The FFT trigger is a nice 922® part for compliance. The trigger pull is reduced a little from the factory trigger. It's a worthwhile upgrade. Here are some better pictures. The color here is how it actually looks in person.

False lighting sucks. The receivers look nothing like these pictures in person. Function test of the AR seems good to go. I have to tweak the buffer to allow the unit to retract further back about a quarter inch. Currently it can't pull back far enough to lock the bolt back. I'm just going to cut the tip of the rubber bumper off to give it the clearance needed. I like how the black lacquer came out on the receiver markings. It was a PITA to do though.

The action feels like it is riding on ball bearings. I barely even feel the hammer when cocking it. It sounds different too. I'll take better pictures when I have natural light tomorrow. I think it looks better in person than in these pictures.

Sorry, took about 5 hours to put the M4 back together. I had to do some fitting to some of the parts due to tolerance changes. Example, I had to polish the pistons with 1200 grit sandpaper to make them cycle smoothly. Loading some pictures right now... The other parts next to the pistons are the shell release lever and the shell stop. They're all nickel boron coated.

More later...

I was worried they'd F this up.

Parts are in. Finally. Surprisingly, the order is pretty accurate. They didn't coat a few tiny pieces that go in the trigger group for some reason. Other than that, they followed the directions great. I'm in the process of assembling, Benelli M4 first. Here are a couple teaser shots.

When I talked to them years ago, the only model they would sell is the straight model. The breechere were limited to law enforcement.

I was going to say, nice wall poster!

It doesn't even look like you could collapse the stock with that riser in place. It would run into the receiver. The issue is that stock is on a M1014 M4, so it doesn't have the notches to actually collapse. That's like due to MT being located in Californiastan. I personally never had a problem with the cheek weld of the M4. The only issue that arises is when you try to shoulder it from the fully collapsed or middle position. Since the stock slides upwards along the receiver extension, it changes the cheek weld height as it collapses. You end up looking over the iron sights in the middle position. This is ideal when using an optic like a low mounted Aimpoint T1.

You can build your own H20 for sure. There are only a few parts that add some complexity to the job. Removing the ejector from the barrel is a real pain since it is riveted in place. Same goes for the detent and spring that ratchet the magazine cap in place. Both of these items could probably be left in place and coated anyway without any detrimental effects. Taking the tensioners out of the front handguard hanger might be a pain as well. This is why I did not have my barrel assembly coated in Nickel Boron. The end value wasn't that important. The barrel extension that inserts into the receiver is already nickel finished by Benelli. So the only functional benefit would be to the ARGO piston housing and as a corrosion inhibitor. This isn't that important since have you ever seen a rusted Benelli? So it's more of a cosmetic attribute. Having NP3 or Nickel Boron present on the locking lugs of the barrel would be a benefit over the regular nickel finish. It would be marginal at best. Another issue you'll encounter is if you're using a coveted titanium magazine tube. You cannot apply nickel boron or NP3 to titanium. So you'll be left with a paint option. That is why I opted to just have my barrel assembly painted in Cerakote. It'll fix all the cosmetic defects present, and add a layer of corrosion protection. Cerakote is far from just paint, it is a ceramic based finish.

Naturally being disassembled would be better, but it isn't a deal breaker. I had my Aimpoints painted with the mounts attached. It just wasn't worth taking them apart. Plus I hope the paint will "glue" the fasteners in place. As for how thin the Cerakote is, take a look at this picture. If you're familiar with how faint the engraving is on an Aimpoint T1, you'll know that they're maybe 0.001" engravings. Even with the metal flake Burnt Bronze finish, the engraving is clearly visible. Sometimes the thin nature of the Cerakote isn't desirable since it has a difficult time filling in blemishes. All of that work will have to be done prior during the bead blasting phase. Since it apparently takes UPS nearly four days to drive from Mesquite, Tx to Phoenix, Az, my parts won't be here until tomorrow.

bm4sbs was teasing. I never bought one. I'm not sure if they're actually for sale yet since I've never seen an end user with one. Perhaps they are for sale, and that says there is hope for the human race. Take a look at the manual for installing the stock. http://www.atigunstocks.com/img/cms/A.1.10.1431.pdf Granted, if ATI wanted to send me one of these stocks -- even temporarily to test out -- I'd be glad to do it. But from what I can see, I think it would be a step backwards in performance and simplicity of the M4. Of the stock out there, I'd rate them in this order; 1. Factory collapsible stock or the factory field fixed stock 2. Promag collapsible stock (cheap alternative to the factory collapsible stock, difficult to get since February though) 3. Factory pistol grip fixed stock 4. Urbino Stock (Love the LOP, hate the attachment method and boxy pistol grip) 5. ATI Abortion

bm4sbs is teasing. ATI is synonymous with crap. I consider them only a little better than Tapco. This particular stock has been labeled the Tactical Floor-jack and the Grip of Shame. It's overly complicated and seriously overpriced.
