Are there slug barrels available that will fit an 870 Express HD with the extended magazine tube or do I also need to change the magazine tube? Where does one get a magazine plug or am I better off making one out of 1/2 dowel rod?

Just take off the barrel clamp, magazine extension and coupler. Lately Remington has been factory-tightening the couplers to apparently excessive degree on the HD guns- it may take a pair of slip-joint pliers with leather or several layers of terrycloth padding to get the coupling off the magazine tube so you can remove the barrel.

You will want an old style slug barrel with the detent installed in the barrel ring to keep the magazine cap in place, if you plan to use the barrel without the extension. You'll need a magazine cap to replace the coupler and magazine extension also. You will want to get the old style magazine cap with dimples around the inner edge of the skirt so they engage the spring-loaded detent in the barrel ring. If you want to use the extension with the rifle-sighted barrel, just reinstall everything you removed to take off the issue barrel.

Where does one get a magazine plug or am I better off making one out of 1/2 dowel rod?

Wallyworld or any of the big-box sporting goods stores should sell a one-size-fits-most plastic magazine plug for a few dollars.

If you go the DIY route (cheaper, but...), be sure whatever dowel you use is of a diameter that will fit inside the magazine spring's coils with enough clearance for it to function properly. Start with a length that's a bit long, and shorten it as you experiment to be sure you can get two shells in the magazine but not three. Round the ends of the dowel nice and smooth to keep from chewing up the magazine spring, too.

Thanks Lee. This approach is what I was thinking.

308,

Were you able to take off the screw? I hear what he's saying about factory tightening. I almost stripped the screw trying to take the screw off!

Thanks.

Not sure which screw you are speaking of; I have taken the magazine apart (removed the extension) to clean it when I purchased it. Mine wasn't unusually tight as I recall.

I believe that Remington offers an 18" rifled barrel with sights. Any drawbacks to this barrel that anyone is aware of?

One very useful Rembarrel is the 20" one with open sights. Some have Remchokes, others have a bit of choke, some have none. Available in all finishes.

All work for defensie and venison acquisition.

I have been checking the prices for an 870 Express 20" rifled barrel with open sights. The Remington site lists them for $201; it seems like the going rate is around $190. I only paid $279 for the whole gun brand new. Oh well, I guess it is what it is. Are the after market barrels - Hasting - comparable to the Remington?
