choate 5 round extension on 870

JBrady555 · May 24, 2012

Hey guys I just put my choate 5 round extension on my 870. I haven't had a chance to shoot it yet. First impressions are that the tube is solidly constructed and also has a nice sturdy barrel clamp that came with it. I didn't trim the spring any, it was about 16 inches longer than the total tube length and I decided to just shove it all in there. I don't have any ammo on me right now to test the load capacity to make sure I can get 10 rounds underneath. Anyone else have one of these? I'm a little weary of the reliability of firearms after modification and just wanted to see if anyone has had any problems with these mag tube extensions. Thanks for any info.

No need to be "LEERY" of the reliability of your shotgun using the Choate mag extension - You should not trim the spring that comes with it, the spring is a specific length and poundage so that it will function properly when installed.

Personally, having an 18" barrel, I prefer the +2 extension.

Choate has been making extensions for almost as long as Remington has been making the factory extension.
Choate is a very good quality unit and in 30 years I only saw two that had problems.

As above, the spring is the correct length, don't cut it off.
Note that the length of UNFIRED shotgun shells vary so with some shells you may not be able to get the last shell in.
Don't cut the spring trying to get the shell in, try a different brand of shells.

thanks for the replys, I think I have the 26" vent rib rem choke barrel, so my extension comes about 2" shy of being flush with the end of the barrel. Now I'm thinking of a Choate Mark 6 thumbhole stock which hold 5 rounds in the stock, bringing my round total to 15+1 on the gun. If I get a 5-10 round side sadel after that I could have 20-25 rounds on the firearm. Talk about heavy, lol!!

Heavy and unbalanced and hard to move quickly and properly - something to think about if this is to be some form of HD/SD gun as opposed to a fun gun

My 1100 has a 26 inch Hastings Wad-Lock barrel on it with a Choate extention...10+1 is great for combat shoots...

I've got a 4 round extension on my 11-87. No issues and I use the gun in local 3 gun matches. I did use the stock follower and not the one included in the kit.

Unless you are playing "Shotgun Games", why in the world would you need a 10-round pump shotgun?

It will slow you down in a real life situation, and if you miss, it makes no differance how many times or how fast you miss.

In my opinion ,Learning to combat load a shotgun makes long mag tubes a non issue unless shooting a three gun match. I like my shotgun as short and light as possible.

I understand what you guys are saying but I don't think its that bad of a thing to sacrifice a little bit of extra weight for double capacity. The gun feels really good even loaded to the max, its not like you added 10 pounds or anything. I guess its just personal preference.
