I would love to see the same done with 7", 11" and 16" AR15's if you have not done so already. One reason I went with an AK to SBR was due to velocity being a critical part of the .223's lethality and the risk of a shorter barrel reducing effective range tremendously.

A chrono could help test the theory by measuring speeds.

Interesting stuff. I wonder what the break point is, with the popularity of going to a 14- 14.5 inch barrel and adding a permanent flash hider to keep your OAL at 16. Not sure about that 100 yard limit though, that AK Gabe was hitting with at 500 had a 12.5 inch barrel. (scratch that, it was a 5.45.)

I'm kind of impressed with the velocity from the short barrel even though there was a big drop off from the full size 16". I wonder if you went the other way and had a longer than 16" barrel... Do SKSs have longer barrels?

That was pretty interesting.

The Yugo SKS has a 20" barrel, I know because I have one. I didn't test it, but I should have thrown it in there.

It's my understanding that the 7.62x39 was optimized for the 16" barrel. You shouldn't see a 400fps increase in velocity, but I don't know because I haven't fired it over the chronograph. I'll do that next time I have the chrony out to the range.

+1 from a Draco SBR build in progress owner. Good info and thanks.

Thanks for the post. I have been wondering about the impact of the shorter Draco barrel vs a full-size AK. Since you gave a nominal effective range for the SBR of 100-125yds, did you still use a 100yd sight-in or shorten it up for your red-dot?

What about a full length 20in barrel?

 

[Titanium_Frost]

SKS has a barrel length of 20", AKs have a barrel length of 16".

 

[vitamink]

Number 2 and Number 3 are 20" barrels.

 

[Blackhawk2001]

Number 2 and Number 3 are 20" barrels.

Huh?

im assuming by yourdescriptive "huh" you can't see the picture so try this...
