Dear M4C,
To begin, I am a long-time lurker who (very) seldom posts. I've learned quite a bit from this site and am hoping someone here will be able to answer my question. I have previously tried Google and the M4C search engine, but no luck So here goes:
I am assembling an AR upper receiver group. Intended purpose is to shoot targets at the range, but I also wanted as quality and reliable a build as was possible. To that end, I purchased a LaRue Stealth Billet LT-007 A3 upper receiver to go with my (previously purchased) Green Mountain HBAR 20" barrel (I live in an AWB state); at the height of the pandemic the LaRue was the only upper receiver I could find that had rifle extension cuts (the Green Mountain barrel necessitated that feature) and from what I read, LaRue is a very well-respected company in the AR world (to say the least). In retrospect, perhaps I should have purchased a different barrel with M4 extensions, but this is where I am.
At this point in the build, I am searching for free float rail to mount on the rifle. I happened across an 18" Midwest Industries Combat 18" rail (MI-CRM17XR). (I am thinking of putting a bipod, hence the longer rail). However, there is a disclaimer on the MI webpage:
"IMPORTANT COMPATIBILTY NOTES!
Due to the many different dimensions in BILLET UPPER RECEIVERS on the market, please contact your billet upper receiver manufacture to insure fit of this handguard. This handguard is compatible with standard forged upper receivers."
Well, I contacted LaRue as MI suggested, but LaRue had not actually attempted to install this rail on to one of their LT-007 A3 upper, which isn't surprising (I mean, why would they?).
So anyway, not to belabor this any further, does anyone here have any experience mating the LaRue upper receiver described with the MI Combat rail? Any and all help is much appreciated. Thank you in advance.
Regards,
