Live Q&A - March 31, 2022

Published on April 1, 2022
Duration: 46:14

This live Q&A session from Small Arms Solutions covers a wide range of firearms and accessories. Topics include a unique Colt AR-15A2 Sporter II with a trigger set screw, discussions on popular calibers like 300 Blackout and 5.7x28mm, and reviews of new pistols like the Sig P322 and P320. The session also delves into AR-15 components such as gas blocks and barrels from Criterion and Ballistic Advantage, and explores ammunition market trends for Soviet calibers. Practical advice is offered on stripped lower receiver threads and suppressor compatibility with new rounds like 8.6 Blackout. The speakers also touch on the reliability of various firearms and offer opinions on piston vs. direct impingement systems.

Quick Summary

The 5.7x28mm cartridge is considered superior to the 4.6x30mm in terms of mass and velocity, making it a more viable option despite being marginal. The 4.6 is deemed too small for practical purposes. The Sig P320 in .380 ACP and the new Sig P322 in .22LR are also discussed, with the P322 being noted as the first Sig firearm engineered and developed in-house by Sig Sauer.

Frequently Asked Questions

What are the key differences between the Foxtrot Mike FM15 and the BRN-180?

Both the Foxtrot Mike FM15 and the BRN-180 are well-machined. The FM15 is significantly more cost-effective and features a side-folding stock, making it a strong recommendation for those prioritizing that capability. The BRN-180 offers a valve for switching between suppressed and unsuppressed shooting modes.

Is 300 Blackout a good caliber for hunting?

Yes, 300 Blackout is considered an excellent cartridge for hunting deer-sized game. It is particularly enjoyable when used in an SBR with subsonic ammunition, offering a versatile performance profile for both hunting and suppressed shooting applications.

What is the recommended gas block for an Aero M5 build?

For an Aero M5 upper with a 16-inch barrel, an Odin Rifle Works gas block is recommended over the 'Dictator' gas block. Odin Rifle Works offers a more refined design, and their gas blocks are available in various diameters to suit different barrel profiles.

Why are Noveske barrels so expensive?

Noveske barrels command a premium price primarily due to the brand name. Similar to high-end manufacturers like Knight's Armament, the 'Noveske' label itself contributes significantly to the cost, reflecting brand reputation and perceived quality.

What is the preferred action for military pistol designs?

The slide action is the preferred choice for military pistol designs due to its superior durability and reliability over alternative actions like toggle-lock systems or rotating barrels. This design has proven effective and robust for over a century of military use.
