Geissele Cut Rifled SPR Build and Barrel Evaluation. (Part 4 (Load Development 28MAY25) Update!!!

Hello Snipershide! Geissele Automatics has been offering Single Point Cut Rifled Barrels for close to two years now but they've been restricted to the 6 ARC Stratomatch or blanks that the end customer could have custom turned from barrel manufacturers like White Oak Armory. Two weeks ago...

Now I see what y'all are talking about I didn't know they had a earlier model without the anti-rotation tabs machined in the upper for the handguard.

All of mine are the M89, as shown in this build review. I've got 4 or 5 now and I'm extremely impressed with the quality and rigidity.

I have 3 of the M89 rails and I like them a lot as well. FWIW I think the OEM for the rails is Hodge Defense.

Hodge may have designed the lockup, but doesn't manufacture anything.
.Pretty sure they're Mega/Zev

If anyone can't find a broadsword upper but wants to mount a SOLGW L89/M89, another option is the billet flared upper from Icon defense. The finish/lines precisely match the l89 handguard (another reason I think they're both produced by mega/Zev), plus it has the advantage of matching the lines of a mil-spec lower better than the broadsword does.
And to top it off, it's cheaper.

What grip is on the lower? I like how vertical it is.

Icon is making all of SOLGW uppers/lowers. Mike mentioned that it was different machines than Mega
