Test fired 2nd AR-15
Stopped by the local gun shop yesterday, they had 24 AR-15 stripped lowers for $150 total, including taxes, so I bought one. Picked it up today after my waiting period, put enough parts in to get it ready to fire. I used the same upper I used on my DIY lower. Fired fine, no issues. A friend was telling me about a guy they shot with that could stiff arm a semi-auto and pull the gun against his finger and bump fire but without a bump fire stock. So I tried it, after a few failed attempts I got it to double, then I got a 3 round burst. Sounds like a machine gun and I can hit the ground with every shot! :-) I don't think it would be a good way to hit anything, may be useful for gardening, I can plant seeds in the holes I shot in the ground. After I torque the barrel on the M-16 upper it will be ready to test fire. The 4 raw forgings I ordered in early February finally came in today. I figure I'll try to machine them with my CNC mill to the 80% point so I can sell if I want or finish the trigger pocket in the CNC when I decide to. I wanting to build a 30 cal for the 300blk cartridge, that will probably be my 3rd upper but I hear ammo is hard to get for the 300blk. Maybe I can get some dies to neck out 223 to 300blk and load my own. RogerN |

Test fired 2nd AR-15
Anyone seen these slide fire stocks? I saw some on youtube videos, also
Cabelas has them and there is a video. They pretty much make a semi-auto fire about like full auto and according to BATF per Cabelas, they aren't illegal. So on one of the videos, a guy fires 29 .223's at a human size target, gets all rounds in the black. So it fires like a machine gun, it's legal, and it allows for control. Bad thing is it doesn't appear to be worth $350 but I searched and see people are making their own. They take an ordinary adjustable stock and attach the pistol grip handle to it then a rest to hold your finger on, pull the gun so the trigger hits your finger hard enough to fire, the recoil causes the trigger to reset and continued pull on grip and pressure on trigger makes it fire pretty much like a machine gun. I heard that an actual machine gun fires faster. Sounds like an interesting project, modify a stock and attach a pistol grip and a finger rest. RogerN |

Somewhere there is a youtube film of a guy firing a M-16/15 with no add on gizmos. Just letting the gun recoil against his finger on the trigger. It didn't fire as fast as the AR-15's the A.F. had but it certainly was cheaper than the add on. Bad thing is it doesn't appear to be worth $350 but I searched and see people are making their own.

Test fired 2nd AR-15
This week I received the parts kit, less stripped lower, that I ordered 2/4/13, website said it would be at least 4 weeks, LOL. I put the new upper on my 2nd lower and test fired it yesterday, all went well. Jammed several times at first, kind of stiff. I still haven't assembled my M-16 upper, just have to torque the barrel and pin the gas tube, haven't bolted my vise down yet. I'd like to make a homemade slide fire stock sometime. We've been shooting and then locating the brass with a metal detector, getting about time to run the progressive press for an hour or so. RogerN |

We've been shooting and then locating the brass with a metal detector, getting about time to run the progressive press for an hour or so. The design of the ejector is a bit overkill in the AR-15. You can tone it down a bit without any drop in reliability. Competitive shooters do this all the time so they don't lose too much of their match brass. This has to be done in conjunction with the extractor. If you have a stiff extractor spring with an added o-ring, the ejector has to be strong enough to overcome that, and it will throw the stuff all over. I set up two "spacegun" AR's for competition that would dump all the brass about 2 feet to the right & front of the shooter. I never had a jam, with over a thousand rounds through each. My wife and I shoot offhand matches pretty much exclusively, and we now don't shoot with an ejector at all. It's all single shot with enough time to fish the case out & put it back in the box. As long as you remember to grab it after you've scoped & recorded each shot, you don't burn your fingers. Doug White |

You pull the bolt back yourself or something to eject the case? You got me curious. I had a Ruger Mini 14 and thought about modifying it somehow to disable the gas port and then just manually cycle the bolt to eject/re-chamber the next round. Some sort of a switch so you could go back and forth between semi-auto/manual mode. This was way before the internet is what it is today so I haven't actually went searching for info either... -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

The 14 is easy to convert. Basically you add a needle valve to the front of the gas block. It allows you to dial down or shut off the gas flow. I did it with mine (before it fell overboard) to tame the action. Folks at the range didn't like getting hit with brass 6 lanes away... The AR can be modded the same way, or for most folks they just remove the gas tube and block the port or use a blank barrel. I never understood the conversion to single simply because you could start with a good bolt gun and get better results with less work. But everyone has different tastes. -- Steve W. |

Some sort of a switch so you could go back and forth between semi-auto/manual mode. This was way before the internet is what it is today so I haven't actually went searching for info either... The spaceguns have a bolt handle screwed into the side of the bolt carrier, and there is a slot milled in the upper receiver to clear it. You could use the charging handle on a regular AR to get it rolling, but after that, the bolt should lock open after each shot. The side bolt arrangement is needed if you have an adjustmable cheekpiece, because the charging handle typically won't clear the cheekpiece if it's at a good height for most shooting. Here's a photo of the two rifles I built: http://users.rcn.com/gwhite/Misc/SpacegunsSm.jpg There are special single round followers that you can put into the magazines so you just drop a round in and close the bolt to load. http://www.fulton-armory.com/magazin...ingleloadsnap- inplastic.aspx This model just snaps in on top of a regular follower, and you don't have to take the magazine apart.

Many self loading rifles have adjustable gas ports that one can open wide to smaller and smaller and totally closed with a simple adjustment. My 1950s FN-49 can be turned off in 2 seconds with the rim of a cartridge case. The later FN-FALs are the same. Repeat and rinse. -- "You guess the truth hurts? Really? "Hurt" aint the word.

Nope, no bag of worms at all as long as you don't put a shoulder stock on them. If you're building your own custom short pistol buffer that makes it pretty clear a standard shoulder stock isn't going on it. No vertical grips on the front either, so ideally use a style of handguard that doesn't lend itself to that, like a basic round one vs. a quad rail. |

Careful not to cross the alphabet boys here. You can't convert a rifle into a pistol. You have to start with areceiver that was never on a rifle. Don't know if the rule is activiely enforced, but it is there. FWIW, I think the AK makes a better pistol, no large buffer tube sticking back. real cheap build too. Karl |

Karl http://wpnet.us/red_devil_small_right.jpg Built from a forging, short pistol buffer, no way to readily attach a conventional shoulder stock, no way to readily attach an off the shelf front vertical grip. Also pretty clearly built as a unit given the unique color. |
