Thinking about SBRing a Mini14. Want to get it down
to the size of a AC556. Anyone do this? If so how was
accuracy affected. Thanks in advance

I cut my stainless 80's factory folder to the ~13" barrel length of the ac556 and replaced the top of the gas block with a front sight like the ac556 had. So far it's been surprisingly accurate out to 50 yards on steel just with iron sights, although I haven't shot for groups to see what it was. I've got it paired with a dead air naked (stainless finish) nomad which looks awesome together. Many who shoot them suppressed also change our the gas block piston, to control gas, although I haven't. I figure chopping the barrel down by 3-4" and reducing the dwell time is enough.

Thanks for the response.  Been on the fence with this for some time now. Jus scored a Samson blued folder
and decided to complete this project now.
Ya no is for the pics. Looks great.
Did you cut it down to 13ā€ without the muzzle device
or is it 13ā€ including the device.

I had one that I cut back to about 13". It wasn't an SBR, it had a John Masen combo flash suppressor and front sight (the old one-piece version but without a bayo lug) permanently attached. Accuracy improved with the shorter barrel. I had it in a Butler Creek sidefolder:




A friend of mine SBR’d one of his, but I never asked him about accuracy before or after:

I did one - Did the work myself and it shoots great.  As it was a GB with pencil barrel I think there is less whip, but with the SBR and Ruger sights, its not a match rifle.

You can read about it on this old thread.

Cherenkov, I appreciate the link. You did a great job on it.
Tracking shows that my blued Samson folder should arrive this Sunday.
I already had my barrel cut down to 16ā€ with a SureFire suppressor adapter pinned on.
I’m going to still want to cut it down a little more to 13ā€.  I will try and get a pic up
of it in the Samson when it arrives.
