fit and function. Always consult the owner's manual or a knowledgeable gunsmith for compatibility.

The Browning A5 shotgun with a serial number of 210035 was likely manufactured in 1949. The A5 model was produced from 1902 to 1998, and the serial number range for that period can help narrow down the production year. The smooth barrel and Lyman choke indicate specific features that may have been popular during that time. For precise identification, consulting a Browning reference guide or contacting Browning directly would provide the most accurate information.
Look and see if your Browning double auto has a number ahead of the letter A or 2 numbers ahead of the letter A.This is needed to establish the year of production.No Browning double auto could be ordered with a Polychoke,this would have been a after market installation.
