Sucks. I imagine this was one of the reasons they didn't want to send me one for testing. These things are insanely expensive. That kind of quality control is simply unacceptable.

I like the smaller MOA dots as well, particularly through such a small view port on the RMR. I don't see much point in using the larger MOA dots in any situation really. With your cheek welded to the stock, you aren't hunting for the dot. Perhaps the larger dot would be of value on the pistol setups... As for the Surefire lights, I have used the 1000 lumen Fury and the Scout light variants. I didn't like the Fury since it was more of a wide beam. It wasn't worth the weight penalty. I really like the TIR reflector on the Scout series. I don't find the 500 lumen heads to be overpowered at all. Some of the lesser model Surefire's don't have the TIR reflector glass. Some might, I'm no expert on it. I wouldn't have a problem with using the polymer bodied light. I'm not sure what kind of weight savings you'll be looking at. I'd imagine it wouldn't be much since the Scout series themselves don't weigh very much to begin with. With the Ava Tactical mount, we found that it was best to piece meal the assembly. We bought most of the components from Amazon actually. We bought the Outdoorsman flash lights for the body and the tail cap. We then replaced it's 170 lumen head with the 500 Lumen Scout light head. Some could live with 170 lumens, and have themselves a rather inexpensive weapon light package. These options on a SBS are going to be awesome. I'm always envious of those builds. Another option for you to save some weight is to replace the magazine tube with the titanium 5 shot variant that carriercomp makes. You'll save a few ounces where it counts most. Use of the Scalarworks rail and RMR will save you some weight too.

Perhaps it is enchanted? I can see doing it on gunbroker where the listing is free until sold, but eBay? Pass.

Email complaints rarely go anywhere. I'd call to discuss it with the manager. I'd imagine if you complained enough, they'd offer to re-coat the parts. I know you won't find the parts useable for your builds -- But I bet you could sell the parts for a premium to people who don't care. I have done coating on AR15's as well. I never did NP3 since it was rather limiting on my color options. I don't like the fact that you can't Cerakote over it. I've been building some ultra lightweight builds lately. I like to keep them with an optic and a light and find myself in the mid 5 pound range.

What did Robar skimp on? Or were there just some cosmetic defects? The carriercomp follower isn't plastic. It's aluminum as well. The oversized safety can only be felt on your trigger finger when the safety is engaged. When the safety is off, you can't feel it at all.

An SBS setup lightweight would be a good build. I haven't gotten to fire an M4 with the Scalarwork/RMR combo. I have the units here. The build quality of both is very nice. If I was building mine again, I would elect for the RMR setup over the Aimpoint T1's. Are the iron sights too low for you? With the RMR, the dot is just above the iron sights. If I was building up a SBS, I'd add the following accessories; Carriercomp 5 shot titanium magazine tube Carriercomp magazine follower Geissele Hammer FFT Trigger FFT Disconnector TTI Shell Elevator TTI Oversized Safety Meprolights Night Sights Scalarworks top rail Trijicon RMR Optic AVA Tactical Light Mount Surefire Outdoorsman Light with a Surefire Scout 500 Lumen Head I might add the GG&G bolt release, I have mixed feelings about it though. The only aftermarket bolt handle worth owning is the carriercomp one. The rest have been, "Meh." Either poor fit, heavy or bad machining. I might keep it with just the fixed stock. The collapsible stock is cool and all, but the fixed stocks can be faster. Since it is a Class III device, shipping the weapon to Robar for coating isn't exactly easy. So what I would do is a selective part refinishing in NP3+. Mostly components out of the trigger group, the recoil spring plunger and pistons.

Good deal! You'll really like the shortie. I wish my burnt bronze/nickel boron M4 was built around the shortie.

Anytime. Look into TTI parts. There are a few nice upgrades there for the trigger pack. I currently have one for a client that is getting the tti shell elevator, tti safety, FFT hammer, FFT disconnector and FFT trigger. It's going in an H2O, so I'm having the internals and the trigger guard itself coated in np3. My the weapon is being exported to Australia to pop some pigs. I've got a Trijicon RMR on a Scalarworks rail and an Ava Tactical light mount going as well. All np3 coated. Even the Surefire light I built for it is being Cerakoted to match the np3 finish. The collapsible stock I got from HK is being coated in np3. Including all the internal hardware for the stock and pistol grip. The sling is one of those black and white kryptec vcas QD padded slings hooked to the Ava mount up front and a IWC QD mount on the collapsible stock. All np3 coated.

