It's pretty close, but if I had to use my BumpSAW back in Iraq, I would say it would only maybe work from defensive positions. I think if you trained on it enough, you might get it... But as I always say, if the ruskies are parachuting in over calumet, the NFA is irrelevant. View Quote View All Quotes View All Quotes Quoted:

What's the best stock to go with? I know they all ah e their advantages but from everyone here who has tried them all, what do I get? And do any had a qd strap on the stock? I believe the general consensus is the Fostech DefenAR15 is the best made... the rest are basically plastic and the same. - Clint Agreed. Looks good and well made. That being said I'll wait for the price to come down a little bit. Quick question, do you think bump stocks have a place in real world battlefield applications? I'm completely ignorant to them I admit. I've never held or shot one but my concern would be having to "float" the stock to get it to bumpfire under stress in a firefight. Also, the trigger block that's built in to the stock, seems like that would be a hindrance when shooting semi / precision shots.

Slide fire is offering the BFR for sale again.... http://www.slidefire.com/products/rifles/bfr-556a View Quote I've been staring at those for few weeks... that is a good price comparatively speaking. Unfortunately I would be in for one if they were $2500... but not $3500! - Clint |

Ya... I waited too. They were originally $6000.... I waited some more. $5500. And then I forgot about it for awhile and boom.... $3500... I purchased at 3500.

I just wish they would sell the upper/lower/BC/system. I'd pay $2k for all of that.

Quoted:
I just moved to a new state and I'm looking for a new range to shoot/test mine at. I'm running my same setup, a spikes lower with a Jard 1.5# single stage trigger on a Colt 604 upper with a Colt M16 bcg, with a DefendAR15. I've got a NiB bcg that I want to see if it will increase the rate of fire. After seeing what the light weight bcg will do I might have to order one. Thinking about trying a Geissle trigger and switching to an M4 upper. I ran a couple different M4 uppers and the rate of fire was much slower than what I could get out of my 604 upper. I've got a unknown buffer in it and think that may have been the reason. Let's keep this thing going. Geissele high speed has a 4.4 millisecond lock time (.0044 seconds), a stock trigger has about 10ms (.010s) and a JARD I believe is closer to 16ms (.016s). Considering a ROF of 900RPM, you have a cycle time of .066s. So a Geissele high speed is reaching the firing pin in about 6.66% of the cycle time. A JARD is taking about 24.25% of the cycle time to reach the firing pin. What do you recommend? And what are you using? You could probably take any trigger and use a lighter hammer spring. That's likely how JARD, or whoever, gets the pull weight down, which of course leads to a longer lock time. |

Yeah, the debadged BRO's were a good deal. I think the $99 Rise armament is pretty similar though. I might try one if I get another single stage AR trigger.

Fun fact: I have never owned a rifle in .308 in my 18 years of owning guns. I got pretty close when I found a deal on a couple FALs/L1A1s, but my friend always brought all his out and it scratched my itch. The post panic price of ammo has made that caliber even less attractive. I am kinda thinking an AK mag compatible AR would be a fun one and use the 75 round drums. |

I'm staying away from 7.62x39 for now. I'm worried about ignition problems with most of the triggers that work well in bump builds.
Perhaps an Armalite 7.62x39 two stage would solve the problem. I'll be running a bunch of ZQI 7.62x51 in my build. It's a little over $9/box. |

Went out looking for random gun stuff. The only thing BumpSAW related I found was a unbranded AR-10 buffer spring. It's objectively heavier for sure. Hopefully it isn't too stiff for TULA.
