Aluminium Railguns are a sophisticated and durable range, suited to every conceivable condition in the UK or abroad. Though heavier than our premium carbon guns, this range can tolerate very rough handling like no other gun on the market.

Our Aluminium Railguns are designed to give you years of use, and shrug off blows and scuffs in the boat or amongst the rocks.

For those looking for a more economical but equally potent alternative to our premier carbon range, Aluminium Rail guns are the perfect choice. We are happy to put our Railguns alongside anything our competitors produce. You will notice the difference in build quality at a glance.

Rob Allen aluminium railbarrels have the same dimensions as the carbon barrels. The rail level lines up with the profile of the mechanism and the muzzle. The integral rail is part of the barrel, thus increasing stiffness and reducing flex. This makes the guns deadly accurate.

The rail barrel is manufactured from aircraft grade aluminium with a wall thickness of 1.45mm and the mechanism is manufactured from glass reinforced nylon and has a solid 316 stainless steel sear.

Rob Allen Vecta Aluminium Rail guns are available in lengths from 70cm to 140cm. 70cm to 110cm are ideal for standard fishing in the UK. 110cm to 140cm are perfect for clearer water, bigger fish, and more skittish species such as bream. We tend to use 100cm to 140cm guns off Portland Bill. 130cm to 140cm guns are well suited to bluewater fishing. A 140cm with double 16mm rubbers is easily capable of landing wahoo and yellowfin tuna. The current British Record Gilthead Bream was shot at long range with a 140cm Aluminium rail gun with twin 16mm rubbers.

We have three main configurations: 16mm bands with 6.6mm spear ('Sparid'), 20mm bands with 7mm spear ('Caranx') and double 16mm bands with 7.5mm spear ('Tuna'). We are able to supply other combinations of bands and spears. The barrels, fittings and muzzles are identical between these three main gun fits.

What size speargun for UK spearfishing? – Our recomendations:

The general setups for UK spearfishing are shown below and can be easily selected with the option choices.  There is no right or wrong speargun length and is often simply down to personal preference.  However that said people tend to prefer shorter guns for low visibility conditions so they can manoeuvre their gun quicker, or for hunting caves, holes and tricky environments.  Longer guns are used in better visibility or when a longer shooting range is desired.  It would be safe to say that most UK spearfishing is undertaken with an 80cm or 90cm length speargun.

Feel free to give us a call to discuss any specific requirements but as good all round setups we recommend the following:

70cm length speargun:

6.3mm Spear, single wrap line & single 16mm rubbers

80cm & 90cm length speargun:

6.6mm Spear, single wrap line & single 16mm rubbers

100cm length speargun:

6.6mm Spear, single wrap & single 20mm rubbers

110cm and 120cm length speargun:  (Our personal favourites for UK spearfishing)

7.0mm spear, double wrap & twin 16mm rubbers

Anything over 120cm will be for blue water spearfishing will normally be:

7.5mm spear, double 16mm rubbers & double wrap.
