Interesting the stock will fit an M1. Now we need to figure out how to get a M1 wood stock on a M4…… Good luck with sale

Ok, got the new Carrier Comp spring in and no change. I did notice it only does not feed when there are 2 rounds left in the magazine. Ejects prior shell and bolt closes empty - then click. Rack bolt and it feeds up a new shell and will shoot last one as well. Frustrating

Mag extension was original as is the spring. No kinks. 11710 is a LE version. Thanks for the reference

Ok, I cleaned and lubed the M4 and tried again. One fail to feed. Ejected shell, cocked hammer and then click - didn’t chamber a round. Took her home, did detailed clean including recoil spring. Lots of oil there but not gunked up. I did find the magazine extension a bit loose. Also front sight was loose, guess I’ll get to zero in with slugs again. The WW shells seem to have plenty of power, is it possible I have a weak magazine spring? Does not seem to do this with AA loads.

I broke it down this afternoon. Bolt was pretty dry - lesson learned is to make sure it’s lubed up before heading out. Was lubed before storage but that was months ago, guess it migrated toward stock. The Benelli lube is kind of thin, any suggestions on something that will last longer in storage?

I’ve had my M4 a couple years. After breaking it in has run flawless till today on everything fro AA loads on f so keep field to slugs. It has been a few months since I’ve been out, cold weather takes fun away. Today, took M4 to range just to run a few rounds of buckshot and slugs along with my AR. 2 of 5 rounds didn’t get fed, like it short stroked. Have not had this issue before with WW buck, these are not reduced power loads. No issues with 5 slugs. Thoughts? Maybe a bad box? Not what I expected and now wondering about reliability. Am I overthinking this? Will get out a few more boxes of buck in a couple weeks.

Look up the AA12 if you are thinking full auto shotgun.

You might want to adjust the sights to be right on at 50 yards. The difference at 15 yards will be far less than 5 inches off. This approach eliminates the need to compensate under potential high pressure situations.

Did back boring remove some of the chrome lining? Trying to understand how you could machine a bigger opening without getting into or through the liner.

Hopefully it sells well and the 26” barrels become available in a few years.

I purchased a Magpul MS1 Lite, the standard was too wide to fit stock end. The Lite was a disappointing compared to the original MS1 I have on other platforms. It is an easy install though.

I prefer the field stock but wish it was a bit shorter in length of pull. Maybe I’ll get a second one and get the miter saw out………

If you have not yet purchased, look up the model 11710 on Gunbroker, I picked one of these up earlier this year and it comes 7+1 from the factory. No LEO letter needed.
