Reviews & Ratings for Lancer Systems Beretta 1301 Competition Extension Tube — 13 reviews — Page 1

I ran into the same issue with fit as others here. My 1301 comp is a newer model. The tube as described by others, does not screw down flush to the hand forearm, which causes the barrel not to push all the way into the receiver. The gap is about 1/4 inch. My fix, was to make a spacer by cutting a 1/4 inch slice off of a 3/4 PVC coupling and dropping it onto the mag tube before the extension tube. This allowed the barrel to push tight into the receiver. The manufacturer should machine an aluminum spacer to solve this issue. I plan on replacing the PVC spacer with one I will make from aluminum. Hope this helps.

I have a 1301 comp gun. (12GA 21”Barrel). It does not screw on far enough to secure the hand guard. I did some research and turns out with “newer” ones something with the handguard is different. My gun was manufactured in 2021 so I would not recommend for any made around that time or after. Otherwise it does look cool with the carbon fiber, too bad it doesnt fit.

First, I called and the representative the help me was very knowledgeable and help me to get it delivered ASAP. The product itself is for my competition Beretta 1301 and is so far function flawlessly. Easy installation. Highly recommend.

The tube installed easily and has performed well. The shipping was a little odd with no updates on delivery date or location.

Evthing about the product was great. Well built it looks like it could take a beating. Looked great on the shotgun. With one exception. It did not fit. I could not tighten it all the way down. Which caused a gap between the tube and the stock.So the barrel and action also were not flush. Which is extremely unsafe. I probably got a defective item. Which such a big mistake I will not give them a second try.

I purchased this +3 extension tube for a Beretta 1301 Competition with a 21-inch barrel. Installation was simple and the instructions were very clear. I did have to trim the magazine spring per the instructions, but again, they were clear and easy to follow. With the extension, I have an 8+1 capacity. The tube extends 1 1/4 inches beyond the muzzle. I installed a Beretta +2 extended choke and I have no issues. I also installed the Lancer tube clamp (purchased from another vendor) with a single side rail that I use to attach a light. The carbon fiber tube is very lightweight and looks great. Overall, this is an excellent product at a reasonable price.
The only negative I have is that OP's tracking system is really terrible. Whoever they are using for shipping should be replaced. I received a shipping notice with a tracking number, but all I could see was that the package was in-transit; an anticipated delivery date was never given.

I recently bought the 1301 Competition 24" for a variety of reasons. The shot gun is phenomenal. Last night i installed the Lancer plus 4 extension tube so i could get 9+1. This evening it was snowing pretty good here in Utah but i didn't care... i was chomping at the bit to go do a live fire function test. I drove up into the mountains with my wife. She stayed in the truck as it was snowing pretty bad outside. I loaded the 9+1 and fired off all 10 about as fast as i could. I was really, really surprised how fast and how smooth the whole setup worked and fired. At that point i was done and put the shotty in the back of the truck and got back in the drivers seat. I said to my wife, "honey i couldn't believe how fast that thing fires". She said, "was that three"??? I said, "no honey, that was 10". She didn't believe me. THAT is how fast this thing can run... THAT makes me very happy indeed. I cut my spring at 16&1/4" past the tube.
Points of note: with the +4 Lancer extension tube, i also installed a GG&G picatinny slot with sling attachment AND the Lancer barrel/tube clamp. The GG&G item seem to be very secure and the Lancer barrel clamp is really awesome. I got mine without picatinny because i wanted it further back, hence the GG&G piece. Lancer barrel clamp is highly recommended. It seems very sturdy and has silicone padding inside so your tube and barrel don't get jacked up.... unlike some others.
All in all i couldn't be more pleased with everything.

Install was easy, just removed the old magazine tube cap and installed the extension as per the instructions that were provided. So far (approx 2,000 shells in) I have not had any issues with feed or loading. Construction is sturdy and light weight.

This extension was great to add those needed 4 rounds to my shotgun for more capacity. I use this gun for 3 gun so it will finish my build for competition. The extension was pretty easy to install, but make sure you follow the directions if you have limited experience with shotguns.

I installed this Lancer +5 on my Beretta 1301 Comp 21". I also added the magazine/barrel clamp from the same company. Installation of both was very straight forward and easy. I have taken it out twice with no problems whatsoever. Works like a charm. Since this upgrade was successful I do not foresee any problems when my 24" barrel arrives. I initially cut the spring to 16" past the extension and felt (no real proof) that it might be a bit tight so I cut another 1-1/2 inches off. In my mind it seems like it was I good decision but not cutting that extra off probably would have worked too.
