Conversion project complete - Benelli M4 into an M4 entry gun!


SergeantBernie

Recommended Posts

I promised a little while back that I would post pictures of my completed Benelli M4 entry gun once I had the 18.5" barrel cut down to a 14" entry length.

 

I received the barrel back and was very pleased with the workmanship. The returned barrel looks like a factory part!

 

I've included a few pictures of the firearm, with a couple of barrel closeups. This weapon started life as an M4 model 11707 with pistol grip stock and 18.5" barrel. I registered it as an SBS and proceeded to add the collapsible stock and then searched high and low and finally found a place willing to cut the 18.5" barrel down to 14", and did they ever do a fantastic job.

 

The shop that did the job was Lowe's Certified Guns. Their web address for contact information is:

Here are the pictures for you to see the result yourself. For anybody wanting to convert their M4 into the Entry version, give these guys a call!

The magazine tube simply has the factory included dummy limiter extension unscrewed from the end. The 14" barrel then slides on and the magazine retention screw cap threads directly onto the end of the tube - using the threads previously occupied by the limiter.

 

The tube holds the full 5 rounds just like when it came from the factory.

I look forward to you firing to see if there are any POI issues, particularly with the slugs. I am going to do this to one of my guns as well. I just bought a FA Uzi though and a bunch of mags and need a suppressor as well, so I might be a ways behind you on this one for awhile. Congratulations on a fine looking shotgun. Oh, where did you put the engraving Sarge? This is truly cool cause now you just throw on a std. bbl. and screw on a factory mag ext. if you want to go back to a longer barrel. The long mag tubes are nice, but wouldn't work too good in this case.

Engraved on the right side.

 

My goal was to keep one M4 in the entry configuration, the other in a full length tube and full size stock configuration for skeet shooting!

 

With the entry gun, it is a super simple swap back to the full size gun. Simply screw on the limiter, slide the new barrel in place and screw on the mag tub cap. Done.

I just sent the original 18.5" factory barrel and a copy of my approved Form 1 into the shop doing the mod. Three weeks later I received the barrel back.

 

I don't see much point in keeping multiple barrels, stocks and the like to make sure my gun can be some jack of all trades thing. I like to select a function (SBS fun gun, Skeet shooter, Game hunting, etc) and stick with it. I used to keep all manner of barrels, stocks, mag tubes, extension tubes, pouches, hardware, cases, optics, etc. for all my weapons until I realized I had a mountain of crap down in my basement that was good for cashing in for at least another few weapons that would actually be used. When years would pass and I never used that "spare barrel for just in case I need a long barrel or spare optic, etc. someday" I realized it was a waste and Gunbroker and Ebay became my friends again.

Ain't that the truth. How bought the POI since you got it back, sight alignment and overall quality, does it look like a factory job and all? I appreciate this cause I'm seriously gonna get a 14" barrel and I don't get the the impression from Benelli that civilians are going to have a lot of opportunities for factory barrel conversions. I hope I'm wrong.

Barrels are avilable on gunparts.com. They're not cheap though.

Oh, and what was the tarriff on that baby?

I haven't shot it yet, so not sure about the POI. I would assume unchanged.

 

It looks like a factory barrel. Great work.

 

Lastly - the tarriff on this thing? Am I missing something? I had my 18.5" barrel modded by a US gunsmith, there was no tarriff.

Yeah, how much dough? Excluding the stamp, of course. Did they re-thread for a choke tube or is it Cyl.?
