The video discusses the accuracy and point of impact shift of the Sig Spear LT rifle, focusing on whether its barrel flexes under force. Initial tests show disappointing accuracy but provide a controlled data set for analysis. Applying force to the barrel in various directions reveals that significant flexing can cause shifts in the point of impact, although the rifle tends to realign after the first shot. Comparisons are made with a Geissele URGI rifle, which exhibits minimal deviation under similar conditions. Testing with a suppressor attached shows negligible impact shift. The findings highlight practical concerns about barrel flex, especially in real-world scenarios, concluding that while the Sig Spear LT rifle has smooth shooting performance, it faces challenges in accuracy compared to premium rifles like the URGI, HK416, and SCAR 16. Future videos are promised for further practical accuracy tests.

In this part of the video, the narrator discusses testing the accuracy of the Sig Spear LT rifle and whether its barrel flexes under force, causing a point of impact shift. The segment begins with an acknowledgment that the video will focus largely on data analysis of paper groupings shot at 100 yards, rather than showcasing dynamic shooting action. It mentions that previous posts by T-Rex Arms showed potential flex between the barrel and handguard, sparking widespread online debate. This video aims to provide a more conclusive test by shooting the rifle under controlled conditions to observe any point of impact shifts. The narrator explains that they will be conducting a nine-shot group test to see if applying force to the barrel affects its accuracy.

In this part of the video, the focus is on testing the rifle’s accuracy under various forms of stress. Initially, the rifle’s accuracy is assessed with a 2.9-inch or 2.4-inch group size, which was disappointing. Further tests are done by applying force to the barrel to the right and shooting another nine-shot group where the first shot lands right, but the rest align with the control group, resulting in a 3.08-inch or 2.44-inch grouping with a tighter 1.25-inch cluster.
Next, by flexing the barrel to the left and shooting again, the first shot shifts left with a 2.05-inch group or a 1.7-inch grouping, which is closer to the expected performance. Finally, a test while pulling the barrel and handguard out of alignment showed that the Arisaka zero retention clamp improves alignment, leading to an improved shooting performance.

In this segment of the video, the speaker reviews the results of a shooting test, noting no obvious outliers in a two-in-five shot group, consistent with the control group and previous tests. While reviewing footage, concerns arose about the two furthest-out shots, prompting speculation that the barrel might be flexing off-center. After a sponsor message from Midway USA highlighting their extensive range of shooting products and efficient shipping, additional testing was conducted. The new test results showed a nine-shot group with a 2.41-inch grouping, including an expected solid center cluster with one flyer, suggesting the rifle might need more use to achieve optimal performance.

In this segment of the video, the group tested the impact shift and grouping pattern with a suppressor attached. They found that the grouping size remained similar to the control, with only a negligible point of impact shift, perhaps rising by half an inch. Next, they conducted a flex test by flexing the barrel to the left while shooting to see if there was an impact shift on the first round post-flex. Surprisingly, the shots did not land where expected; instead, they landed right then significantly left. When multiple shots were fired, the rounds returned to the original grouping position. This indicated that applying significant pressure to the barrel results in noticeable flexing, which aligns with their testing observations.

In this part of the video, the speaker discusses the impact of flex pressure on a rifle’s point of impact shift, noting measurements between 0.5 to 3.5 MOA. They argue that while the test might seem extreme, it mimics real-world scenarios like a fall with full gear that could flex the barrel against the receiver. They compare this with a controlled test using a Geissele URGI 14.5-inch barrel rifle, which showed minimal deviation in impact when subjected to the same conditions. The speaker clarifies that although their findings aren’t conclusive, they were thorough in their testing methods. Despite potential variables, their results showed significant differences between the two rifles. They plan to share further practical accuracy tests in a future video.

In this part of the video, the speaker evaluates a rifle, noting that despite wider groupings compared to premium ARs, it delivers smooth shooting and controllable performance. It demonstrates practical accuracy within combat scenarios, though concerns about barrel flex arise when compared to competitors like the URGI, HK416, and SCAR 16. The speaker concludes by acknowledging these red flags from a consumer perspective.
