RA Release XCR-M Will Be @ Shot Show 2011

Its the only thing they can come up with much like the lieberals and their spewing Harper has a hidden agenda...

If you can't get Loctited bolts out instead of using heat that may ruin a finish etc soak the bolts/nuts with WB40 it will break down the Loctite so you can remove them...
 
Once locktite'd they can't rattle loose. If your really worried about it use the red permanent. While it's not really permanent it's damn close and it'll never come out alone under an infinite round count. You'll have to heat the screws enough to melt the glue before you can remove them.

The threads on both the screw and the receiving thread must be completely free from oil and other contaminants. When you purchase fasteners in bulk, especially if they come from china, they will be coated in oil to help prevent corrosion. When threading a hole, some form of lubricant is usually used to help keep things cool. If the cleanout procedure is not perfect(Quality Control) the loctite may not cure and bond to the steel/aluminum, now you are relying on torque alone. There are a number of different formulas of loctite, so it is important to select one that is correct to the application and the materials you intend to bond.

What can also occur is that line workers get the false impression that the loctite will prevent the screws from coming out and may not even bring the screw to the correct torque, or if there are multiple screws, to have them all evenly torqued. So, loctite is not fool proof because if you are not on top of your QC you may send out a batch of products that will not retain the fasteners.

The rod caps on John forces 3 second/ 4000hp car are held on by 2 nuts each. I can not fathom a more abusive environment. I suppose they could machine interlocking caps that use taper pins to secure them but they haven't. Proper torque secures things indefinatley, lock tite is just a redundant compound or a back up plan. I'm still amazed at the trashing because of loose screws. Bolts and screws hold the world together. Their good enough to hold a gas turbine engine together, connect power to the rotors, hold the rotors on and fasten the linkage on a 20million dollar apache hellicopter but not a rifle? Sounds like user error. But it, inspect it, maintain it and it won't be a problem. My guess is the guys having problems are the same people that call for roadside service to change a tire.

You are not comparing the same environment, and I highly doubt that John Force's engine uses only two main studs.
 
@navy, I'm with you 100% on the quality control regarding romoving all traces of oil and , choosing the correct compound for the job at hand and proper torque. Anyone who owns a gun should also be able to maintain it, they are not rocket ships. Unfortunatley societys knowledge regarding matinence on their property went out the window with the introduction of hydraulic litters and electronic ignition. Few know how to change their oil so I guess it's silly to expect people to know what to do when they encounter an evil bolt.

I also doubt mr forces engine uses 2 bolt mains, probably 6 bolt. 2 straight, 2 splayed, and 2 at 90 degrees from outside the block but 2 bolt connecting rods as I've yet to see a 4 bolt rod.

I love how all the xcr threads get ruined by guys chiming in about the loose bolts. It's the only thing there is to complain about and any kid with a 5/16" wrench, can of brake clean, some Allen wrenches and a bottle of blue locktite can fix so it'll never be an issue. As I've said before, I stopped mine to each individual spring, pin and bolt, cleaned it and re assembled. While it's only got around 1000 rounds through it I have faith it'll never lose a screw in thousands more.

I likely constitue a small portion of the younger population that actually has any idea what points are... I've never used a screw driver to wake them up.

Sorry my error, I read rod and thought maincap for some reason, so you were correct. :p

The last 6 bolt engine I was inside was 4 parallel, 2 perpendicular, but that was a VH45. Now I only play with diesels and the odd vg30.

The XCR is a pretty nice sporting rifle and I imagine it would perform as well as any other properly maintained machine... flawlessly.
 
Lol. I have no idea what those are in. Planes? Old Indian motorcycles? Starship cruisers?

Subject: [Dtiquips] 2011 SHOT Show, Range Day

17 Jan 11

2011 SHOT Show, Las Vegas, NV, Range Day:

We're here in Las Vegas, NV for the 2011 SHOT Show, starting tomorrow.
However, the live-fire Range Day was today at a local outdoor range complex.

Aimpoint, LaRue, Gemtech, US Ordinance, Hans Vang, and LMT all had their
wears on display and available for live-fire for those inclined.

My notes:

There are currently a number of attempts to combine optics suitable for
close-range shooting with long-range capabilities, creating a rifle with a
wide spectrum of capabilities. Most are bulky and require close eye-relief,
but there is clearly significant interest in such a system.

Leupold's HAMR (Highly Accurate, Multiple Range) optic combines a compact,
ruggedized four-times optic with a piggyback, zero magnification
mini-screen on top.

Their CQBSS Mark-8 is a 1-8 times optic with multiple functions.

LaRue combines a long-range scope with a piggybacked Aimpoint T1.

Aimpoint has a offset mount that permits the shooter to sight through his
scope on top of the rifle, but, with a slight move of his head, switch to a
T1 mounted at a forty-five degree angle on the right side.

Again, all are designed to allow a sniper to fight his way to a position,
engaging close targets on the way, then switch to effective long-range
shooting once he gets there. And again, the price one pays is bulk, weight, and
close eye-relief.

LaRue and LMT, both well-known for high quality and superb customer
service, had on display 308 rifles, on the Stoner System. LMT also chambers
theirs for 243, 260, 338 Fed, and 7mm/08 Rem.

US Ordinance, makers of heavy weapons for the military, had on display
their M2 (Browning 50cal HMG). It ran fine, but the days of tediously
adjusting head-space (using "go" and "no-go" feeler-gauges) when changing
barrels is over! Head-space is "set" at the factory, and a barrel change now
takes less than ten seconds! Quite an advance.

There upgrade of the troublesome M60 LMG, called the M60E4, has finally
turned a historically untrustworthy weapon into a reliable one. In Vietnam,
we could not keep M60s running, despite meticulous maintenance. Those days
are now over! The E4 runs well, and US Ordinance will be busy for the
next several years refurbishing all the old M60s, now found throughout the
world.

I talked this afternoon with Alex Robinson of Robinson Arms. He will be
down tomorrow with his XCR, now available in 308. I'll have my hands on it
shortly! So, those in need of a battle-rifle in 308 will now have yet
another excellent choice!


Show officially starts tomorrow morning.

More later!

/John

Looks good except for that regular stock. I'm not a fan of that thing.

The new slogan: Shake, rattle and roll!! Now in .308 :p.

A PRS would probably look fairly sharp and fix the stock issue for a marksmanship rifle in .308. Would be interested in the accuracy of this rifle.

With regards to the bolts etc arguments. This rifle isn't a battle rifle. That's not hating, it's not anti XCR or any other garbage. It's the reality. Anything with that many bolts/screws etc that can come undone isn't up to the task of being misused by military personal. If it comes lose, or is lost and this affects the rifle actually working then it's not a battle rifle. The Kel-Tec RFB also isn't a battle rifle. It also has too many screws and bolts that could come loose. Screws through the safety and in the case of the RFB on the bolt release aren't acceptable for military use. For recreational use this doesn't really matter. In fact I'd rather have exceptional accuracy than battle rifle reliability for recreational use. It only matters if you have the expectation that this is a battle rifle when it's not.

Latest update by Alex of Robinson Arms today Sat Feb 12 2011...

A friend of mine was @ the Shot Show and spoke with Alex they discussed the release date of the -M from what he said to me it sounds like we are still looking at 6 months before it will be released...

This is incorrect. We're getting real close to pulling the trigger on production. I will let you guys know when I order the parts, then it will be weeks.
