#Uppers

The .17HMR is one of my favorite rimfire calibers. The hot 17 caliber rimfire cartridge is both supremely accurate, and light recoiling making it a good step up from .22LR in terms of both inherent accuracy and range. Bear Creek Arsenal is following up the success of their .22WMR AR-15 upper with the release of the new BC-15 17HMR Billet Upper Receiver to give rimfire enthusiasts access to yet another popular rimfire cartridge that they can plink, hunt, or target shoot with by simply slapping it on an AR-15 lower receiver.

Hello and welcome back to another edition of The Rimfire Report! This ongoing series is all about the rimfire firearm world and its various guns, ammunition, gear, and sports! 22 Winchester Magnum Rimfire (.22WMR) is a very popular cartridge although maybe not quite as popular as its tiny little sibling the much-venerated .22LR. While .22WMR is great for things like extended range rimfire target shooting or varmint hunting, the cartridge has seen very little attention in the way of semi-automatic firearms outside of a few notable examples like the English-made Guncraft AR-15 or the Savage A22 Magnum rifles. A couple of weeks back Bear Creek Arsenal announced the introduction of their own offering to the field in the way of a complete .22WMR upper for the AR-15 platform. I was fortunate to receive a copy of it for testing and evaluation purposes and today on The Rimfire Report we’ll be running my copy of the BCA 22WMR upper through a series of tests to determine how well it performs as configured out of the box.

In this episode of TFBTV‘s #GunFest2021 coverage, James Reeves speaks with Joe of LMT about new LMT rifles, uppers and a new 2-stage trigger all being introduced by Lewis Machine & Tool for 2021.

Having worked on antique firearms in the past, I really appreciate the modularity and ease of repair that modern firearms have.  This is especially true in the case of the AR-15 platform.  That being said, quality parts are needed when making repairs or modifications.  Though I come from a gunsmithing background, I  was not aware just how many high-quality AR-15 parts DSArms makes in-house nowadays.  Better known for being masters of the FAL-platform, DSArms is no newcomer to the AR-15 game.  When I had need of a duty rifle, the first AR-15 I ever purchased over a decade ago was a DSA ZM4 that featured a DSArms-made lower mated to a 1st-generation POF-USA piston upper.  When I learned I would be testing some of DSArms’ parts and tools, I assumed there would be 3 or 4 parts in the box. To my surprise, I opened it up to find a smorgasbord of 34 parts plus 2 different versions of their combination axe/AR-15 armorer’s tool!

Aero Precision has been teasing their new “Enhanced” AR-15 upper receiver and companion rail kits. Designed to be used in conjunction with one another, the two parts promise customization, ease of mounting, and performance. The handguards index to the receiver and are free-floated. The system is proprietary and uses a unique barrel nut.

Bushmaster is now offering an upper for the .300 BLACKOUT (aka 300 BLK or 300 AAC BLACKOUT) cartridge.  The uppers use a light contour barrel with a black Melonite coating.  Barrel length is 16″.
