Hello,
Years ago, I had a Colt M16 when I was on the PD, it had a 4 position selector. The burst was 2 shot. it also semi, full and safety. I have a legal 16 and I got a DPMS 4 position fire control parts in it and it runs like a top! the burst is 3 shot and I would like to change it to 2 shot. Yes, I can shoot 1, 2 ,3 or 4 shots on F/A but the 2 shot cam makes it so you don't have to think about it. I have called all the manufactures Colt, DPMS, Bushmaster,, Armalite, Brownells. so I was wondering if someone here might know a small manufacturer that produces these cams. I even tried milling off one of the lips on a cam and it would not run right. Any info will be appreciated! Thanks |

It's a rare part, but not hard to make. Call around to machine shops in your area and ask if they'll do you one as a custom job. Bring in your existing cam, and tell them it just needs 3 deep and 3 shallow notches instead of 2 deep and 4 shallow notches. Expect it to cost in $50-$100 range for a one-off, depending on the shop's hourly rates.
I made myself a 0rd burst cam for grins and giggles a few years back. Probably took close to an hour to measure up and perform all the bores and cuts.
