​​​​Build your weapon

You can buy an AI&P Tactical one of two ways.  You can buy one of the package weapons or you can design your own and I will build it.  This is providing you stick with the accessories I offer.  If you want something else, I will require a deposit before I order it for your weapon.  Also, I may not have access to that item nor want to install it on a weapon and I will tell you no, you then can visit competitors.

If you purchase a gun from my competitors you have to buy one of their models.    No one out there has the selection of barrels and stocks that I offer.   No sure how they can claim they sell custom guns when you can't design it yourself.    With that said, there are items that you might want that I don't have.    There are more after market accessories for the 870 then all the other pump shotguns combined and I simply can not stock all of them.   There are also items I will simply no put on a shotgun period.   There is a lot of junk out there and I will not put it on an AI&P Tactical Shotgun.   I use the accessories that I know to be duty quality and can stand up the riggors of Patrol work and yes even combat as there are AI&P Tactical Shotguns in the hands of contractors over seas in hot spots where these guns have to perform.   Point is I offer more selection then anyone out there .

All AI&P Tactical shotguns are built on the Remington 870.  I will not build on anything else as I am a Remington Factory Certified Law Enforcement Armorer, certified on the 870 Police and 11-87-Police and will not build nor even work on other weapons as I am not certified on them.  Except for the models built on the Police receivers all AI&P Tactical Shotguns are the same.  All are built on new Remington 870 magnum receivers.  We bead blast them and parkerize them.  We upgrade the trigger groups and bolt.   the bolt on the Express model and the blot on the P model are the exact same bolt, same matte finish and all the same parts except for the extractor.  I change the extractor to the solid steel one that comes on the P model and thus a P model bolt.  The trigger groups are on a polymer housing or you can upgrade to cast but all have the same internal parts.  I have found the polymer to be completely durable and stays cleaner internally.  I have the polymer housing on all of my weapons as do all my employees.

What will vary are the accessories you want on the weapon.  Most of you will be well served with the HD/Duty I model, this stands for Home Defense/Duty as it is perfect for either application.  This is why I  believe the best fighting shotgun I build is the HD/Duty model.  On each model page there will be a list of the accessories you can add and what the cost will be. You may find that if you add multiple accessories that the price will go above one of the other packages.  So pick a package that is closest to the weapon you want and make your modifications from there.

Here are some tips to selecting the right weapon : 

Home owners:  A Basic Home Defense Shotgun should be just that, basic.  think "short is better" and pick an 18.5 inch barrel.  You may not need a two shot tube extension but it helps as you will have a 6 round capacity in the tube and can keep four rounds in the weapon without damage to the mag spring.  A bead sight will serve your need and adding rifle sights to this weapon is a frill you don't need.   The Meprolight Tritium bead like on the HD/Duty is the best barrel for an HD gun.   You do not want a sling on this weapon as it will hang up on every door knob in your home and on the corners of tables, chairs and anything else in your house.  All my weapons will come with sling mounts so if you take a tactical training course that requires a sling you are set. The stock is a matter of preference but the basic conventional stock will serve you well.  If length of pull is an issue I have reduced LOP stocks for you.  I recommend reduced LOP stock or adjustable stocks if you are under 5"10" tall.  You can also add recoil reducing stocks if recoil is an issue.  A shell holder is OK as you can carry different ammo as you check your property.  For most home owners the Cyl Bore choke is OK and the I/C works great. 

Shooters:  If you are like me and enjoy shooting these weapons then think about one with rifle sights so you can get serious will slugs.  The fixed modified choke is the best on a smooth bore barrel for grouping slugs.  If you want to shoot all day ( and can afford the ammo) pick the Knoxx SpecOps stock for felt recoil reduction or for the "Crème De' Crème" get the Mesa LEO with hydraulic buffer tube.  Pass on the shell holder as you are on a range and don't need to get to your ammo fast.  You don't need night sights but if the weapon serves as a defense weapon then think about them.  You don't need a sling to carry the weapon from your vehicle to the shooting line. 

Do not think that you can't enjoy shooting your Home Defense weapon as a range weapon.  In fact this becomes training.  So if the weapon is going to serve as a Defense weapon build it as a Defense weapon.   The bottom line for a recreational gun is put what you want and can afford on it.  I don't mind all the bells and whistles on this one as long as you understand this is a fun gun and not your go to defense weapon and may not be fit for fighting if you have put to much mess on it.

LEO Duty Weapon: This weapon is going to get some heavy use and the fewer accessories the less stuff to bang up and have to replace.  Some of the car racks are not side saddle friendly so think about the Speed Feed stocks with built in shell holders or the SpecOps with a Power pack that carries the extra rounds at the back of the stock or with the Mesa LEO ,mounting the shell holder on the stock of the Mesa LEO.   

