Rem Chokes for c. 1990's Model 870 TC Trap

[beretta boy]

There were apparently 3 unique chokes supplied with these over-bore step ribbed barrels, a Trap Full, Trap Xtra Full and Trap Super Full.
Against all odds, are they still available ... and if so the part numbers ?

F109735 : CHOKE TUBE 12 GA SINGLES .700
F109736 : CHOKE TUBE 12 GA MID HANDICAP .693 PRO BORE
F109737 : CHOKE TUBE 12 GA LONG HANDICAP PRO BORE

You bet, you can order them from our site. Unfortunately, we are currently down for maintenance.

I'm not sure that the quoted items are what you're looking for. Just looking at those descriptions, some are Pro Bore (a different Remington choke system), and the diameters are far too tight for the gun in question.

I have one of the Remington Full Trap chokes and it measures about 0,729"; it is basically cylinder bore. The special 870 TC Trap barrel must be seriously over-bored to make a Cyl the equivalent of Full! I believe they also have a built-in lead-in to the choke, because the inner diameter at the base is the same as a regular RemChoke (~0,741").

I don't have the gun, but it fits in a regular RemChoke barrel, and seems to pattern like an open choke. *Maybe* it's a little smoother machined, I don't know.

Apart from wanting the original parts (which are probably discontinued), I would wager that a Skeet1 and Skeet2 might meet the requirements of XF and SF here, with a Cyl as I described for the F.
