remington 1100 barrel thickness
how thick does the barrel of a remington 1100 (12ga) need to be to have it tapped for a choke?

quote:To ensure that your barrel is of adequate thickness for your choice of choke tube simply measure the outside diameter of the barrel at the muzzle with a caliper or micrometer. 12 gauge barrels must be at least .845" to accept Rem-choke and Win/Browning/Mossberg chokes, at least .825" for the Tru-Choke tube or at least .805" for Tru-Choke "Thinwall" tubes. 20 Gauge barrels must measure a minimum of .705" for the Tru-Choke tubes.
Maximum bore diameters also apply, although this is rarely an issue unless the barrel has been altered by back boring or jug choking.0 -
Not only is the OD & ID important...The concentricity of the OD to the ID is also an important factor...The worst for the lack of concentricity I've seen are the older fixed choke remington 1100 & 870 barrels...JMHO...

Jim is right on the money. For the price, I'd look for another barrel with screw in chokes. In the long run a better deal.

I had a 20 gauge 1100LT20 threaded for Colonial Arms Thinwall Chokes.
The barrel had to be shortened to get to thickness sufficient to accept the Thinwall chokes and end at a ventilated rib support unless you will accept the additional work to install a support.
My barrel ended up at 25 1/2".
This conversion worked out beautifully and the gun is both very handy and shoots very well.
The Thinwall chokes work better than others to minimize the amount of barrel removed.
At least that was the case when I had mine done about six years ago.
I'd recommend going that route.

1988RRC,
Unless yer just dead-set on keeping & modifying the orig barrel, ya might want to consider one of the aftermarket types w/ tubes (Hasting, etc). They used to be avail thru Midway (iirc) & were Xlnt quality.
Am surprised to hear of the eccentricity issues of the older Rems. However - for the newer ('95-on) style, I could understand it.0 -
"Am surprised to hear of the eccentricity issues of the older Rems."...........I had one in the shop, older 1100 barrel (for the 12 ga. fraim size" bore was so far out of center that even thin wall tubes couldn't be used. 0