I/C choke will get it done for you and should be the choke of choice if shooting any of the flight control stuff out there.   If you are using regular buck shot and slugs the Modified is the way to go.  18.5 police barrel in either bead sight or rifle sight.  Night sights  do have a tactical application when used in conjunction with a light and I have come to view them as a must on this weapon, did not have them back in the day, so yes, you can get by without them but why would you.   You don't want a sling to hang up on the rack, gear shift or other stuff as you are trying to pull the weapon out of your vehicle while you are taking fire.  However, your AI&P will come with sling mounts and the AI&P Tactical Sling of your choice so you have the option to use it.  If you do use it then use it all the time and train with it at all times.

LEO Tactical Team:  Short is best and the Knoxx SpecOPs, the Mesa LEO or the Speed Feed IV-S helps with this.  Put a SWAT plate on the SF IV-S and the LOP is only 12".  The SpecOps adjust down to 11.25" LOP if you take the pad off and that is the best way to have it as you have body armor on and the stock eats the recoil anyway.  The SpecOps Folder is a good call on this weapon. The Mesa LEO with Endine buffer is the best pick for this weapon if you have the money. 18.5" police barrel in Cyl Bore works but any choke will serve.

Ghost rings are peep sights and have no place on a fighting shotgun.  Except for the most experienced shooter they will cause you to give up to much of your peripheral vision and that is dangerous in a fight and can get you killed.    I don't put peep sights on a close quarters weapon so it this is a deal breaker, "Good Bye.

Bead sight or rifle sights and yes the tritium inserts for the rifle sights are worth it on this weapon.  If you go with bead then ask me about the tritium bead sight on the 18.5 police barrel. The rifle sights on the P barrels are designed for you so you can transition from the hand gun to the shotgun with the same sighting system and the rear sight is the about the same distance from you eye as the rear sight of you hand gun they are the same type of notched rear sight.
Think about the sling mounting points as you can waste some money on this weapon with sling plates you don't need.  The best single point I have found is of course the one I make, the AI&P Tactical 1+2 Point Sling.  I also make two types of two point slings that you can see on

Shell holders are a must on a duty gun.  I now feature the Mesa Tactical 6 round Poly Shell holder as it has two retention strips to secure you ammo.  Ammo can't help you if it fell out 20 yards back from where you need it.

 if you have a Speed Feed LE forend you can use the 8 round. The Mesa is the best out there. If you go with the SpecOps the power pack can be a big plus and you can keep slugs ( if allowed ) back there and buck shot in the Mesa. 

The AI&P Tactical models come with a polymer trigger plate assembly.  I prefer these over the cast metal of the Police model.  The polymer is stronger, stays cleaner inside and will never show a scratch or need refinishing.  

The Police Models will come with the Cast Aluminum Trigger plate assembly.   You can op for the Polymer if you ask and I suggest you ask and it will even reduce the cost of your build.

If you don't believe this and want the police trigger plate assembly in your AI&P Tactical model then simply add it for $20 more.  Not because they cost more but because the polymer comes in the weapons I buy to build on and I have to buy the P assembly as a part from Remington so they cost me more.   

Weapon on a Budget:  I love building weapons for you guys but I would be remiss if I did not tell you this.  If money is tight and you need an Remington 870 for protection or duty that is going to remain a dedicated defense gun then I suggest this.  Go to any Gun shop or Sporting goods store and buy a Remington 870 Home Defense model # 81179 or the 25077.  The 25077 will come with a 6 shot one piece tube, bead sight barrel with a fixed Cyl Bore choke.  It is the best value and best made out there.  It is 100% dependable and you can trust it with your life..............Latter when you are in a better financial situation you can send it to me and I will parkerize it, upgraded it with the few police parts and even upgrade some of the accessories if you want.  You will then have a weapon that performs the same as the Remington 870 Police.  However, the 25077 can not take other Remington barrels and the one that comes on it is the only made for it.   So if you may want to get the 81179 as it comes with the Remington LE 2 shot extension and you can use any of the 110 Remington barrels in 12ga on it so it can also be a hunting or Sport shooting gun simply with a barrel change, then after the hunt change back to your HD barrel in only a couple of minutes. 

If the above cost me a sale, that's OK because seeing you get the right gun for you is more important.

So, if want an AI&P Tactical Shotgun do this:

Use the Below information to build your weapon.   Please contact me with all me with questions.   If you only have one or two then e-mail but e-mailing the questions is not the best way.   See, answers can create more questions and more questions create more answers and we end up with an e-mail streme from hell.   Also, I can not tell if you are clear on the answer when it is in an e-mail.    After we talk - You will then e-mail the build Specs and I will reply with a price
