Today is really two reports in one. I’m covering the new UTG 4-16 AO Compact scope and this is also the fifth report on the FX-Dreamlite precharged pneumatic air rifle. I’m glad I got back to it because I found a second good pellet for the rifle today. But first the scope.

Mounting the scope

Because the FX Dreamlite is such a drooper I tried to use the Sportsmatch 30mm high adjustable scope mounts. The would have been ideal, but they don’t work because of the FX 21-shot magazine that sticks up so high above the top of the receiver. I ended up using the True Strength mounts that came with the UTG scope and I shimmed under the scope on the rear ring. The scope barely fit so the magazine can be installed. And yes, I am aware there is a Mini FX 10-shot rotary magazine available. I just don’t have one. But that’s what this rifle needs.

The 21-shot magazine just clears the scope. A 10-shot Mini Mag would be better.


This UTG scope comes with a separate sunscreen that screws into the objective end of the scope. It’s three inches long, so it provides good protection from the sun. If you have never experienced it, when the sunlight falls on the objective lens it flares up as a bright spot that ruins your aim. You loose the reticle and sometimes even the target when this happens. But this new scope has you covered.

Clear, clear, clear!

Sight-in started at 12 feet and then moved to 10 meters. When I got back to the shooting distance of 25 yards I got the scope fully adjusted and the image was crystal clear. I could not see the thin black crosshair over the bull, so I turned on the illumination — exactly as I did with the Meopta Optika6! Then it was clear as a bell and I could also see the 10-dot of the bull. This scope is as clear and sharp as I told you yesterday. Now I’m going to switch to the report on the rifle, but I have more to say about the scope as we go.

First target

I sighted-in with 8.44-grain JSB Exacts that so far were the most accurate pellets for this rifle. So, the first target was a group of 10 of them. The group measures 0.454-inches between centers. It’s higher than the center of the bull to preserve my aim point. It’s also a little left of center.

The first 25-yard group of JSB Exact 8.44-grain pellets measures 0.454-inches between centers.

Target two

I adjusted the scope several clicks to the right and several clicks down and shot the second group with the same pellet. This time 10 JSB 8.44-grain pellets went into 0.388-inches at 25 yards. This group is also rounder than the last. I think I was getting into the groove. The FX trigger is light and crisp, but I shoot so many airguns that I forget how each one likes to be held and shot, and it takes some time to remember them. The Dreamlite holds steady and the trigger is superb!

This 25-yard group of JSB 8.44-grain domes measures 0.388-inches between centers.

I would also like to point out that this UTG scope is displaying absolutely no stiction. When the adjustments are made the pellets go to the new location on the first shot. That is something I seldom see in a scope test. It usually takes one or two shots to jiggle the erector tube to the new setting.

JSB Beasts

I tried the JSB Beast pellet again. This time they were all over the place and only 4 of 5 hit the target paper. They measure 2.215-inches between centers, but without shot 5 they aren’t a real group. I quit this pellet after 5 shots.

Crosman Premier Lights give strange group(s)!

Next I tried some 7.9-grain Crosman Premier lights. Would their harder lead be better in the Smooth Twist II barrel? I only loaded 5 pellets after seeing what the JSB Beasts had done.
The first 5 Premiers went into 0.371-inches. Huzzah! Had I finally found the second good pellet for the Dreamlite? I do note that these pellets shifted off to the left on their own. The scope adjustments were not touched.

I then loaded a second five Premier Lights to complete the 10-shot group. The first shot hit the target paper an inch to the left of the last group. Huh? I had not changed a thing — and for those wondering about the barrel stability, I had not bumped the barrel when I reloaded.

These 5 Premier Lights went into an IDENTICAL 0.371-inch group whose center is about nine-tenths of an inch to the left of the first 5 shots. This is the strangest group I have ever seen and I wouldn’t believe it if I had not been there to see it! Obviously something is up, but I don’t have much to go on yet. I checked the air pressure in the reservoir and it was sitting around 180 bar at this point. That should be good. The 10 shots measure 1.158-inches between centers.

Twin 0.371-inch groups of Crosman Premier Lights are 0.9-inches apart at 25 yards. The entire groups measures 1.158-inches between centers. I have no idea what happened, but I’m pretty sure it wasn’t the pellet.

Crosman Premier Heavy

The last pellet I tested was the 10.5-grain Crosman Premier Heavy. Because of the previous strange double group I refilled the FX to 250 bar. I know from all the testing that’s been done that the regulator is working well in this rifle and I can trust it when it’s full.
I loaded 5 pellets and shot at the bull on the left of the paper. The first pellet barely nicked the left edge of the target paper. I shot the other 4 and got what appeared to be a tight little group that was right on the edge of the paper, but the pellet shift was noteworthy — very similar to that of the Premier Light.

Second attempt

I cranked a lot of right adjustment into the scope and shot a second group. This time 10 pellets were loaded into the mag. And, shot after shot, they kept going to the same place! After the fifth pellet I couldn’t see the hole grow any larger. Ten Premier Heavys went into 0.353-inches at 25 yards. Folks, we have a winner! This is the second pellet that the Smooth Twist barrel likes.

Summary for the UTG scope

The UTG Scope is everything I thought it would be. It’s clear, the reticle is very useful, the illumination works great (yes, I turned it off after shooting!), the mounts work great and the scope has zero stiction. The only concern is that this is a compact scope, so there are fewer placement options when mounting. Should you get one? Only if you are looking for a superlative small scope that won’t break the bank!

Summary for the FX Dreamlight

I am so glad I did today’s test. The Dreamlite is still sensitive to what pellets are used, but it now likes at least two.

The issue of the double group of Premier Lights needs to be investigated. I won’t tell you what I suspect so you can discuss it without any bias. But I do plan to test the rifle again to see if I am right.

If I hadn’t done this test I would have written the Dreamlite off, and that would have been unfortunate because there is a lot of innovation here. This rifle needs to be played with to sort things out as our friends in the UK would say. But there is a worthy air rifle here. It reminds me of my TalonSS with so many features and adjustments that it takes real dedication to get to know it. But the journey is worth the effort.
