by David Crane david@defensereview.com DefRev (DefenseReview.com for any newbies out there) has known about the RROC Conversion for quite some time–about the last year and a half, long before it even had a name. RROC stands for Reduced Recoil Operation Control system, and it was invented/developed by Bob Davies out of Tempe, Arizona. Bob’s company is called Advanced Device Design …

by David Crane defrev at gmail.com August 17, 2002 The bulk of this story is basically a re-printing of a post reply I made to a thread at TheFiringLine.com(a.k.a. TFL), along with a couple little changes and additional material and commentary. The title of the TFL thread is "Why the HKP7 is Superior to the Glock", and it was posted …

This just in: The Shrike 5.56 LMG(Light Machine Gun) upper, by ARES Defense Systems, LLC, is in production and currently available for pre-order(both in select-fire and semi-auto-only configurations), and the ARES Defense Systems site is up and running. If you remember, DefRev reported on the Shrike 5.56 and ARES Defense Systems some time ago. If it works as advertised, the …

DefRev is going ahead and publishing the following letter, which was submitted by an anonymous visitor of our site, due to the fact that it looks legitimate and involves a matter of weapon reliablility/user safety. However, in the future, DefRev will only publish this kind of submission… if it is performed using a valid DefenseReview.com username. In other words, after …

by David Crane david@defensereview.com The following article was written and published in June, 2002. It’s no secret that the performance of both the M4 Carbine and it’s 5.56x45mm caliber have, so far, been somewhat less than outstanding in the war against Al-Queda forces in Afghanistan. In short, the enemy hasn’t been dropping quickly enough when they are hit. Apparently, the …

I was talking with one of my brothers about some different calibers and velocities. Something we often talk about. This led to the IPSC’s Power Factor, which is simply Bullet Weight in Grains, Times Velocity, Divided by 1,000. This is an easy formula that one can use when comparing loads… but doesn’t take into effect Caliber. W x V / …

The HK MG 43 LMG/SAW is a 5.56mm LMG designed to go head to head with the FN Minimi/M249, IMI Negev, and Vektor Mini SS LMG’s. Initial word on the MG43 is good. Dan Shea’s written a preliminary piece, along with photos of dissasembled parts of the gun, in the June 2002 issue of SAR(Small Arms Review). HK is currently …

Ya’ just gotta’ give it up to someone that can invent a better mousetrap. Rich Fitzpatrick of Magpul Industries Corp. appears to have done just that. Fitzpatrick is an ex-Marine who’s never much liked the M4′ carbine’s collapsible buttstock. He’s always felt it’s a bit too flimsy, doesn’t offer quite enough adjustment, and generally sucks ergonomically, thus providing a less-than-ideal …

Pete Carber, of Custom Arms Company, Inc.(CAC), built a special custom Glock 22 for an American Handgunner article that appeared in the May/June 2001 issue. The article was written by Andy Stanford. The custom G22 was built using a Caspian slide, Bar-Sto match barrel, Lightning Strike’s aluminum trigger and skelotonized firing pin, and MMC sites. Carber also performed one of …
