Tex's First Grendel Build - 18" Piston SPR
#21
So... I completely forgot to follow up on this thread. Rolleyes

The first time I took her out, I was not impressed with the piston action. Even when adjusted to minimal gas, cycling was a jolt, making follow up shots difficult. Probably a combination of heavier bullet than the .223 and the heavy side charger carrier. I swapped in an adjustable Master of Arms titanium gas block.
Next, I had some issues seeing through the FFP scope. My eyes are aging and the new reticle on the CMR-8 is cluttered compared to the old, simple one. I swapped that out for a 2-7x Leupold.
Also, while I love the original rifle stock, it wouldn't fit in my favorite 2-gun carry bag. That stock got swapped out for a FAB Defense GL-Shock stock I had lying around which put the balance point exactly at the sidecharger charging handle - the point of balance of a full or empty mag. Perfect. In the beauty shot, the rifle is balancing on the charging handle.
I've been out to the range a number of times and it's a tack driver with Hornady 123gr BTHP. I've included a shot of what it does with 100gr Wolf at 50 (3 shots on target) and 100 yds (7 shots on target) a couple of days ago. I had planned to spend more time with the Grendel, but spent all afternoon trying to sight in a troublesome .22 rifle which under closer inspection had a stripped screw on one of its scope rings. AAAAARRRRRRRGH!

I love this Grendel. It's set to shoot ~3.3" high at 100yds for an 8" MPBR of ~290yds.

If I remember, I'll update soon with some better groups with better bullets.