1989 import ban was all Bush Sr. Clinton was the 1994 Assault a weapon ban with the sunset clause.

BATF told Benelli to stop selling the H20 after Benelli attempted to skirt the law by having the M4's coated in NP3. I believe 60 - 70 M4's with collapsible stocks and full length magazine tubes made it out into circulation before they were shut down. Many of the upgrades are worthwhile on their own merit for the M4. So 922 compliance isn't all terrible and a complete waste of money.

I'd put OEM internals into the Promag stock. Mainly the pins and the unlock button. You can source the parts from places like Numrich Arms.

It wouldn't be easy to mount a picatinny rail to the bottom of the OEM or FFT Handguards since that is where they handguards meet together. Your best bet is the m80 or the Promag one suki has if a bottom rail is mandatory. I've modified the Handguards in the past to fit weapon lights. It was a lot of work and no where near as solid as the AVA Tactical mounting solution.

No modifications needed to install it.

Normal. Every m4 does this. It's self limiting. On my 12k+ m4, it's almost polished smooth and beveled.

I would blame the Froglube and the cold conditions. You should be good to go with a proper lubricant.

I find the M4 to be a rather heavy shotgun for its size. It isn't that the weapon is heavy per say, but it slows the ability to swing the weapon from target to target. I notice this issue gets worse when you start bolting on heavy components to the fore of the weapon. This is one reason I really like the M2. So so any chance I get to minimize weight up front, I'm all over it even at a price premium. The weight reduction of the titanium tubes basically equates to the number of additional shells held in the shotgun. So basically you're able to add capacity without the weight penalty. I've never seen a bad full length magazine tube. I have seen a lot of bad magazine extensions on the market. Even the Benelli OEM one I had wasn't that great. So as long as you're buying full length -- you're good to go.

I would try another brand of ammunition first. See if the problems continue to happen. Try running some buckshot and slugs through it. Inspect the the fired rounds and see what kind of primer strikes you're getting. Do they look solid or anemic? Can you describe the style of shooting you're engaging in when these failures occur? IE: rapid fire as fast as you can or slow pace shooting (at least one second gap between shots). The cold weather and whatever lubricant you're using could be an issue. If the lubricant is thickening, it could prevent the bolt from fully seating. This would push it out of battery slightly and prevent the firing pin from making full contact. I would experiment with a different lubricant to see if this aleviates the problems. If they continue, I would reinstall the factory trigger group components and see if the failure continue. This will help determine the area that is causing the problems; Ammunition issues Lubricant issues in the cold failures caused by damaged or improperly reassembled components. This is unlikely. I would have contacted Tim at FFT and reported the issues I had with the bolt handle. I'm sure he would have replaced it. Even now, it might be worth trying. I do agree that the carriercomp products are better. They're just harder than **** to get.

Titanium tubes are about 5 ounces lighter than the OEM unit. Plus the aftermarket ones count for 922 compliance. I have both Carriercomp and FFT. Both function as desired. Carriercomp tubes match a little better and have better machining than the FFT. In the end, it's a threaded pipe.

Who made that?

Thought those rubber pieces came off via the screws all along the rail? I never tried taking one apart.

F5! sucks about the Surefire rail. I wonder what they couldn't take apart? It looks easy enough to disassemble.

Not cheap, but the parts you want are here and in stock: http://www.gunpartscorp.com/Manufacturers/Benelli-33150/Shotguns-35372/Semi-AutoShotguns-40729/M4Super90-40596.htm?page=7

Just keep your receipt. I'd try fitting Benelli OEM parts into the collapsible stock to make it functional. Some of the small hardware like the pins that engage the receiver extension would be rather easy to replace.

Moar heat is required. Solicit some assistance from another to help hold the receiver while you twist.

We call it Muslim kryptonite.
