A friend of mine bought one of the slidefire stocks a few weeks ago and brought it out for me to try it out and see how “awesome” it is. The first thing I noticed was how huge and bulky it is.
Not only is it kinda big and bulky, but it makes using the safety pretty difficult. that is a pretty big turn off to me. The cheek weld is not bad at all. The problem wit this is that it does not matter because the gun can not be fired accurately. Sure the youtube videos make it look like you can do controlled bursts and keep the rounds on target the truth is you can not. You can make controlled bursts ( when it works) but the method used to make the stock do its trick, makes shooting with any kind of effective fire pointless.
The author trying to make it work with his 6940 upper installed. And still failing like most things in life he tries.
The way this contraption works is you lay your finger across the trigger very loose. The finger actually rests on a ledge and barely touches the trigger. You then pull forward on the forearm and this simply is suppose to cause a controlled bump fire. I know it sounds odd and it takes a bit to get the hang of it.
The lower used was a Stag arms ( not mine!!!) on top of a RRA carbine upper. ( not mine!!) The lower had a carbine buffer in it instead of a H or H2 buffer. This combo worked right up until it did not. I still have not figured out the problem is but the gun would just stop. The trigger was stiff, not much and not loose like just fired. A round would be chambered with a normal dimple on the primer but thats it. Sometimes on ejecting th4 chambered round, I found it to be bent slightly at the shoulder neck junction. Odd.
I do not think the slidfire is worth the money. Maybe if it was 100 bucks but even then I really would not care to have one. Maybe on a semi auto RPK clone with bipods and a 100 round drum it could be fun. But I doubt it.
The problem could be from bolt bounce or the timing but I do not know. it was not my gun and I did not and could not have taken it all apart to find out or try it more. So I am sorry to say I can not give any solid answers about it. So solly cholly.
I was told this model was the 2nd gen model that sold for around 360 bucks. I keep thinking tat would have bought 3 surefire 60 round mags or a case of ammo. So unless you are a dirt clod blaster or so rich you just do not care. I would pass on this contraption.
