First AR Build, or rebuild actually
So here's the deal; I've had a Colt M4 with a Rock River upper for a few years now and I love it. Runs great, has seriously never jammed, my only issue has been the front sight. It was tilted about 5 MOA to the left out of the factory, so it took me a while just to zero in cause I couldn't figure out why I was totally blanking at 100 yards. Even once I got it zeroed I quickly switched to a red dot cause frankly the steel sights just suck. Sight radius is too short and the front sight post is too thick. I got an MBUS rear sight to put behind my red dot and called it a day for a while. Unfortunately I live in the Democratic People's Republic of New York. So my rifle came with a fake adjustable buttstock and a muzzle break that's as hard to clean as it is ugly and it just pisses off the people next to you at the range. These two things, plus the fact that I feel like my front sight post is worthless and just in the way of my red dot inspired me to start tinkering. I swapped out the stupid AWB legal rifle length buffer tube with a carbine length buffer and spring (that was confusing when I was trying to order parts) for a genuine rifle length system and installed an ACE Skeleton. One problem solved. Next I want to upgrade the trigger with a drop in, pretty sure I want a single stage, but havent decided which one I want yet, open to suggestions. My dream AR would also have an 18" cold hammer forged barrel with a mid length gas system, for a little extra velocity and accuracy, and a free floating rail. Since nobody offers a complete upper like that, at least not that I've seen, I decided to do it myself. Orderd a Daniel Defense 10" M4 rail and the wrench for it, but the 18" barrel with the low profile gas block is back ordered 6 weeks. My current 16" has pleanty of life left so I figured I can stick with it for the time being. Problem is that awsome front sight post again. I was thinking about cutting the top of it off and filing it right down to the gas block to make a low pro out of it, but DD's websight says the M4 rail has an internal diameter of 1.45". I measured my front sight post and best I can tell it would be 1.5" after my mods. I'm wondering if anybody has experiance with kind of thing and also if it's even possible to install a low frofile gas block on my current barrel if the M4 rail doesn't fit over my modified gas block. Also, what's the best "muzzle device" I could install living in this socialist paradise? Thank you to anyone that could help.

PWS556 is Communist state legal it works great and is wonderfully obnoxious.

I have a shaved FSB under a Troy TRX Extreme tube. I can't remember the I.D. but I imagine you can find it on their site.

Thanks, checked out PWS, those are some good looking muzzle devices. That whole thing drives me nuts. I've tried researching the AWB which is still effective here in f*^*ing NY and from what I've read there is no definition of a flash supressor. So WTF? Don't "muzzle breaks" also reduce flash, maybe not as well as a dedicated flash supressor, but to some extent. I'm tempted to just throw on a standard A2 "muzzle device" and take my chances, but I've actually heard stories of people getting charged for a class D felony or something and fined $10,000 or $15,000. So I'm trying to be a good serf, but it's hard to tell what's "acceptable".

Typically, muzzle breaks increase both flash and concussion over a flash hider, but they help control recoil.

I don't live in a Communist State so I have no idea what the laws are, but I would find someone in the know and talk to them to see what's legal and what isn't. Maybe contact a local ATF office?

The PWS556 has been deemed suitable for use in your state. I'm sure PWS would be more than happy to answer any Qs you have.

tsully85 11-27-2011 05:24 AM

Appreciate it. I'd just love to know who actually determines what's suitable and how. Cause from what I understand the ATF never had a clear definition of a flash suppressor and it hasn't even been their juristiction since '04. Since then NY has been enforcing a clone of the federal AWB and they've never bothered to determine that either. So is it up to the police to determine (really doubt they'd care anyway) or some state buerocrat that drops by ramdom shooting ranges to harass people? Sadly, I wouldn't be suprised by the latter in this state. Pleanty of ADA's looking to make a name for themselves.

Unfortunately lawyers/bureaucrats determine what's legal and it seems in this case they didn't care what was prudent and reasonable. Don't fight it, you're stuck with NY laws unless you move so go with the most acceptable option that's legal. You initially mentioned an 18" barrel with midlength gas but rifle length gas might be a better choice - are they backordered too?


On the canted front sight, I wonder if instead of a misaligned gas port if the barrel isn't quite right in the receiver? Worth a look.

As far as I know DD only offers the 18" in carbine or mid length, and yup, unfortunately the 18" with the low pro block is back ordered at least 6 weeks. I called and they told me it's not in very high demand, so they'll get to it when they get to it basically. As for the front sight, if you look close enough you can see that it's tilted to the left with your naked eye. Not the biggest deal, but I expected better quality from a "match target" rifle. So my rear sight's been cranked about 5 moa to the left since I've owned it, that's zeroed. Annoying thing is I can't really adjust for wind cause I'll forget where zero is. That's why I'd kinda enjoy mutilating it to fit the M4 rail.
