5 of 5 Ring steel all day long! September 26, 2020
Reviewer: Graphite Dynamics from Santa Clara, CA United States  
I decided I wanted to built a dedicated 22LR for squirrel hunting duties. I've shot conversions, and although they're fun, they're not that accurate.
I went out to my squirrel field. Part of the field has 6" steels on hangers in case hunting gets slow. Two of them are 110 and 150yds away.

After a quick dope, I was ringing the 110yd steel without trying very hard! At one point, I was double-tapping steel like it was a joke!
I then swung over to the 150yd target. I was low about an inch, so another dope of the scope, and the 150yd target was a piece of cake.

What I learned:

1. Conversion kits are fun but not very accurate (for obvious reasons). Luckily, 22 ammo is relatively cheap.
2. A dedicated barrel/bolt works like clock work! WAY better than a conversion, and almost the same price!
3. I went through 500 rounds, with ZERO FTFs, FTEs, Stovepipes or double feeds. ZERO.
4. Dedicated 22's cycle all day long, and are accurate all day long...

5 of 5 Very well packaged March 14, 2020
Reviewer: Shawn from Michigan  
Had placed an order, arrived in less than 4 days,  barrel was protected during shipping

Had placed an order with a different company,  which did not have the level of protection during shipping

Flawless finish,  next is to put this all together,  another review after the range

I do believe I will be ordering more in the future,  as I build uppers as I go

As I have read the other 2 reviews I should not be let down,

5 of 5 Great barrel and bolt group combo November 23, 2019
Reviewer: Brett Allen from Newnan, GA United States  
Very accurate barrel and the first 250 rnds no FTE or FTF.  Paired this with a freefloat handguard and 1x4.5 optic to clone my service rifle. This will be my new Appleseed rifle.

5 of 5 An impressive value August 4, 2019
Reviewer: zuk from Bay village, OH United States  
The price on this was so good that it forced me to build a 20 inch dedicated iron sight rifle.  I attached a 4x scope to test ammunition at 100 yards and found that my barrel likes Remington Subsonic and Aguila SV, making five shot groups of less than two inches once the barrel was seasoned.  My prior barrels have been CMMG branded; this RTB branded barrel held no surprises.
