Unbelievable results

by -

Installed the 2.5 Primary Arms prism scope on my pistol length AR with this barrel and took it to the range today. After around 18 rounds, I was hitting steel targets at 300 and then 400 yards with a 10.5" barrel. Wow! Unbelievable results!

highly recommended

Caught this on sale and took a chance. Really nice fnish and very accurate. Looks and shoots great. I would highly recommend for a pistol build.

Pleasantly suprised

by -

This pistol build turned out excellent. Barrel is within spec, and accuracy is excellent. I did have to upgrade my extractor spring for 100% reliability. Very pleased.

Good for now.

Good product from what I can tell, not tried it on the range yet waiting for a gas block since this barrel have no holes for the pin. It would have to be a clamp on gas block or screw on at the bottom. But so far I’m happy with it. Although I wish it has a hole for the pin so I can use a standard A1/A2 front sights.

Good to go on my AR Pistol

Bought this barrel for my ar pistol as the rosco barrels were sold out so i went with the radical barrel instead. Went to zero it the other day and only took minor adjustments. Average group i got was about 1.5 inch from 5 shot groups. I will get about 3 rounds less than an inch and the other two will bring it out to 1.5inch i was also using cheap federal .223 from walmart so im sure with the right ammo youll get sub moa with a 5 round shot group. So far so good havent had any hiccups also did a mag dump to see if its running reliably. It is a little overgas not sure if its the gas block or barrel. But if youre on the fence of buying this barrel you cant go wrong for less than 90$. I would compare it to the PSA 10.5 nitride barrels as i do own one.

Fantastic Deal

I ordered this for a duty gun build and it did not disappoint. with only a non magnified red dot, i had no problems putting 5 shot groups inside a 2.5 inch circle at 100 yards. This was with a 5-6 lb trigger and shooting with no rest, just proned out at a pretty fast shot cadence for this distance with high, gusty winds. I have no doubt that this barrel would produce sub-moa performance with proper shooting conditions, trigger and optic. Barrel is a little heavy for its length, but a small price to pay for this performance and price point.

Radical FA 10.5” barrel - good to go👍🏻

I usually buy high end barrels bc I like the bullet to hit in the same place on a regular basis- usually Noveske. I bought the 10.5”- it has nothing I can complain about. For the money, it’s a good barrel. I’m a bit of a parts snob, so that’s actually saying a lot.

Awesome barrel

by -

This barrel works flawlessly. It has a great finish and is accurate.

excellent for an inexpensive barrel

by

Got to shoot a few hundred rounds through this and I was very impressed. Even with a garbage trigger (Anderson stainless trigger), 1.5" groups with a red dot at 50 yards for me, with an astigmatism, is about as good as it gets. Accuracy as good as my Ballistic Advantage 16" barrel with a better trigger.

A pleasant surprise

I decided to take a chance and get this barrel for my SBR build. It seems almost too cheap to be any good, but if it isn't, I'd only be out the $95 and shipping. No big deal.
<br>
<br>As always, shipping was quick and everything was nicely packed. I cleaned the barrel of factory debris and lube and inspected it very closely with a bore scope. The chamber is very nicely machined, the rifling lands look fantastic, as well as the rest of the rifling.
<br>
<br>This is a very good barrel and I will be purchasing another for my next SBR/pistol build.
<br>
<br>I'll be sure to update when this build is complete and I've put some rounds down range.
