Jon from United States, GA Public Profile

Installed into two 10/22s: one relatively newer rifle that came with a composite trigger housing, and another from the 1990’s. Both had loose factory pins. The TandemCross pins required a light tap to fit even before inserting the pin deeply enough for the ball to make contact.

The newer 10/22 required more tapping force to push the pins into place.

This scope is clear, very easy to use, and is not too heavy. I put it on a 300BLK AR15, zeroed at 100yards. The reticle trajectory compensation hack marks are in meaningful spots for both my supersonic and subsonic loads. Bushnell’s online tools print an accurate range card for any load and reticle combination.

This is not a scope that is designed to have its turrets twisted on a regular basis. They are steel turrets that have a coin slot to ease turning them; without the coin, they are not easy to adjust-not impossible. This scope is best used with the reticle holdovers for range adjustments. They work well for me. Well enough that I ordered a second one of these scopes.

If you want a scope in the same price range that can be dialed easily, look at the Burris E-1 scopes. I think either model will easily get you out to 600yards with an appropriate caliber-pretty nice for under $250.

Mine is being used on a 30/30 Lever Action. 4x is all the magnification that is needed on a 200yard gun—-in my opinion. It is another “set it and forget it” Leupold. The glass seems clear and well filtered.

This is a good looking and very functional product. It is a simple tube design with no accommodations for adding rails or accessories. It feels great in my hand, just the right texture and diameter for me.

Installation is easy to understand, but very difficult to preform without some frustration. The included barrel nut tool is worthless, at least I could not get it to work. The only tool that works is one that applies friction around the barrel nut’s round exterior. A “strap wrench” is suggested by many U-Tubers and review writers. I ended up using duct tape wrapped around the nut and a piece of belt leather to protect its finish, and a set of very large channel lock pliers located so as to only provide contact force over the solid portion of the nut right around the receiver threads, not near the threads for the rest of the free float tube. Positioning the pliers was cumbersome while the upper was locked into a vice block, but everything went well and the nut was properly timed and torqued without marring the finish.

Final note on the barrel nut:
Its torque is not measured, as it is not possible to attach a torque wrench. But, it is believed that if you hand tighten the nut and then twist it down far enough with a strap wrench to line up the next gas tube hole, it will have proper torque applied.

I used barrel shims to reduce the amount of torque required to line up the holes. This was necessary because my holes lined up perfectly when only hand tightened, and I felt lik

The tube installed as expected, no burrs in the pin hole, all bend angles were correct, the tube seems well made. I bought this tube because it carries the CMMG name, and I believe CMMG to be a good source of quality parts at a fair price.

I can find nothing wrong or lacking in this gas block.
I like the “clamp on” feature, and particularly like the angle of the attachment screws. The block is very small and easy to work around when installing a free float hand guard.

I am using it on a 300BLK carbine length system, and Trybe Defense barrel. The upper is intended to be used for hunting, and plinking.

If building a self defense type gun, I would not use this gas block for fear of it coming loose at a critical time. For a defensive weapon, I would use a mil-spec pinned gas block.

I have only test fired one round. So, I cannot comment on accuracy. What I can say is the barrel arrived in good condition with thread protectors installed on each end, and the finish, threads, and feed ramps look very well done.

The only issue noted is related to the receiver made by Aero that I am using. The barrel extension ramp cuts overhang the Aero Receiver Ramp cuts by a small amount. I have seen this issue mentioned in two other reviews, and can confirm it is a possible problem. However, after testing the feed of my preferred bullets from a Magpull magazine, I have noted that the bullet tip does not impact the combined ramp surface below the barrel’s ramp. So, it seems to be a non issue. This issue may actually be an issue with the receiver and not the barrel—-I do not know.

I will update this review if any remarkable accuracy (good or bad) is noted, once the entire build is completed.
