Judge Fiona Tait told Edward: “The author of the risk assessment on you assesses you at high risk of re-offending.
“For such serious offences there is no appropriate alternative to a prison sentence.
“It is necessary to punish you and deter you and others from engaging in activities for the purposes of terrorism and to protect the public from you.”
Edward appeared via video-link from prison where he had been on remand since September 2022.
He was arrested after armed police surrounded his end-terrace house in Redding, Falkirk, in September 2022 and broke down his front door.
A trial heard that Edward wrote the “the quickest way to someone’s heart is with a high power 7.62mm round”.
Police found weapons and equipment including a crossbow, 14 knives including some with Nazi and SS insignia, machetes, a tomahawk, a samurai sword, knuckledusters, a catapult, an extendable baton and a stun gun.
They also found an air pistol, an SS-style skull mask, goggles and a respirator, fighting gloves with hardened knuckles, pellets, ball bearings, and hunting tips for crossbow arrows.
Prosecutors said it amounted to “an armoury” of weapons.
Edward also had an indoor cannabis plantation that he was growing to sell.
The court heard he possessed and expressed “a set of ideals with a neo-Nazi outlook, incorporating notions of white supremacy, the notion of racial purity of whites, racism, anti-semitism, and hatred of homosexuals and transgender people”.
