Blockader from United States, GA Public Profile

This review is for the 18" rifle length gas 3-gun profile Odin Works barrel in .223 wylde. It is stellar. Fit and finish was excellent and it is well balanced counter weighted by a Magpul UBR gen 2 out back. It balances right at the front take down pin. I used the Superlative Arms adjustable gas block with this barrel along with a lightweight BCG, VG6 Epsilon comp/brake, and Tubb flatwire spring resulting in an overall impulse that is very soft and flat. Best of all I have been very surprised by this barrel's accuracy. I do not reload 5.56 Nato, but I have a variety of bulk and surplus ammo all of which I have tested through this build at 100 yards from sandbags. 5 shot groups of various M855 and M193 consistently give results right around 1.5 MOA. The one it liked best, Lake City M193 from the 420 round cans gets close to 1 MOA. Its also likes 45 grain frangibles especially well, much to my surprise. Match ammo or handloads would certainly be better, especially out past 300 yards or so. I am very pleased with the barrel, its worth its weight in plundered silver.

I use these even on lowers with tensioning screws as they provide the snuggest fit possible. The CMMG seem about as good as any of the other brands I have tried, maybe a bit softer. Whether thats good or bad just depends. Any fitment problems can be solved by trimming with a sharp knife.

This unit performs well for most operations you need on an AR build, especially if you have a heavy duty adjustable vise to mount it in. The only thing I have found thus far that it fails at is in holding a barrel upside down to drill and pin a muzzle device to a 14.5" barrel. There are other inexpensive options to accomplish that though.

Having run my 16" bbl AR9 build with just a thread protector on the muzzle for a few months I was finding it difficult to keep double taps on a 66% IDPA plate at 50+ yards. Though I figured the forces from the blowback action were the main contributor to the weapon movement I figured it was worth a shot to try a comp/brake. There are not a ton of options in 1/2x36 thread and there are not many reviews for the ones that are available (at least pertaining to 9mm), but the YHM slant brake seemed fairly aggressive and was on the less expensive side so it won my money.

I ran the PCC bare muzzle for a few mags and then installed the slant brake for a few more. The ammo used was 115gr FMJ of the "plinking" variety. I also removed ear pro for a few rounds each to evaluate noise increase and did a concussion "test" with an empty beer can placed on a table 4" to the right of the muzzle.

With bare muzzle at 25 yards my double taps were mostly within a 6" circle on the steel plate. I could not reliably put the second shot of a double tap on the plate at 50 yards. The beer can did not even wriggle when the weapon was fired with the muzzle 4" away.

After field installing (my home range is in a field) the YHM slant brake the improvement was immediately obvious. My 25 yard double taps were all within 3" of each other, with some much closer. Most of my 50 yards double taps successfully landed. Recoil was somewhat reduced (still action movement present of course) and the muzzle remained sig

Purchased this for a dedicated .22lr build to be my daughter's training rifle. It is compact and very light but seems plenty strong. Barrel nut was not milspec wrench compatible, so keep that in mind, I used a regular crescent wrench on the flats.
