I may have to ask you how you fixed your 11-87 from Dury's. I bought the same gun from them used, problems cycling, and then when I cleaned it it was super dirty.
As promised, more descriptions with pictures.
1. Most common issue with these guns seems to be fouling of these gas ports on the barrel that prevents the gas from operating the cycle. Make sure these are good and clean. I use a tip cleaner for an acetylene torch,
2. This ring at the end of my thumb is actually a spring that covers two port. Make sure it is in place and covering the ports I have arrows pointing to.
Correct position
The spring is not in the proper position in the photo below.
3. This retainer was not with my gun. It sometimes sticks with the stock during disassembly. This part holds the spring in place shown in 1 above. If it isn't there, that spring may move around. Don't lose this piece. You can't get it from Remington.
The photo below shows it installed.
4. Finally, make sure all the o-rings are in good shape and these pistons move freely.
