Duration: 16:58

This video provides a comprehensive review of the SIG Sauer Spear LT, specifically a 16-inch conversion kit that adapts an AR-15 lower receiver. The reviewer tests its reliability over 500 rounds, examines its adjustable gas block for suppressor use, and compares it to the PSA Jackal. Key features like the dual-spring recoil system, rear charging handle, and included Romeo 4XT Pro optic are discussed, along with potential drawbacks such as the charging handle quality and the gas system's tendency to be over-gassed.

Quick Summary

The SIG Sauer Spear LT is considered reliable after a 500-round test, with no malfunctions observed. It features a two-position adjustable gas block ('plus' for more gas, 'minus' for less) designed for over-gassing to ensure functionality with various ammunition types, especially when suppressed. A key operational note is that the bolt will not lock back when the stock is folded due to interference with the AR-15 lower's bolt release.

Frequently Asked Questions

Is the SIG Sauer Spear LT reliable?

Yes, the SIG Sauer Spear LT demonstrated reliability over a 500-round test with no malfunctions. Its design prioritizes reliability, even if it means being 'over-gassed' to ensure it cycles with a wide variety of ammunition.

What are the settings on the SIG Spear LT's adjustable gas block?

The SIG Spear LT features a two-position adjustable gas block with a 'plus' setting for increased gas flow, useful for adverse conditions or weaker ammunition, and a 'minus' setting for reduced gas flow, which is optimal for suppressed shooting and smoother operation.

Can you shoot the SIG Spear LT with the stock folded?

Yes, you can shoot the SIG Spear LT with the stock folded. However, a notable operational quirk is that the bolt will not lock back on the last round when the stock is folded, as it interferes with the AR-15 lower's bolt release mechanism.

What are the main differences between the SIG Spear LT and the PSA Jackal?

The PSA Jackal uses an AK-like operating system with a rear recoil spring and connected bolt, while the Spear LT retains an AR-15-style bolt with a dual-spring recoil assembly. The Jackal also offers a more granular 8-setting adjustable gas block compared to the Spear LT's 2-setting system.
