My Remington 870 Home Defense Build Thread.

I just started a build porject, with aa 870 12ga for HD duty. I found a used, but in nice & sound working condition non RC barreled 870. I trimmed the barrel to 20.25" inches and used some files to create some knarley teeth on the end of the barrel for the purposes of a defensive twist ram against soft targets (ie a bad guy gets close and I need to work some face to face defense). I have also added an ATI magazine extension to bring my load capacity up to 7+1.

I want to keep it clean but have the capability of a weapon light if there is ever a need. Future plans are to add a Choate MK5 Pistol Grip Stock, Mako 3 rail fore end, Blaze orange follower, a fiber optic light pipe front sight or a tritium pistol night sight ( I will just cut a dovetail in the barrel rip), mag extension to barrel clamp, Mesa Tactical 6 or 8 round side saddle, recoat the metal with Brownells Aluma-Hyde II Matte Black & OD Green, and maybe an extended safety.

Sorry no pictures right now, I will post some later.
 
Suggest you fire a pistol grip shotgun stock with slugs before you buy that Choate. I found the traditional stocks work better for me. I use the Speedfeed stocks that carries an additional four shells are very good - that and a side-saddle shell carrier gives me ten extra rounds.
 
I sugggest before any more modifications you go shoot the thing.

Lots.

After the figurative pile of hulls reaches your shins, you'll have a good idea of what your shotgun needs and what's just bling.

The most tweaked and accessorized shotgun in the known universe will do nothing without a competent shooter operating it.

Become a competent shooter and then tweak. If you still want to.....
 
It's probably a waste of electrons to post this, but building your skills is a LOT more important that adding stuff to the shotgun. The money is far better spent on training and on practice ammo.

Filing TEETH in the end of the barrel?? Nooooooooooooooooooo...

^^AMEN^^
Any lack of absolute symmetry at the muzzle may cause uneven gas pressure that can result in your load going off-axis. It's why serious rifle shooters are quick to correct any muzzle irregularities. Trying to use your saw toothed muzzle might make some BG mad enough to take your toy away from you. If you want to damage soft tissue, that's why bayonets were invented; however, a bayonetted shotgun isn't the most agile HD tool.

I just wanna see the pics....:eek:

Seriously......I've tried just about every "tactical" style stock for it trying to make it the perfect HD shotgun, plus tried a SureFire forend w/light on my 500 but finally came back around to just shortening the factory wood stock a little to fit me better. I should have just gone this from the beginning, would have saved myself lots of cash (better spent on ammo/training) and headaches. :rolleyes:
 
Here is a couple of pictures of what it looks like now. Keep in mind, what it looks like now and what I want to do with the accessories are subject to change. I am still thinking of either slapping on a set of matte finish police style wood stocks or the Speedfeed 3 pistol grip set and calling it a day. I might even cut the end of the barrel off even shorter. I just dont know yet, Im still in the build phase. I understand that with added accessories comes more weight, but its a house gun, not a field gun. The extension is an ATI 7 round tube.

Anyways, heres the pics.

You do know that jagged end on the factory breaching barrels are for just that, breaching a locked door. Not for a nasty looking weapon. The reason is to provide a gas escape when using a breaching load, and holding the gun barrel tight up to the door lock.

My "just for fun" build was easier. I just started with an 870 Express 18" 7 shot synthetic. Replaced the stock, foregrip, added a heat shield with ghost ring sights, and vertical grip with flashlight.
All mostly useless, and unnecessary, but cool looking all the same.
By the way, it stays in the safe most of the time while my S/A XD40 Subcompact residing in my night stand gets HD duty!

Wow, my 870 HD gun is flat out pedestrian I guess. All I did was buy a used 870 Express with a 20" smoothbore slug barrel, load it with some #1 Buck, put one of those elastic butt cuffs on it, and fill the loops with slugs. I experimented, briefly, with a +3 mag extension but I found that it made the gun overly heavy and screwed up the balance so I took it off.
 
Webleymkv, your 870 will do everything mine will. Probably more if you actually have it within easy access for HD. Mine stays in the safe, in a locked room, unless I take it out to defend myself against marauding zombie melons, and pumpkins left in the fields after the season!

Guys guys those cuts on the front are to reduce weight to allow for more tacticool stuff


Practice and this will be more deadly in the hands of a skilled shooter

First understand what breaching is all about.
Simply, your using a shot gun to blow the door knob strike out of the door.

So, first thing, you need an air gap between the end of the muzzle and the door surface. you stick the muzzle up tight against the door, and your going to swell the barrel when you pull the trigger. Next, when you do pull the trigger, you want something to deflect the pellets that may bounce off the door. So not only do you want an air gap, but a venting sections of the end device small enough to not allow a pellet to bounce through
Lastly, when you do place the muzzle device against the door, you don't want the muzzle to slip (lose placement), and that is where the jagged claws come into play.

If I were you, I would just slap a corn cob forend on and maybe trim an inch or two off the butt stock but that's about it. Oh and definitely cut that nasty muzzle off

It is rather disgusting to see a decent 870 be all Bubba'd up for no good reason. At least if the OP saves the stock the barrel can be replaced with one that hasn't been raped with a hacksaw! Too bad he already screwed up the original with the vent rib on it.:(
 
It looks like an awesome movie prop gun but I absolutely would not trust shooting that. It looks like you'd stab into someone and then pull the trigger and the bg would fly back 20 feet into the wall :D
