    DEZ Arms Barrels- Are They Good?

    DEZ Arms offers barrels in different configurations, some made from 4140 and some from 4150 CMV. Some are chrome lined. How good are their barrels? They have a HBar Match barrel with a 5.56 chamber made from 4150 CVM. Anyone know if it's an accurate barrel? Is the quality good?

    I had a lightweight 1/9 non-CL barrel from them, for $110 I couldn't complain too much. Gas port was way too big though, .090". I ended up using it as a 22LR barrel for a while.

    I have 3 rifles built with their barrels.

    16" Fluted H-bar in 5.56
    (its at about the 4.5k mark now and still 1 moa)

    16" Heavy profile in 6.8 SPC
    It's still relatively new, only at about 400 rounds so far but it eats everything you feed it.


    20" fluted heavy barrel .. also in 5.56.
    This is rifle I drag out to irritate my friends with their $2k + varmint rifles. With Hornady 55gr. V-max ammo I get consistent sub moa groups. Average groups with this ammo are between .25 to .75.

    By the way the "overgassing" issue can be dealt with easily. Use an adjustable gasblock like the PRI or JP product. Both work fine for tuning an overgassed rifle.


    Hope this helps.

    That's what I wanted to know. What size is the gas port on your 20"? Was it too large?

    Unless I don't want an expensive and not-very-durable adjustable gas block on my rifle. I'd rather spend the difference on a better barrel that didn't have a massive gas port.

    What diameter should a rifle gas port be?

    To answer the gasport size question.... it was 0.073, which was a little undergassed for the load I use. So, I reamed it out to 0.087, which worked fine.

    A note about DEZ Arms,,, they can, upon request, custom size your gas port. Call them up and ask Sherry. Very accomodating people.


    Not very durable? What do you base THAT statement on?

    Mine's been on my 20" for over 2 1/2 yrs and better than 6k rounds! This isn't "durable"?

    Oh, and if it's "too heavy" for you .. go to the gymn! It's lighter then a lot of gas blocks on the market. And, on a bipod equipped varmint rifle weight isnt that big an issue. We don't hump our weapons 30 miles a day like we did when we were in the service.

    Heh! This barrel will be going on walkabout, so weight does matter. My goal is under 9lbs before optics. A Bushmaster Varminter w/24" bbl comes in between 8 & 9lbs and I like it

    My 20" weighs in at 11.25 lbs (used a digital scale a buddy of mine has) with it's scope and bipod attached.

    (I'm not gonna dismount my scope and pod in order to weigh it.)

    A 24" bull barrel will of course be pretty dang heavy unless you focus on weight savings somewhere.

    Skeletonized A2 stock? I suppose you could use an Ace but I personally don't care for them. YMMV

    Carbon Fiber FF Tube? I've actually considered getting one of these.

    The FF Tube I have on there now is a HEAVILY skeletonized,cheap aluminum tube from DPMS. Me, a drill and that tube! Trimmed nearly a pound off that way and didn't weaken it appreciably.

    I'm sure there are other ways to trim weight off a rifle but, these are the ones I can think of off the top of my head.

    I'm looking at a fluted barrel which should save a few ounces. I don't need lots of "rail estate" on this rifle so a few more ounces can be saved there.

    My father had a Bushmaster Varminter with a good scope and I felt it's weight was workable. Didn't weigh it on a scale though. It had no bi-pod and wasn't needed for the type of shooting & hunting it was set up for.

    I'd like to keep the complete rifle under 11lbs. Around 10 would be better and 9lbs would be an absolute delight. I've already got a heavy rifle and it's a 308.

    I'll press on with this build and see how it turns out. If there's a part I don't like, there's always the Equipment Exchange
