15" rail choice for SPR build?

[snackgunner]

what 15" rail offerings are your favorite for quality SPR builds?

Geissele.

PRI tubes are nice, so are BCM. BCM KMR or MCMR have a nice diameter that feels good in you hand and gives you some weight savings with the heavier profile barrels.

Sionics.

I've only built one SPR with a 15" rail, and that was with a 15" MK1. That said, it excelled in that role. I had no complaints, loved the extra rigidity and beefed up barrel nut over other designs. The added weight helps imho through bedding these types of rifles down when precision shooting.

Nice. Which G rail is that?

I wish G would do another run of the mk1 rails

If you want the most accurate setup possible, the Aero Precision M4E1/M5 enhanced upper. While you are limited to Aero Precision quad, mlok, or keymod it's one of the only off the shelf upper/rail setups where the rail mounts to the upper receiver directly and does not contact the barrel nut.

If you open my safe pretty much everything wears Geissele or ALG rails, however the two precision guns are built with the Aero Enhanced uppers.

I used a 15" Geissele Mk8. Gives good clearance inside for MLOK attachments like bipods and is a solid rail.

[LMT/556]

I know you said 15", but the original SPRs were built around 12" PRI then KAC rails. Knowing that, LMT MRPs are an option and the receiver/rail is one piece. 18" SPR barrels are available, this one is a rifle length quad with a 20"SS barrel.

The BCM KMR is my rail of choice.

My first pick for basing any precision build off of is a MRP chassis without question. I prefer the LMT MRP w Rock 5R SS 18" over the above MK1 railed SPR w 18" SS barrel. Nice rifle!

The MRP Recce smokes em both though...:D

I'll be another for the Geissele. I'm using a 15" Mk4. Combo'd with a Vltor receiver, its very stiff.

Same here

My goto as well. As you know, I have this same set up.

[Don't Tread On Me]

Not to stray too far off topic as it isn’t a 15” length rail, but has anyone here had experience with the old BCM Mk12 upper offered with the Larue 13.2”? I always wanted one but I don’t think they were around that long. At the time I think the Larue was the longest offering in the market place when that upper was a listed product. Just curious as to how it balances out as opposed to the lighter, longer rails in the marketplace nowadays.

Papabear, what setup is that?

[nightchief]

Had trouble attaching a pic earlier...Similar set up to Eurodriver but without the cool night vision gear

[ViniVidivici]

I'm very happy with the VTAC Alpha Battlerail on mine. It's 13", but they do make 'em longer.

Light, solid, all you need and nothing more.

[Pappabear]

Papabear, what setup is that?

Its almost the identical set up as Eurodriver.
my set up is Colt Lower, Noveske 16 barrel, LuthR stock, AAc mini can, NF SHV F1 scope, Geissele 15 inch rail, G SSA trigger, rattle can paint job bla bla bla and his is the same all by coincidence. But for this thread, Geissele rail is the take away.

20” Krieger barrel
VLTOR MUR upper
Noveske lower
Geissele SSA-E.
I think it’s a MkV Rail? 15” for sure though.
BCM BCG & CH

600 yard movers. I like the Geissele because I can put a lot of pressure on it and not have much shift on the laser. A KMR did not work well for this purpose. I also quite literally beat the shit out of it.

I too like their ruggedness. Just good solid rails. I have the original first gen rails and have their rails with 3-6-9 pic rail attached. I forget the nomenclature . All their stuff has been good. Guns are similar but I don't have those baddas moving targets. That shit is sweet.

Euro did you change to PRS stock and longer barrel? Or is my memory gone? Nice pig!

[Jsp10477]

Geissele. I have a 20” similar to Euro’s with a 15” Mk2, an 18” SPR with a Mk4, 2 16” recces with mk2 and mk4 also. IMO the Mk2’s are more rigid but they are discontinued.

Nah man I’ve had a 20” and PRS since that thing was built years ago. I know you desert guys like to show off your long distance with short barrels but I needed the extra length to get me through our hurricanes. :)

I have a 15 inch aero precision on mine. May upgrade one day but it works fine for what it does.https://uploads.tapatalk-cdn.com/20190107/c22bbeea1b0457e6ea4afdfd77bc62e7.jpg

My SPR started out as a MK12 mod0 clone. I modernized it a few years ago to make it less bulky. Im using a KAC URX4 rail.

It’s been performing great. I love this rifle.

Thinking of changing it up

Thoughts on putting a 13" rail on a 16" Reece build that will have an aac m4-2000 suppressor? As opposed to a 15" rail?

[Eurodriver]

Nothing wrong with that. Get a 13” Geissele. :)

[snackgunner]

Exactly what I'm going to do.

Think I'm going to pick up a G mk8 13" :)

[Cretin]

We run Geissele MK 8 on my ADM team. You can’t go wrong as long as it’s a quality brand, however.

[drtywk]

I run a 15" Centurion Arms MLOK CMR on my 16" Recce build and a 12" BCM QRF on my MK12 inspired build. Both are excellent and priced competitively.

[Endur]

13" KMR on mine but will eventually be replaced with its MLOK counter part.

Everything I’m shooting now is KAC, so I’m all about the URX4 M-Lok. Any of my non KAC guns are wearing Geiselle though.
