<div align="center">BL SERIES

Provided By Boogieman - <a href="http://www.advancedspuds.com">www.advancedspuds.com</a>

These are the BL Series launchers, BL standing for Breech Loading. They are pretty straight forward launchers, offering great fun at a reasonable price. I would highly recommend them for a first launcher, they are not too high tech, but offer breech loading, a very nice feature for any launcher. Don't be fooled by their looks, they pack a punch! Best of all, the entire gun, including igniter, can be built for under $15!

I would highly recommend the BL series for anyone just getting into spud gunning, Its cost and ease of construction makes it a great launcher. It is also fairly easy to upgrade for once you start wanting more power! It is also recommended to anyone, whether you are a spud gun beginner, or a seasoned veteran, you will love it's reliability and ease of use. At the heart of the BL series is the breech loading system.

The launcher is assembled as follows (listed rear to muzzle): 3" Female adapter with clean out cap 12" of 3" sch40 PVC pipe 3" coupler 3" to 2" reducer bushing (spigot x slip) Either: A: 2" FPT Adapter (spig x FPT) or B: 2.5" section of 2" sch40 PVC pipe Female Adapter (slip x FPT).Next you will have your pass through barrel which will be 51" of 1.5" sch40 PVC to give you a 1:1 ratio (don't believe all the old 1.5:1 ratio stuff, for this chamber, a 1:1 ratio will outperform a 1.5:1 ratio.) Feel free to adjust the barrel length to suit your needs. The barrel will have a 2" MPT adapter as well as a 2" to 1.5" bushing on it.

Now for the ignition. Do whatever you wish, but I would suggest a lantern lighter. The chrome thing on the launcher near the end cap is a lantern lighter with a knob that I fit on it. Also, keep the lantern lighter towards the back of the launcher, this way it is possible to change flints without removing the whole assembly.

That, in a nutshell is how to build a BL series launcher.

Dead topic.

But to answer your questions.
A grill igniter can die after 5 shots or it can last forever. The lantern ignitor is the bedt cheap one besides a stungun. I would use a lantern ignitor. Or you can do research and find out how to use a stungun. But dont ask that here. And for godsakes
