About JBL Magnum 450 Triple Sling Spear Gun (4D50)

The spear gun design that started it all, the JBL Magnum series of guns is probably responsible for more speared fish than all other spear guns combined. It's no wonder; as this durable and accurate workhorse features a 1 1/4" (3.2 cm) drawn alloy barrel, corrosion resistant hardened stainless steel trigger, shaft and point. The JBL756S shaft is made from 17-4 spring stainless for durability and long life shaft is 56" (142.2 cm) in length with a 3/8" (9.5 mm) diameter. The Handles are constructed of two-piece cast aluminum providing strength and ease of maintenance. The Guns overall length is 68" (172.7 cm).

The Magnum 450 features three 9/16" (14 mm) Hi-Mod JBL230 bands with 302 stainless wire wishbones. Tried and trusted, this is one hunting buddy you'll be glad to share a secret spot with. These guns are most suitable for spear fishing among reefs and rocks where heavy penetration is needed. The Magnum 450 is designed for long range and heavy penetration where range is important and heavy penetration is required. The combination of shaft length and the 9" (23 cm) longbutt extension make the gun easier to load.

The JBL823 tip is designed for large powerful fish. JBL's breakaway point has 4"(10.2 cm) wings and 3" (7.6 cm) slip-tip configuration. The Tip is hardened 17-4 stainless and features a multi-braid stainless cable in 1/16" (2 mm) diameter. These tips hang on no matter how hard the fight while minimizing damage to your spear shaft. Their low-profile, double barbed design allows for pinpoint accuracy and dependable deployment. Don't trust a once in a lifetime fish to anything else.

The Gun is equipped with the JBL518 Shock Line. Sometimes we miss or we shoot a large fish and the recoil can pull the gun out of your grip, which ever the shock line will keep you in control. The Guns range is 27' (8.23 meters). The Gun is totally made in the USA.

I dive for abalone and spear fish in north CA, and this gun is great anything from small sea trout to ling cod and halibut, one down side the metal ring on the spear that fits into the end of the gun, if your tip gets unscrewed you will loose it, but still a great gun.

This was the first gun I bought. It did not work right from day one. I had been using my friends AB-Biller and the two guns do not compare. Very inaccurate and very noisy underwater. After one shot, all the other fish leave the area because of the noise it makes. I would recomend AB-Biller or OMER.

Comments about JBL Magnum 450 Triple Sling Spear Gun (4D50):

After reading several reviews I've decided to make my own for those of you that are newer to Diving. This is a more advanced gun. Shooting smaller prey this gun isn't needed, nor would I recommend, this is a large gun for large prey! Due to a closed muzzle you must be AT LEAST the length of your shaft to your target if not longer if you wish to keep your shaft in good condition and not bent, or destroy the front end of this gun. Below I've bullet listed some pro's and Cons of this purchase for those who don't want to read a novel.

Pro(S)
-Accurate
-Powerful
-Out of the box great price for what it is.
Con(S)
-Closed muzzle
-Butt Stock easy to lose if your float line free diving, I lost mine after the first fish.

Regarding others negative comments, people listed hard to use; well it's 5'-8" long it's a large gun, your going for large fish, not beginner fish. If your finding it hard to load it's possibly your technique not the gun! Some say this gun is bulky, well big fish take bigger guns! For those of you that are looking for a 'quiet' gun get a Pneumatic gun they are quiet and fast to reload. a long range gun like this can and does require more than one(1) wrap of your shooting line. With a few easy modifications this gun is a steal!

    Comments about JBL Magnum 450 Triple Sling Spear Gun (4D50):

    I am a female hunter and this gun is very easy to use. It is accurate, light and appears durable. The only negative so far is that despite a good rinse the metal comonents of the muzzle and handle appear to corode slightly. Overall, the pros far outweigh the cons.

        Great gun for the money - a best buy! Good range, easy to load, well built. Good starter gun that you can use a lifetime. When storing gun, it helps to take off extension butt so you can spray insides with oil. Otherwise the safety & trigger can get sticky for bit until you work it out.

          I have been a Dive Master for years and have tried
          several more expensive guns and i always go back to this one. its simple to use and realize this is a GUN it needs to be taken care of. but if you do lose or break a part they are always easy to find.
          ** HINT ** spray your spear and channel (ONLY) with PAM no stick before you go and rub your bands with BAG BALM after you clean your gun before you put it away.
