Quote HistoryOriginally Posted By pezboytate: It was designed to fit barrels that are .845" behind the FSB. Thanks - that's what I needed. You may have saved me $200 and a muzzle heavy musket. I'm thinking I'll revert to the classic plastic handguard version for now. Here's all they say on the KAC website, which at least got me thinking about it: Lighter barrel profiles work best (Government contours). Heavier barrel contours may require modification to the inside of the rail. Originally Posted By borderpatrol: Would a Vltor compensator be legal? No good; it reduces flash per their marketing blurb. AWZ1287's link to this is looking like just the thing, though, and AIM specifically states that it's Cali legal, which is helpful for those of us who worry about such things. Here's hoping it won't direct too much concussion to the side: Similar to A2 style brake, the open top slots and closed bottom increase muzzle control and reduce dust signature making it compliant with California Featureless laws. The end is also blocked to reduce recoil. 1/2" x 28 threads .223/ 5.56 compatible. *This device will not reduce or remove flash.

I have yet to find any real answers to that same question. I even posted a thread in the LaRue forum but got no replies. Having had both, I can tell you that the differences are minor. The locking lugs on the bottom side are in different places, the sides of the mount are a little more rounded on one versus the other - little things like that. No major differences that I could tell. |

Is it more correct to leave the top rail covers on or off? I've heard people say that they are liable to melt under heavy use. Although I have seen pictures of the covers on in the "in field" pictures.

People here will tell you that the top cover should be left off to allow the barrel and gas tube to vent / cool more effectively. I have never heard that once in the Army in reference to either M16s or M4s. When I was carrying an A4, I had rail panels on the entire thing because I thought you were supposed to have them on to protect the rails from damage. I'd be curious to know if it was ever addressed in an updated TM, PM magazine, or other military pub. Nowadays, people leave them of their M4s completely to make the handguard skinnier and because they don't want to be bothered to put them on. It's not surprising that Soldiers and Marines wouldn't know about leaving the top covers off, if that's what KAC or anyone else recommends. I'm just saying that almost no one in the military has heard that.
I can appreciate the concept of allowing the rifle to cool more effectively, but the M5 RAS is long with a lot of vent holes in it. I think the practical effect of leaving the covers off is probably minimal, unless you're trying to burn the barrel down with repeated magazine dumps on burst. To answer your question, as you said, most photos show people with covers on the top - sometimes both, sometimes just the rear one, and sometimes the front one. About 10% of the photos of have show no covers on the top. So if you're going for the "look" of a 2000s era A4, I'd suggest putting at least the rear top cover on. |

The KAC RAS installation manual says to cover all unused rail space to protect the rail surfaces and to protect the user's hands, for what that's worth. I left the top covers off of mine because it's already pretty front heavy; every little bit helps.

Here's the state of my budget/parts box Cali legal build. I just got the Shark handguards on, and had to tweak them a bit to fit on the Armalite HBAR. It's still a work in progress as the budget rebuilds.
Armalite 20" HBAR upper, Eotech 552 and Matech BUIS (can't afford an ACOG, lol!), old Fab10 blind magwell lower with an A2 stock, and a BFG SOC-C contractor pak sling. I still need a better looking muzzle device (no flash hiders allowed), swap the Ergo grip for an A2 style, and a real lower (which will require losing the pistol grip, alas). The old school front sling loop in my sling pak was shortened by the guy I got it from, so I may switch to a Specter, though I like the position of the DD qc connection. I'm thinking about getting the barrel re-profiled, because this is a front-heavy bugger.  The M5 didn't fit on the HBAR, as suspected, but it just took a few minutes with a Dremel to open it up. Here's the part that wouldn't fit over the barrel. The steel didn't feel like it would be too flexible, so I didn't whack it with a rubber mallet due to worry about cracking it.

