That answers that.

Haha, I was just talking with another board member about the gas-plug O-rings on the M4, curious if they had ever had a wear issue. They said yes. They became enterprising and decided to remove them to clean, resulting in a slightly torn O-ring. I too am very detail oriented/want all the parts that might fail on-hand. So far I don't know what to stock, so I just bought a few O-rings in case I too become obsessed with taking them off. The M4 is a good tool. It is a tough tool. It is tougher than you are.

So you have removed/replaced this optic several times with no sign of POI changing when using slugs? It holds up reliably to 3" slugs (what killed my LaRue in a dozen rounds w/stock rail? I know you have handled LaRue (and apparently ARMS) mounts. How does this mount "Feel" in comparison. Is it on the same level of well-oiled-maching type quality? ETA: Correct, spelling is not my forte. I much prefer the spoken english language to the written. From what I understand, you adjust the lever by tightening/loosening the "nut" on the other side of the mount and then lok-titing it in place after you find where it belongs? The design of this mount is VERY appealing, my concern is over the quality/durability/repeatability. *ETA: You also said "We" every time you referred to an experience with the LRP. I take this to mean your unit/department/whatever. Can I infer by this that there are multiple users that you communicate with who rely on this unit and who also have no issue with durability/zero-repeatability/anything else?

Flush-fitting MOD Trulock is what I went with. Slugs, buck, birdshot. Does well with all.

I too have looked into this unit. Concerns of mine: Does it have repeat zero? Does the pressure on the screw cause stretching of said screw? Does AIMPOINT even manufacture it? I wager that they buy it from someone else. The fact that the lever is a caste part bodes not well based on tonnes of broken ARMS levers littering most military ranges. ETA: Also, when I pick up the phone to call LaRue...I get a knowledgeable LaRue employee. Not a voice mail. not a message machine, not empty promises to call back from a tape recorder. *They picked up their phone *

http://www.gggaz.com/index.php?id=80&parents=60,63 Call them and MAKE SURE it will work for your application. I do not know if they bill it as M1/M3 because they assume M4 means collapsible stock, or if it is billed as such because it won't fir the M4 at all. Again, be sure of your application before you do any spending.

Mine stays warm day and night, and has NO scars. Maybe that's because I sleep with it at night and leave it under the covers during the day.

I have never heard of any issues, and it comes highly recommended. However, I still feel the need to ask. Other than installation (which I will update you all tomorrow on how that works out for me...), has anyone had a problem with this? I know Duggan did until he lok-tited it (user error, as he admits), but nothing else. Has anyone ever had this thing go TU even after lok-tite or anything?

I would not accuse someone with such an eye for detail of "not paying attention". I am disproportionately excited about this rail though. I want it. I want it bolted to the top of my M4 with an LT mounted T1 cruising along atop it. However, patience is a virtue. I DID get the spring in the mail today. In the end, I am one who has to hold, touch, look at, and appraise something with my own senses before I can TRULY endorse it. When I say "This thing is good", I attatch my reputation to it as well. People associate it not only with who made it, but who introduced them to it. While I have always maintained that you are one of the most polite/best written/spoken manufacturers who has an online presense, it was not until today, at the recieving of the spring, that I truly appreciated the quality of what you are doing. Sure, I saw photo's, heard reviews, ect. But today when I took the spring out of the box and remembered all my dissapointment with: Surecycle, Wolf "generic" springs, Benelli M1S90 springs, ect. I could not help but smile with confidence as the time ticks down until I have my rail and Ti tube. I do not say this to imply that I doubted the quality of anything, but simply to say what everyone who has ever owned a fine automobile or sports car will tell you. Watching it, looking at it in pictures, seeing it on TV. Nothing compares to feeling the soft snick* of the shifter as you slam 3rd gear and listen to the cacophany of screaming exhaust yourself. And so it is with well-machined parts, although not quite as liberating. ETA: this hard/brittle stuff is why I have not condemned the KZ design for being softer than GG&G. I HIGHLY! doubt that the GG&G bent itself into two pieces. Perhapse it was heat-treated too aggressively and it snapped. The KZ bolt may not do this at a lower RC level. I do not know, but until you have a Bolt Charger out, I am running my stock one, being as noone will sell me their Design Concepts one.

Indeed, but not at the expense of that rail! I did, however, miss this: IMPORTANT! We have been experiencing product demand similar in nature to that of all firearms related merchants. Similarly we have recently found it necessary to ask your help in enhancing our efficiency, and afford us the opportunity to focus our efforts on production, while keeping phone and email correspondance to a bare minimum. I promise no more phone calls until things are up to speed! I am just a curious person who likes to know more about metallurgy than I can comprehend.

