 4 way selector

I see some guys running a 4 way selector on their M16's.
I have a M16a1 on going through the process right now.
I would like to have the burst option, but everyone I've seen has that ugly red thing labeling the modes of operation.
Do you have to have the 'red thing' or is that just to label it?
Can you install a 4 position selector on any M16?
Where would a guy go to order one of them?
Sorry for all the newbie questions.
Thanks

Yes the red plate sits under the selector stops and the selector (which is longer) slides over it. Without the selector would hit the selector stops if pushed it. That kit is made by Tapco-DPMS and is discontinued.

Colt does make a 4 position kit but you will need to grind the selector stops off to use it. I don't know anyone that would grind the selector stops off a transferable these days just to make a Colt 4-position kit work.

The Colt kit also is the correct safe-semi-burst-auto while the Tapco-DPMS kit is safe-auto-semi-burst. With either kit the selector can be rotated 360 degrees.

Here is a pic of the Colt 4 way installed in a RDIAS equipped POF-415 modified with custom engraving and selector stops removed.



Tony will be along shortly to post his thoughts on the topic.

While the first part is not 100% correct, the second part is.

I've thought about getting the colt 4-way kit and modifying the selector with a regular semi selector, basically take the 4-way selector and cut off the tail enough so it clears the selector stops than weld cut down semi to it sticks out far enough to clear the selector stops,

Great pics guys!
Anyone who would do this mod for you?
Ya I won't be doing any grinding on my RR.
I like the idea of cutting the selector to clear the stops.
So you can just order a Colt burst kit and modify the selector to clear the stops or have it done?
Thanks

oubeta, let me tell you my experience and see if I can influence you in any way. My RR is a conversion and did not have the selector stops, so at one time I had a Colt 4-Way FCG in mine. While they were quality parts and worked flawlessly, I ended up going back to the standard FCG like 99% of the other guys who have tried the 4-Way parts. The trigger pull in semi is heavy, the burst mechansim does not reset and you are just adding complexity to your rifle. If you want to fire a 3 round burst, let off the trigger after 3 rounds. You finger is a far better burst control than any mechanical device.

If you are bound and determined to go with the Colt 4-Way, I do not know who could modifiy a selector to clear your stops. Here are some pics of the 3rd burst only parts (on the left) vs the 4-Way parts (on the right) if you want to see the differences. The Hammer w/Burst Cam and Trigger are the same between them.

The 4 position selector is always poo poo'ed. I can understand why.

With that in mind, I have an AC556 that has both burst and auto, and I use both frequently.

I agree, I would like to ease my wife into shooting FA and I thought the burst would be a perfect way to to it.

Well, first you get them comfortable and confident, shooting safely with semi-auto fire ....

Back in the day before burst was available, one technique (the one I used) was to just load two or three rounds into a mag, and let the newbie dump a few of those. When they were ready, I would start discussing trigger control, and then load five rounds and ask them to try to get on and off the trigger before all five rounds could fire. Once they were comfortable with that, we moved on to full mags.

That way, you are teaching them the proper technique –– full-auto through trigger control –– from the get-go, rather than allow them to lapse into a spray-and-pray-until-the-gun-stops-shooting mentality. And they quickly understand how important the trigger is.

I've just never been big on training wheels.

YMMV.

Don't tell me you have an AKS-74U and an RDIAS, too!

What the heck are you going to have when you get out of training?!?

If it makes you feel any better the AKS-74U is a semi.
