Our carbon railguns are the pride of our collection. Light, strong, powerful and precise. Available in a variety of specifications to suit your needs, our range of carbon railguns can cater for every situation. These are premium spearguns with very high build quality, and will give you years of use in the toughest conditions.
Rob Allen Carbon rail barrels are pullwound in a continuous process using 3 to 4 tons of tension. This allows the fibre loading to be maintained at a much higher level than in conventional mandrel wound tubes as used by other manufacturers. As 100 % carbon fibre is used at the highest possible loading, along with an integral rail further adding to the stiffness, the Rob Allen Carbon railbarrels are the best in the world.
Each barrel is pressure tested twice – first with air immediately after the initial pullwinding process and then after assembly in our hydraulic test chamber to the equivalent of 40m depth for one hour.
The Black Glass reinforced Nylon mechanism comes standard with a Stainless Steel Line Release. Designed with Carbon Barrels in mind, the internal spigot and external shrouds grip the barrel to avoid stress at the screw holes. Guns from the 1100 models upward have a "muzzle brake" weight fitted internally behind the muzzle. This balances the gun when aiming and reduces muzzle lift and recoil on firing.
Rob Allen carbon railguns are available in lengths from 70cm to 160cm. 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 160cm are well suited to bluewater fishing. A 160cm with double 16mm rubbers is our most formidable bluewater gun, quite capable of landing any tropical gamefish at long range.
We have three main configurations: 16mm bands with 6.6mm spear ('Shanti'), 20mm bands with 7mm spear ('Sutu') and double 16mm bands with 7.5mm spear ('Zulu'). We are able to supply other combinations of bands and spears. The barrels, fittings and muzzles are identical between these three main gun fits.
The various options, other than rubbers, are available as no cost options on our exclusive carbon range. You may choose what thickness spear is fitted to the gun. Only one spear is supplied with the gun, you can order extra spears using the accessories menu.
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.
Rob Allen 160cm Carbon for Tuna
Colin and I use the 160cm carbon guns for big game off Ascension. The guns are very long ranged, accurate at over 7m and with enough punch to penetrate a 200lb tuna. Traditional thinking has it that large teak guns with slip tips are needed for tuna. Colin and I have landed 4 tuna over 200lbs and numerous tuna over 100lbs with these guns. The ease of handling, lightness, power and accuracy make these guns perfect for hunting huge yellowfin tuna.
