What effect if I cut off four inches of barrel length?
There are a couple of rifles that I am looking at for my next purchase. They have 20 inch barrels. I'd prefer that they had 16 inch barrels to make them a bit more maneuverable and easier to pack around. Generally, what is the effect and cost of having a gunsmith cut off 3.5 to 4 inches of barrel length from a rifle? One of the rifles is .223 and the other is 22 magnum. Thanks for any information!

The cost depends on what type of rifle.

And for others it would leave them with 26".

Personally I also like the shorter more maneuverable barrel.
And if you do cut them down I wouldn't be concerned about the loss of velocity but I would be concerned with their loss of value at resale, if you ever need to sell them. Is also the possibility of cutting the barrels affecting their accuracy if it is not done correctly. |

For most .223 loads consider an 18.5" barrel length, it's close to the max velocity provided by a 20" and is a good compromise.
Shorter than that and it starts losing about 100 fps per inch. As far as .22 winmag I'm not sure, I researched .17 HMR because I bought one, and 19-20 inches seemed to be the top length, but I went with a 24" for the iron sight radius and have had higher velocities with CCI A17 and Remington Premium Rimfire Magnum than my friend does in his 20" barrel. Other loads he is actually slightly faster. |

I would assume velocity.

Here you go OP -- check out the following article where they cut a barrel down from 26" to 6" and provide data:

As long as its cut down properly. There's a reason match barrels are crowned. The last thing the bullet touches is the tip of the barrel. A burr at the muzzle would send accuracy to crap. And why cleaning a barrel from the muzzle end should always be done carefully if it can't be avoided.

That said, I can't help frowning on the crowd that cut AR barrels to 14.5", and then permanently attach a flash hider to meet the minimum legal barrel length. This seems like style over substance, unless actual CQB is involved. Then again, as long as it is safe and legal, why should you and I care what someone else wants to do to their rifle; or why? Advising them on technical factors, such as the potential for a "rifle length" gas system on a 20" AR not working reliably, after the barrel is cut to 16" is all the help that should be offered. |
