Our roving Brownells Gun Tech, Caleb Savant, is back to conduct another "caliber comparison" for us. This time, it's two AR-15 cartridges: the 6.5 Grendel and the 6.8 SPC (aka 6.8mm Remington SPC - "Special Purpose Cartridge"). The 6.5 Grendel has a high-ballistic coefficient .264" bullet, while the 6.8 SPC has a larger-diameter .277" bullet. Both have the same 2.26" OAL as the AR-15's standard .223 Remington / 5.56 NATO round. The big difference is the 6.5 Grendel's faster velocity and flatter
We've assembled the Triple Threat of Brownells Gun Techs - Caleb, Keith and Steve - to tell us about their favorite cartridges and handloads for them. Caleb favors the 9mm Luger (9mm Parabellum, 9x19mm) loaded with a 124 grain Federal Hydra-Shok bullet. His rifle round of choice is the 6.5 Grendel with a 123 grain Hornady SST bullet motivated by Reloder 10x. The Grendel fits the standard .223/5.56 AR-15 platform, yet outperforms 7.62x51 NATO in certain circumstances! Keith's favorites: the .300
If you thumb through the 1911 section of the Brownells catalog, you'll see a lot of references to "Series 70" and "Series 80" parts. What does that mean™ Brownells Gun Tech Caleb Savant is here to explain. A Series 80 1911 has a firing pin safety in the slide that prevents the firing pin from going forward unless the trigger is pulled. On the frame, to the right of the disconnector, there's an arm that protrudes up when you pull the trigger to release that firing pin safety. Series 70 pistols la
If you subscribe to Brownells e-mails (you DO, don't you™), you've probably heard a lot about the Brownells BRN-180™ and BRN-180S™ complete AR-15 upper receivers. Maybe you're wondering what's the difference between the two™ Caleb is here to 'splain to us the difference that "S" makes. The BRN-180™ is a carbine upper, available with a 16" or (for that extra smidge of velocity) an 18" barrel. It comes with two interchangeable pairs of piston cups, one for suppressed and the other for unsuppressed
We've all been there: we're watching an action/adventure movie involving firearms with friends or family, when one character on screen shouts, "I'm outta ammo, gimme another clip!" Whereupon, somebody in the room with you shouts back at the screen, "It's a magazine, NOT a clip!" If you're new to guns and shooting, you're probably wondering what's the difference™ We brought out the Brownells "big guns," techs Steve Ostrem and Caleb Savant, to settle that age-old question once and for all. A clip
Chassis systems have become increasingly common on rifles for PRS and other target shooting disciplines. So what is the difference between a chassis and the good ol' traditional wood rifle stock™ Brownells Gun Tech™ Caleb Savant lays it out for us. Chassis are (yep, it's spelled the same whether singular or plural!) precision machined to maintain a relationship between the barreled action and the chassis that isn't affected by humidity, flexing, or other factors that can exert pressure on the ba
Summer is here, and it's time to hit the shooting range and send some lead through targets! Aside from your gun(s) and ammo, you'll need to bring some other things. The best way to lug them to the range is in a range bag. Brownells Gun Tech™ Caleb Savant gives us his list of items a properly equipped range bag should contain:
1. Gun oil (Caleb's favorite: Rand CLP)
2. Basic gun cleaning kit ("Having it and not needing it is better than needing it and not having it.")
3. Cleaning rod
Need to upgrade the muzzle brake on your .350 Legend AR-15™ Right now, nobody sells a muzzle device specifically designated for .350 Legend, and of course, your favorite .308 / 7.62mm muzzle brake / flash hider is way too small. What's the alternative™ Brownells Gun Tech™ Caleb Savant has good news: due to the .350 Legend's .355" bullet diameter, ANY muzzle brake for an AR-15 chambered in 9mm (aka 9x19mm, 9mm Luger, 9mm Parabellum) is the right size for your .350 Legend rifle. You can get excell
Brownells Gun Tech™ Keith Ford tells us about two of his favorite guns, the Heckler & Koch MP5K and the CZ Scorpion Micro. As a bonus, he also shows us how to field strip them as he explains how each works. Both firearms started life as 9mm submachineguns and are now also available in the U.S. in semi-auto pistol form. H&K introduced the MP5K in 1976 as a shortened version of their successful MP5 subgun. It's constructed almost entirely of steel and has H&K's delayed roller lock system. (For the
Steve Ostrem and Caleb go over why the shotgun is revered as one of the most versatile firearms and go over the benefits and features on whether the platform is right for you.
Guntech Caleb Savant explains the similarities and differences of teo coldwar rifles, The VZ58 and the AKM pattern rifle. Caleb also breaks down the field stripping of each platform and how each works.
