Great option
Very pleased to have the option of the front mounted stud. Here on the farm the side plate hangs on everything in the tractor and truck. Have an older 20 ga model with the side plate and wish I could get one like this. Great quality, service and shipping from Wilsons as usual.
Easy Removal
A squirt of Kroil or gun lube at the open end and allowed to run down between the retainer and the tube wall will facilitate an easier removal of the retainer from the shot shell tube.
Excellent and Simple great combo
First upgrade I have ever installed on a shotgun before and it was very very easy. This went on an H&R Pardner Protector with an 18.5 in barrel it does require a little work the dimples in the tube need to be either ground down or drilled out for the follower to pass through but other than that its a breeze to install and has held up fine and I expect it to continue doing so.
Awesome Product!
Got this for my H&R Pardner Protector. Fits on great and didnt come loose after a bunch of rounds fired. Quality construction! Thanks Wilson Combat!
Exceeded Expectations!
Incredibly fast turnaround from ordering to my door! I gotta say that it exceeded my expectations. Great Quality piece. Excellent fit and finish. Very nice knurling. Fits perfectly on a H&R Pardner Pump.
Great Extension!
Incredible quality, very well made extension. Does not disturb the balance of the shotgun like the +2 extensions do for me. All around great product like everything Wilson makes.
1 Shot Extension Tube
I just received the 1 shot extension tube and increased my 18.5 inch H & R Pardner Pump from a 5+1 to a 6+1 with no problems. I didnt want to drill holes, so I used another method to smooth the dimples out and no holes in my gun. Great quality product.
easy upgrade
Ordered this mag tube extension.....it was easy to install, and works perfectly. If you have an 870, this is a no brainer upgrade!
