The screw in pins can be swaped easily with a standard push pin and detent. I swapped mine out. The pins that are different are the fire control pins. Hammer trigger are .176 vs .155 for mil spec.

I'm confuse by all of Colt's nonstandard crap too.

Off the top of my head for various models:

unchromed bores
plastic buffers
.311 pivot pins
oversized fire control pins
nuetered bayo lugs
sear blocks
plastic trap doors

Colts have had standard sized pushpins since at least the mid-90s, maybe around 90 with the white label guns.  The fire control pins are oversized. I've never seen a Colt woth a non-chrome bore except for that 1 with the 24" stainless barrel.

Get the Colt, you'll never regret it!

The 6450, 6520, 6721 and 6920 all use the large hammer/trigger pins.

What is the problem with the front screw pin on the Colt?  In a fire fight with your weapon broken down(folded in half)would you want your troops to have have there uppers seperated from the lower?  That would put much more pressure to get the weapon back together under fire!

Broken in half is the best way for a combat weapon to be!!  Kind of like a FAL (yep it has a screw)also!

You guys that bash Colt for the front take-down screw have no idea of why it is there!

KISS   you don't need to take your rifle into!

Wow!!  I guess I feel better about my SP1 with its large screw pivot and standard sized hammer and trigger pins. Not that I fealt bad about it in the first place.....  

And for more confusion, not all screw type pivots are the big size. I have an early 1990's R6830 (7.62x39) that has a screw pivot, but it's standard M16 diameter. Replacing the pivot with a standard M16 pivot pin was a no-brainer. I kept the screw of course - no telling what some eclectic collector might value some day.

They made rifles with standard diameter screw type pivot pins, but they made a whole bunch with a larger pivot pin diameter, thus the adapter kits that are on the market.

Just a slight correction -- the large pins are .170".

The LE guns have the standard front and rear pushpins but ( as was noted ) use the large ( .170 ) fire control group pins ).....hey....bigger is tougher...right?

Why would anyone want to clean their rifle during a firefight? Ifyou have a stoppage that would require opening the rifle up, then by all means just push out the take down pin & pivot it open. Having a standard front pivot pin pin does not obligate you to use it to separate the 2 halves, It just gives you the option & convenience of doing so.

The take down screw on Colts is for civilian models & is an attempt to make it harder for a civilian to place an M16 upper on their semi lower.The uppers on semi guns have no clearance cut for the auto sear.

What do you not need to take your rifle into? Or did you mean to say "in two"? The word two meaning the #2, in turn meaning 2 separate pieces
