It has come to my attention that Issued Military M9's still use the 1st generation locking block due to technical data package (TDP) restrictions. If I buy a new commercial M9 as a civilian will it have a 1st or 3rd generation locking block? If you have an M9 in your collection please chime in...

So today I'm sighting in a 20" AR in 5.56 with an ACOG and want to be zeroed at 50 yards. According to my ballistics chart at this zero a 62 grain M855 will be 1" low at 15 yards. So I decide to sight in at 15 yards and get my hits 1" low from bullseye. I'm hitting perfectly 1" low at 15...

On the Trijicon MRO the difference between red and green version is significant, with the green having only about 20% the battery life of the red version. Is this the same thing with the ACOGs (TA02/TA110)? Trijicon's website lists the same number (12,000 hours on setting #4), but I wonder if...

I have been torquing my rings to the spec provided by these companies with a drop of Breakfree CLP on the bolt threads. A friend of mine told me this method is incorrect, and I should reduce torque by ~30% when using lubricated threads, as the spec from the manufacturer is for DRY threads. Is...

So I got the new MRO Patrol with the QD mount. Being QD it stands to reason that you should be able to hand-tighten the bolt with just fingers, however when tightening as hard as I can the mount starts to loosen after 3 rounds out of a 5.56 rifle. There is no torque spec in the manual for this...

I was at Cabelas and purchased an FNX-45 Tactical in FDE. The background check is done and they are finishing the paperwork. One of the employees, a man in his 50s proceeds to do the third serial number check. He picks up (my) new $1,300 gun and: Racks and drops the slide multiple times on an...

In thinking about which handguns are the most durable without preventative maintenance I thought it might be interesting to compile a list of recoil spring assembly (RSA) replacement intervals from various manufacturers. Which pistol can go the longest without replacement? Initial list...

I heard a rumor that firearm frames in FDE, OD, etc are weaker than the standard black frame due to less carbon black in the mixture to absorb UV energy. Is there any truth to this?

Living near the ocean rust on my 12 gauge shotshells is a common occurrence. Modern shells use brass-coated steel in the hull. Here's my question: Will using slightly rusted shells, assuming they are safe pressure-wise, damage (scratch) the steel in the barrel chamber during loading and...

LGS claims to have German-made HK45's (recent manufacture). I thought ALL HK45 production was shifted to New Hampshire circa 2011. Anyone know anything ?

I've mounted plenty of scopes in my 10+ years in this hobby and have always used the L wrench that comes in the ring package, usually a T-15 torx variety. I have read plenty of articles about how easy it is to apply too much torque, which crushes the scope tube, strips out threads, etc. So I was...

Several of my rifles / shotguns have this look to the chambers - all of the ones with this look are chrome-lined. What is this? Is it rust? It looks like something that could have been used to thread the barrel into the receiver, like a brazing or some kind of heat mark. It will not come...

A long time ago the first M1A I ever got needed a gas system cleaning, so I looked in the Springfield Armory manual and it said "use the combination tool to remove gas plug". No other instructions, and certainly no mention of using a gas cylinder wrench or how to hold the rifle. So I stuck the...

Did some shooting recently and used old car tires, stacked on their sidewalls, as a place to staple paper targets. After shooting a few hundred rounds of FMJ 40 S&W and 10 mm out of pistols I noticed that none of the rounds penetrated the tires! There was not a single hole anywhere to be...

So I noticed today while shooting that my adjustment ring to snug up the barrel had loosened to the point where the barrel could be wiggled forward and back easily. I probably put hundreds of rounds downrange with the barrel this way. Question: Does a loose adjustment ring on a...

So I know we're supposed to wear eye protection while shooting - guns sometimes blow up, case rupture, blow back with cans, etc. But I find that wearing them, especially while using scoped rifles is a major PITA. I can never see my scope because the oil on my forehead fogs the top of...

Let's say I have a gas piston-operated semi auto rifle - like an M1A, which says specifically in the manual to NOT add any lubricant to the gas system. Let's say I ignored those instructions and covered the entire gas system in CLP. What damage, if any, would occur to the rifle?

Question: Let's say you have a bolt-action rifle with a lightweight fluted barrel chambered in 300 Win Mag. You shoot 20 rounds in 20 minutes without allowing the barrel to cool at all. The ambient temperature is 80 F. What (if any) sort of damage can we expect to the barrel throat? I...

Have been reading several threads about the new mounting system on Surefire X300s breaking (on the Ultra B models). Is this a real problem or is the internet blowing it out of proportion? Got one in the mail for nightstand duty and concerned....

Would this be ill advised?
