Quote HistoryOriginally Posted By elucidate: Well this thread is WAY off track. Let's get it back. This is a 100% real rifle. https://i.imgur.com/TSIjB9I.jpg Some key points: The HRT mount is often used within Regional as well as HRT, it all depends on if said regional guys were involved in the early testing of the new rail and accessories solution, if so they tend to keep the stuff vs moving over the the DD mount. The DD mount is definitely more common though. Commando barrels are 'the' barrel that is correct for regional SWAT. Some are converted 14.5s that are chopped, although those are now rare. More common are regular 11.5" commando barrels. The newest are Colt CAGE code marked barrels, you will see these where people have had barrels replaced. Not all barrels are Colt, although most are. There are a good number of the RRA marked Hogue grips out there as people moved them over from their previous RRA lowers. Colt lowers come from multiple sources, including Crane, so some are weirdly marked or older, such as the one above is a M4 Carbine, US property marked. Not an M4A1, although many are M4A1 marked. With lasers, both PEQ15 and LA-5 are being used. There is a large variety in the finer details, mostly related to how long the particular person has been in position. Thanks for posting, based on the pics previously posted, Surefire suppressors any idea on the brake. |

Quote HistoryOriginally Posted By ResponsibleSecond: https://ibb.co/cxr926D I picked up a RRA lower for my DDC HRT build. I want to clone their LE markings. Colt and Bushy do engraving, but it looks like RRA does a stencil of some kind. Anyone have an idea how I can achieve this look? I picked up an old ban era RRA LE carbine specifically to clone with and can confirm it's laser engraved. |

Well the new RRA grip has the new logo and I’m not digging it. If anyone wants it send me a message.

I believe it sold for around $800, before the panic prices really kicked in. I considered bidding on it, but at the time, I didn't want to bother with it when I really just wanted the receiver set to potentially clone an updated 11.5" FBI rifle. In retrospect, I'm sure I could have sold off the extra parts these days.  Attached File Attached File Attached File Attached File |

The grip in the resent real deal post has the second gen logo
So I’m wondering if the RRA lowers used had some of both logo. The newest third version of their logo is ugly IMO

Sig optic and mount on the other rifle. I could be wrong, and it's hard to tell in the photo, but I think that's a T2 on a Daniel Defense micro mount, which is common on Regional SWAT rifles. It looks like it has the curved / tapered appearance of the DD mount under the Aimpoint, vs. the straight vertical sides of the Larue mount.

What would be appropriate for a hrt upper, stainless or nitridate sgb. Also does brt still offer the service of installing the insert, .065 would that be the correct size or which brt tube for a mix of operation suppressed and unsuppressed.

They still do the insert, I just shipped mine out to them. I told them I'd be using a Colt 6933 barrel, carbine buffer spring, and H2 buffer, unsupressed. They were quick in communication and I went with the .065 insert (.067 gas port size). I had considered the gas tube, but BRT said for a duty gun they recommend the insert. |

Lol, yeah I was going send mine out as well to get pinned, but dimples are so much easier to do, so that was last nights project. With regards the brake I think the sfct may be the way to go, but I was hoping to make the upper as close as possible. Although it seems there is some differences in the pictures from page 1 with the eotechs and mbuis to those on page 50 with the aimpoints. |

Question for you guys:
I obtained a DDC HRT rail, and was able to snag a RRA stripped lower. I have all the components to complete my build, and have it be relatively "clone"-ish. Major deviation would be muzzle device and irons- I'll be going with an open tine warcomp and KAC micros. Optic will be a T-2 in a FDE unity mount, so I guess that counts too. I have two barrels laying around. 1- Colt 11.5 HBAR with FSB, I have a G gas block standing by for this one 2- Marvin Pitts 11.5 dimpled E3 barrel, I have an SLR gas block standing by for this one My gut tells me to use the Marvin barrel as I feel I have enough deviations that it doesn't really matter, and overall it would be the better shooter and something that would keep my interests longer. Thoughts? |

The irons and optic mount are going to be very obviously incorrect though, I think it’s necessary to go for the correct parts there. I don’t have the correct optic yet, and I think it kind of ruins the overall look. |
