While I have a pretty decent thread about this over in team, I figure it’s time to bring this back to GD. Usually I just post this when peoples ask if a slide fire stock is any good, but after a couple of recent threads, I figured I'd make my own. This thread is for people who hate bump fire stocks and think are something only for mouthbreathers. Apparently it’s common knowledge to everyone except newbs and redneck yokels like myself that bump fire stocks (like the Slide Fire and Fostech stocks) are complete and utter shit. They are literally impossible to control and totally useless for anything other than a 45° cone of spray-fire. They are a toy, unlike 95% of the range-queen carbines here that are war machines and ready to go as soon as the Ruskies start dropping in over Calumet. Everyone knows that the best way to implement real machine guns like the M249 is offhand, and that the bipod on the end of it is just for looks. That's why every video you see of someone with a BF stock is some guy hosing it into a berm from the standing position. Besides, laying down prone is hard and you often get wet and dirty.... EWW! If you can't hit shit with the bump stock from the offhand position, it must be useless, right? I’m making this thread so all the diehard haters can all show me how stupid my dedicated bump fire rifle is. I'm honestly interested to hear it. There is no spring action funny business going on here. It's a plain old semi-auto M4gery retrofitted to take an M60 bipod, dissipator handguards, SD3G trigger, and a bump stock. It’s within the law in every way. Outside of maybe looks or cost of feeding it, I would say this thing is pretty legit. This is it in its most recent configuration. I think it’s actually OK looking, but that’s just me. http://i72.photobucket.com/albums/i172/schkoot/20140501_153320_zpse5hmeypi.jpg Here is my rifle on its most recent trip out. Outside of one bad primer and a light hammer strike, I'd say it ran pretty good. Still getting hits with the glare through the smoke and the sun making the target almost completely invisible. http://youtu.be/hKojiATcVNU Here it is bump firing and repeatedly hitting a Steel IPSC target from 250 yards away. Not terrible in my book. Even for a real M249, 250yds is pretty far away to keep it on a man-sized target. Turn up the sound, put it on HD and zoom in. It’s hitting. http://youtu.be/0Hrgh5txFKg So haters... Go ahead and flame away! View Quote I have to admit, that's pretty awesome. |

Yeah, I think I'm sold on one of these finally.
That Fostech stock doesn't look too bad at all. Plus I bought a whole lot of drums & mags before the ban here in CO, and I don't really have a use for the drums otherwise. |

OK, here is a quick breakdown of how I built mine. Not everything here is mandatory, but I feel like all the parts listed here contribute to the usability of the gun. Any AR-15 with 16” chrome lined carbine gas barrel. The contour on the end of the barrel matters a lot. (Price varies) Fostech Outdoors DefendAR-15 bump stock (~$500) YHM gas block—this is important if you want to use the M60 bipod (~$75) M60 bipod (~$200) Geissele SD3G trigger (~$260) Primary Arms 3X optic—found it cheap and figured I wouldn’t break the bank on something nice for a gamble project. It’s held up nicely. (~$175) Magpul rifle-length handguard. (~$40) BCM Gunfighter charging handle (~$45) Magpul BAD lever—if you don’t like it on your regular carbine, you’ll still want in on this for one-handed control. (~$30) Matech rear BUIS. (~$80) That breaks down to just over $1400 or so plus whatever rifle/mags you want to use. On the CHEAP you could do a plain SSAR-15 stock, PSA AR-15, and a different bipod for probably a bit over $1200 for everything. View Quote View All Quotes View All Quotes Quoted:

I meant to add this earlier. Regarding 22lr.
I have one i use on a 7.5 in (556) with the pig brake and a surefire 40. This thing thumps. It feels close to the blast of a m2. I also keep the stock dedicated on my m&p 15-22. The only modification i did to it is put in a jard adjustable trigger (3.lbs) i originally tuned the trigger with no pull and break like glass but it wouldn't cycle the weapon. I actually had to adjust slop in the pull (still breaks like glass) to get it to cycle. After that i had no problem and it does mag dumps time after time. Weight isn't an issue because I've had some heavy optics on it to try and bog it down. Flash suppressor is a standard birdcage A2 you don't need those fancy muzzle cones and have to grease up the stock like some people do in their videos. |

