The first online purchase I made at this gun shop is worthy of framing with an unbeatable impression. I ordered several models of pellets… and the truth is that they arrived like a bullet. They didn't even take 18 hours! I received the order in perfect packaging, which made it easier to preserve during transport. A single box of pellets arrived with them quite dirty, as if there was little turnover of that item, but nothing out of the ordinary and that can't be solved by cleaning them before firing them. In short, excellent service and good product. They have gained a repeat customer.

They helped me over the phone and recommended a rifle based on the use I was going to give it. Excellent service. The shipping was incredible, in two days it was at my house (Asturias). I had doubts about buying this type of product online but it was a success.

The type of choke you choose will depend on how far you are shooting and how accurate you want it to be.

Hunting shotguns usually include five shock models:

*****Smooth, ****Quarter, ***Half, **Three Fours, *Full : narrowing star ratio.

Each of them will have a different role and impact on the dispersal of pellets. The smooth choke will offer a very open dispersion, while the full choke will produce a very tight dispersion.

How to choose the Chokethat I need? That will depend on the distance and the pellet cartridges, although as a guide we can be guided by:

Chocke | Optimum shooting distance:

Smooth | < 20m

A room | ±24m

Medium | ±28m

Three quarters | ±37m

Full | ±47m

THE best choice is experience with your own hunting rifle.

The number of choke stars or grooves indicates the reduction in diameter.

Full or full choke = * (1 mm reduction)

3/4 choke = ** (0.75mm)

1/2 choke = *** (0.5mm)

1/4 choke or improved cylindrical = **** (0.25 mm)

Smooth or cylindrical = ***** (0 mm)

Sometimes chokes are marked with a letter:

F for full choke (Full choke)

IM for 3/4 choke (Improved Modified)

M for 1/2 choke (Modified)

IC for 1/4 choke (Improved Cylinder)

C for smooth or cylindrical (Cylinder)

There are various chokes available for Beretta shotguns. How to identify the correct one?

It's not that difficult since each shotgun only accepts one “Family” of chokes in a single gauge. Within these parameters you can choose the model that you like the most (examples of models: interior, exterior, ported, black edition, etc.).

2 main variants are the data you need:

Family: Mobilchoke, Optima- Choke, Optima- Choke Plus - Choke HP (latest model developed)

Gauge: 12, 20, 28, 410

Visual method to identify the choke I need:

The fastest way to identify the correct family of a choke is to directly read the etched markings on the choke.
Note: Mobilchoke may also be marked PB or ST.

Choke Measurements Method:

In this case, only your current choke is needed to verify the measurement from the end of the thread to the end of the choke. (for an extended choke, we have to consider from the end of the thread to the end of the inner part of the barrel.

Barrel marking method:

In this case, the barrel is only needed to verify the etched mark near the caliber mark.

If there is no mark (only the caliber appears): MOBILCHOKE
If OB appears (following the gauge marking): Optima-Choke
If 3 1/2" appears (following gauge marking): Optima-Choke Plus
If OB HP appears (following gauge marking): Optima-Choke HP
