Re: How Critical Is Sight Base Alignment With Bore?
Received The 3 LaRue QD Risers back in today's mail.
LaRue did reimburse my shipping costs which was decent of them...
There was no letter or indication that the gear was checked out by anyone. Their phone receptionist handles returns for the company, after conferring with the sales mgr. Not really what you might expect of a company that has "precision" in their corporate name.
No note saying "We checked these products and found them to be within our technical specifications", etc. People have bitched repeatedly about Remington chambers and poor accuracy along with other mfrs crummy products being "within production specification".
Did get a yellow sheet dtailing LaRue's "If you ain't happy, we ain't happy return policy" which states they have a "Lifetime guarantee on defective parts"...
Interesting opportunity here.
I did remount the Leupold Mk4 1.5-5x on med 30mm rings and shoot a few rounds with my AR-15 over the weekend. Used the Brownells ring alignment spuds to assure that detail, then boresighted using bushnell collimator. Just confirming on-target at 25yds in my yard; was on target w/first round.
Will remount scope to each LaRue LT 110 and fire at 25yds to see if there is any change in point of impact.
Doesn't matter? "Just use the base and go shooting"
Wonder if the Weaver and other scopes used on the Garand sniper rifles were specifically matched, made-for the offset mounts?
No modern scope I'm aware of is designed to be used Off-Axis. Even a side-mount like a Sadlak M-14 mount which I have owned is designed to place scope in-line with the bore, not offset to bore like the LaRue riser and likely all their other QD products.
Anyway, will see if there is impact shift at 25yds and maybe at 100.
If product is designed without concern to off-axis alignment, guess it ain't "defective" if customer discovers this to be the case. Their design errors and lack of awareness as to what precision means in application to centerfire riflery speaks volumes.