When you get an idea of what you are thinking about using, shoot me an IM. M60 bipods aren't really suited for some handguards/rails. Thry I can give you specs if you need. I barely close on my magpul stuff. |

I love my Slide Fires though I have to say the one on my AK scares the shit out of me since I can barely control it.
The 9mm slide fire with the suppressor is quite the blast though. Definitely need to start looking for a M60 bipod now.... |

And that's coming from an M16 owner, though I've never had an issue with bump stocks. Really cool friend...tempted to try this with my other rifle that has the SD3G in it When I paired the Fostech stock with the SD3G trigger I was getting insane rates of fire...and LOTS of failures. It was literally so efficient that the "bump action" was beating the BCG back into battery, causing the trigger to drop the hammer on the bolt early. Sort of a weird hammer follow. I solved it with Madcap's suggestion to put silicone grease on the moving part of the stock and slow it down. I think it might be OK with the polymer Slide Fire. H2 buffer would fix it as well, it's called carrier bounce and is pretty common in converted ar15 ' s and .22's... This thread makes me want to go take a quick video to check my cyclic rate. Posted Via AR15.Com Mobile Lighter carriers would probably help as they increase cycle speed without adding non-reciprocating mass which can then lead to bolt bounce. A slower lock time might actually be beneficial as well. This would give a few more milliseconds for the carrier to close before the hammer impacts the back of it. Another item that might help with ignition is an extended firing pin (like the 7.62x39 extended firing pins). These firing pins will stick out .010 more than a standard pin and may result in ignition (even if it's a hare earlier than a normal firing pin would). It's not much but without an auto sear it's hard to control the variables. What I would like to build is a camming trigger block (or lockout) that interfaces with the M16 carrier and only allows the trigger to be pulled when the bolt closes. This will solve the timing issues without adding an auto sear. Essentially an automatically engaging safety that clicks into place when the trigger is released then moves out of the way when the carrier closes. |

The tac-con didn't seem to have a full forced reset. I wonder if the ATF would sign off on a full forced reset. Alternatively you could use a reciprocating trigger weight. 3lb initial pull, increases to 8lb while carrier is back, drops back to 3lb when the carrier resets. This eliminates any possible binding issues that a forced cam might run into. Combine it with a short reset and it should be really fun, you could even put it on a 3 position system View Quote View All Quotes View All Quotes Quoted:

(Price varies) Fostech Outdoors DefendAR-15 bump stock (~$500) YHM gas block—this is important if you want to use the M60 bipod (~$75) M60 bipod (~$200) Geissele SD3G trigger (~$260) Primary Arms 3X optic—found it cheap and figured I wouldn’t break the bank on something nice for a gamble project. It’s held up nicely. (~$175) Magpul rifle-length handguard. (~$40) BCM Gunfighter charging handle (~$45) Magpul BAD lever—if you don’t like it on your regular carbine, you’ll still want in on this for one-handed control. (~$30) Matech rear BUIS. (~$80) That breaks down to just over $1400 or so plus whatever rifle/mags you want to use. On the CHEAP you could do a plain SSAR-15 stock, PSA AR-15, and a different bipod for probably a bit over $1200 for everything. Any reason why your using a carbine length gas system,instead of a mid length? Only because I wanted a very violent action to facilitate the bump. With the Fostech I don't think it's necessary anymore. |

Great minds think alike After the tac-con trigger debacle it made me realize the crazy amount of room in an AR lower for alternative trigger designs. I'm no engineer but I was theorizing on pen and paper with a similar sounding set up, a cam based fully mechanical trigger reset based around the hammer camming the trigger forward with an interrupter/ disconnector that kept the hammer from dropping until the bolt closed. The alternative was try to shoehorn an up-sized 1911 trigger in there. View Quote View All Quotes View All Quotes Quoted:

snip What I would like to build is a camming trigger block (or lockout) that interfaces with the M16 carrier and only allows the trigger to be pulled when the bolt closes. This will solve the timing issues without adding an auto sear. Essentially an automatically engaging safety that clicks into place when the trigger is released then moves out of the way when the carrier closes.

You need bigger magazine and longer string of rounds. Can you do a full beta magazine dump with your set up with no stoppages.
