I know what ya mean LTS, I'd much druther build one than buy one, but some people just have a hard time pumping gas, for them its better they buy. (now I'm not saying anyone that buys a custom gun can't pump gas, sometimes you get a good buy, or just don't have the time. Not everyone is mech inclined). Like my neighbor, he brought me his new lawn mower, he had added a quart too much oil in it, so I drained it for him to the proper level, I tell him to clean the spark plug, and make shure no oil is left in the cylinder, he brings me the lawn mower, and said he can't get it started, so I start to pull the plug only to find he had cross threaded, the plug and striped all the threads in the aluminium head, I pull the plug out, and look at the electrode, and it is smashed flat where he had droped it on the concrete. :rolleyes
This may be my first attempt at building a custom gun, but I do my home work.