You are going to slam that heavy wrecking-ball of a shotgun right into your nethers if you run a single-point.

I think that Kip's spring is finally the product that has ended my search for a spring for a FL tube. I did not doubt him, or Duggan, or others who love it, but I wanted to handle it myself. Well, mine arrived today and it is exactly 33.25" long, and has VERY stout coils. Not over-done, just right. Feels close to stock. I squeezed it a few times (sections of it) and I don't think this one is going to take NEAR the set a stock Benelli spring will. It just felt "springier". Very impressed. I can't wait until the Ti tube arrives and I can test it!

Alas, Brownells informed me that I would NOT be recieving a design concepts BCH. They have been discontinued. This sucks. Oh well, I would rather Kip have the money anyways.

+1, Kip is the only person out there listening to people on the user level, assessing the need himself, and then acting upon the vacuum in the market. If he maintains his quality at it's present level and can expand his operation without sacrificing it, while keeping his prices within a decent percent margin of their current level, he is going to make some real money off of this, and I for one hope he does. I think ingenuity and craftmanship should be fully rewarded. This isn't China. THANKYOU FOR YOUR TIME and ENERGIES KIP!

I ordered a DC Titanium bolt handle the other day. Brownells told me it would be in my hands in 10 days. Either I got part of the last run, or they will notify me that they are going to remove a charge from my CC. Assuming I DID get part of the last run, am I to understand that I lucked into buying the ONLY aftermarket bolt that is structurally CORRECT until yours hits the market (Please, by all means, DO NOT shift focus from that rail! I dream about it as well).

I guess all those FL tubes and optics have no place on my M4 then, lmao

Careful with that snap ring. Peter North ain't got nuthin on how that spring will launch across the room if you aren't prepaired for it.

When I was a kid my Dad would not allow me to use a scope. I got a scope when I was a teenager. I can shoot very accurately and among my friends I do not know anyone who can out-shoot me that is not significantly more experienced. Irons or glass. I attribute this to my father making me properly learn the basics. Irons. Use them. Master them. Never forget them. They are bomb-proof. All else is supplemental.

Supposedly that bolt charger weighs .3oz My roommate just took my stock bolt charger up to the university and is going to weigh it and see how much it weighs. THe issue here is balancing strength and weight and size. It needs to be large enough to grab Weigh little enough not to stress/break under high-G accel/decel, and Strong enough for it's weight. Also, weight distribution probably comes into play as well. Hang more weight on the outer end, it stresses the middle/base more.

Yeah...pretty much. Try running an expensive QD mount on it like we have. Then you can be one of the first-hand informed, lol. I estimate 6-8wks on te new rail from my conversations with Kip. He should have them machined in 4-5 wks + ano-time.

I personally think the red-dot is a good idea, which is why I am buying Kip's rail when it comes out (It is a sure deal, and I have badgered the poor man for info on it enough that I am pretty much required to buy it, lol) and mounting an Aimpoint T1 or Trijicon RMR on it (leaning heavily to the T1). The red-dot is much faster than ghost rings especially when using slugs. An aftermarket pistol-grip is pointless. Stick with the stock stock, even though it may be a wee long. On another note, Duggan, how hard was installing your GGG bolt release? Is it the whole thing, or do you have to modify the stock one to replace the button? How has it held up, IIRC I have heard of people saying the screw holding the pad in place un-screws randomly or something back when I was considering one for my old M4. Also, do you too have the titanium bolt knob? I have heard of other bolt knobs bending and recall you mentioning that you bent/broke one. Story on that?

Yep, simple stuff. Years of bachelorhood even allowed me to forgo the use of a strapwrench to unscrew the tube.

+1 and FWIW, LaRue gave me a full refund on both the optic and mount when my M4 shredded his mount. I saw no need for the optic since the M4 was why I bought the optic. Mark may make a total fool of himself on his message board at times, but make no mistake, he stands behind his product 100%.

+1 I heated up the area where the tube screws in with my heat-gun, wrapped a pair of boxers I had laying on my floor around the reciever, set it on my computer chair cushion that I am sitting on as I type this, and took my man hands and un-screwed the tube slowly while heating the reciever periodically. It was very simple. No CLP was boiled off, no smoke was created, nothing was damaged, and no animals were harmed. I am not one to go meddling with things often, but this was simple and well worth it.

Collapsible stocks are a bling item pretty much. The full-length tubes can be had as cheap as $100 (for a good one).
