Ok so a buddy of mine and i were at the range shooting my AR with the 22 conversion in. I've used this kit several times and never had an issue but had a good amount of FTF/FTE with Remington stuff but I just opened a fresh box of federal 22 bulk for this trip.

To the point, so I let my buddy have the last mag and I hear pop, pop, thrat, :confused: did I just hear a 3 round burst..? Naw because my friend didn't flinch. After he was done with the mag I asked did you pop off a 3 burst?

He said yea I thought I clicked it to burst but your gun didn't have one (yes hes a marine reason it didn't phase him)

This has never happened to me before shooting 5.56 or 22 and I have put 2k rounds of 5.56 through that rifle and about 3k of 22... This is the first time...

I know most the time when this happens the cause is the LPK. But I have shot a total of about 5k rounds and this is the first time. But why and why now and not before?

I know having this is illegal due to it being an assault weapon if this problem continues. But first time in 3 years and after 5k rounds... Should I be worried or would you guys say just stay calm and watch to see if it happens again but let it go. I shot 2 more mags after to test and see if it would happen again and it didn't so I'm a little confused on why this happened so long down the road and not before.

If your wondering it's a spikes lower with DPMS LPK I put in my self PROPERLY with a new spikes upper with a cmmg 22 kit.

Would you blame the LPK or the conversion kit or the new spikes upper?

Good info here as I have often wondered the same thing....

A few questions I have are:

- what can cause this?
- what should be look at to prevent this from happening?
- what happens if this does take place and you are at the local range?
- what can be done to avoid this type of situation?

Thanks guys!

:cheers2:

I have a Mini 30 that I sent the trigger group off for work. Came back @ 3.5# and crisp as a glass rod's snap.

My Marine friend shot it and got two doubles, but I have not for no lack of effort, been able to reproduce that.

I believe it is the way the Marines train and their trigger discipline - no complete reset, holding the slack of the two stage trigger and in the case of your and my rifles, holding it too much.

Just a thought, but I believe it is correct.

IME the kit is very mag sensitive.
Second is the hammer a notched hammer? If so the bolt can skip by without engaging. Causing a burst. ( disclaimer ) So I'm told.

That may explain an accidental bump fire of sorts (Ive done it with lighter triggers) but considering the incredibly minimal recoil of .22lr would the same still apply?