Quote HistoryOriginally Posted By 86HMMWV: They may have changed their barrel dimensions in recent years. Mine was considered medium contour back when I bought it in 2010, and an un-modified RAS fits over it with no issues whatsoever. This was from back in 2007, and I didn't know much about ARs at the time (still learning!), but they had a huge sale blowing out all kinds of uppers and other gear. There was a feeding frenzy over at calguns, as we were just beginning to work around the Cali AW laws and build some ARs. The description didn't include any details about the barrel diameter, but I didn't care - it was an Armalite upper with BCG and CH for $350! I'm guessing this configuration wasn't selling as well as they hoped, with the 1:9 twist and heavy barrel. From the original sale: The M-15A4BA2 Complete Upper Assembly features a double lapped, chrome lined barrel. The Picatinny Rail on the upper receiver allow rapid and repeatable interchange of removable iron or scope sights, complete with A2 front sight. Each ArmaLite Complete Upper Assembly includes a forged upper receiver assembly, barrel assembly, bolt carrier group and charging handle assembly. All complete upper assemblies are test fired as complete rifles before shipping.

Here’s my current “16a4 clone”.
1. I do have a sling for it but I left it out of the pics because it’s pretty far from being correct- it’s a custom one from WTF in black MARPAT with my name in glow-in-the-dark tape. 2. Still trying to decide whether to overpay for an old tech SureFire M962, or use something more modern that works better but doesn’t look right. 3. I would like to have something clone-correct engraved on the lower (it was an 80%er) but I don’t want “Property of US Gov’t” on there for personal reasons. Is there a manufacturer with a roll mark that would be right without that?

Does anyone know for sure whether USGI M16A4s have either
always had metal trapdoors always had plastic trapdoors or early had metal trapdoors and later had plastic trapdoors (and an approximate date of the switch)? I'm not talking about any commercially sold rifles. Not looking for assumptions. |

ACOG finally showed up, so for now at least I'm going to call the build done. It's an RCO-M4 instead of the A4, but the deal was far too good to pass up and I'll share it with my M4A1 build so good enough. Otherwise, it's an FN contract upper with FN BCG and charging handle, and Knight's marked M5 RAS, VFG, and USMC marked rear sight. Lower is an 80% with a custom UID tag from Carolina Laser Works, FN A2 buttstock assembly and some no-name LPK. Sling is the VCAS NSN sling with M16 adapter and the mount is a surplus LaRue LT622SDO-A. Also have an issued/surplus OKC-3S for it as well.
My goal was to capture a "last standard issue" M16A4 from around 2015-ish. I know it's being utilized in all branches still today, but when the USMC started phasing them out of standard issue service in 2015 in favor of the M4, it marked the end of the M16 lineage. My collection is geared heavily towards full-size standard issue rifles throughout the years so building this to be a sort of last call on the M16 felt appropriate. The only thing I'm unsure on is the light. I had an old M962 kit laying around so I figured why not, but other than the PEQ-16A, what other lights were issued/in common use around 2012-2015?

Otherwise, it's an FN contract upper with FN BCG and charging handle, and Knight's marked M5 RAS, VFG, and USMC marked rear sight. Lower is an 80% with a custom UID tag from Carolina Laser Works, FN A2 buttstock assembly and some no-name LPK. Sling is the VCAS NSN sling with M16 adapter and the mount is a surplus LaRue LT622SDO-A. Also have an issued/surplus OKC-3S for it as well. My goal was to capture a "last standard issue" M16A4 from around 2015-ish. I know it's being utilized in all branches still today, but when the USMC started phasing them out of standard issue service in 2015 in favor of the M4, it marked the end of the M16 lineage. My collection is geared heavily towards full-size standard issue rifles throughout the years so building this to be a sort of last call on the M16 felt appropriate. The only thing I'm unsure on is the light. I had an old M962 kit laying around so I figured why not, but other than the PEQ-16A, what other lights were issued/in common use around 2012-2015? https://i.imgur.com/oapquaZ.jpg I like that idea! I had a USMC-marked KAC rear sight but sold it due to not really seeing any used in conjunction with the ACOG when I looked back through the real-world pics in this thread. To be honest, I've seen mostly the same, though I do have a few news photos where they're visible. If anything, it seems like the ACOG was usually on the standard acorn-nut mount than a LaRue, though again, there's examples of both. |

You caught me, it's about the only non-FN/issued part on the gun. I was looking at one of those, but I was also wondering if FN was using the same A2-eqse grip from the SCAR 16/17's when they were supplying lowers/rifles to the military. I was looking at this guy. https://www.gunbroker.com/Item/888656380 Thoughts? |
