Default Use of Colt HBAR II for matches?

I had bought a Colt HBAR II many years ago with the idea of using it for CMP matches. Reading the rules at the time, my understanding was that the rifles were restricted to 20 barrels. The new rules look like I could use this rifle with the 16 barrel. Is this true?

This is a video of my rifle:

Which matches are you interested in?
The modern military or Service Rifle?

Flash suppressors are not required, but if the barrel has a

are permitted. No portion of the barrel forward of the rearward location
of the gas block or front sight tenon shall have a diameter exceeding
.750”. Upper receivers and/or barrels may not be changed during the
firing of any event. Standard rifle length gas systems must be used for

One thing to consider is that it is very difficult to find a match trigger for some Colt AR type rifles - and I think you have one of those that is problematic. Colt has used both small mil spec pins (approx. 0.154" dia.) and large pins (approx. 0.169" dia.). I think you have probably got the large pins in your rifle.

I just checked and I have the .169 pins. Another unwanted wrinkle.
It looks like there are a few good if pricey options.
Ive checked and the Colt upper fits on my PSA lower with a very small amount of play. Ill test the Colt upper to see if it is accurate enough to look at getting a target trigger for it.

The Geiselle website has a page dedicated to Colt lowers and trigger compatibility.

Rickgman, I know you were really talking about the trigger pin size, and not the front take down pin size - .154 vs .170

DW, thanks! Yep I got the pin sizes wrong. I was thinking about the dimensions of the take down pins. Since Colt messed with both pins, it can get sort of confusing. I guess I should double check before posting. I fixed the mistake in my first message. Thanks again.

Actually the Colt upper has about the same play on the Colt lower.
Not exactly pleased with my Colt experience so far.
My PSA lower has no play with a PSA lower. It was almost $800 cheaper.
Hope the upper lives up to the ‘Match Target’ label.

You will also want to have a rifle with a free floating handguard to eliminate barrel bending when using a sling so that's another thing that you will want to change on the Colt HBar. You can always sell your Colt HBar II and purchase a real match grade service rifle and probably leave a lot of the drama behind.
