Sparrow Dynamics Compliant Rifle Grip - Official Discussion

[Sparrow Dynamics]

Hello Calguns community! Thank you for visiting the official discussion thread for the Sparrow Dynamics Compliant Rifle Grip. I messed up and had some discussion happening in the marketplace. This thread is linked from our commercial sales thread. All comments and questions should happen here instead.

We designed our grip to be very comfortable AND look like it belongs on a modern sporting AR-15. It is similar quality to Magpul furniture and we think it looks great and functions better. Hope you agree!

60 or 90 degree throws and our levers can be set in 6 different positions so you can find your optimum featureless configuration.







From our website:
Our ambidextrous safety selector is a superior drop-in replacement for all mil-spec safeties (AR platform 5.56 & 7.62) and is meticulously machined from the finest materials to provide the smoothest operation and a crisp positive feedback. The levers are machined from 7075 aluminum and are hard coat anodize (available in 4 different colors) after a heavy acid etch process which dulls the machined surface and provides a superior protective finish. The core or shaft is 416 stainless steel which is highly corrosion resistant and very strong. Our unique lobular interface between the lever and the shaft provides a solid connection and allows the lever to be installed in 6 different positions (not just two like other safeties) for the the ultimate experience in user customization. The engraved markings on the shaft simplify the installation of the 60 or 90 degree throw options. Quality USA made wrench included (not shown).

Previous discussion brought over from the marketplace thread. = cleanup

Are these hollow?

Good question. Yes, they are hollow, very similar to Magpul's grips. Same strength and wall thickness with some ribs inside. We are also working on an insert for it for stuff like extra rounds, or bolt, firing pin, etc.

I'll try to get more photos showing that after Thanksgiving.

Work on an aero 308?

Will they work with an A2 buttstock? Is there enough clearance to keep them compliant and not risk becoming a "thumbhole"?

They will fit on a 308 lower, but won't be usable with your thumb over the top. Although you can still use it similar to how you would a Monsterman grip with your thumb to one side. I'll try to add a photo showing that soon.

I think there is enough space so that the A2 stock won't touch the grip (causing a "thumbhole" situation), but I will need to confirm that for you early next week.
C.W.M.V. has a valid point. If I understand correctly. I will point out, that if the grip ends up not interfering with the A2 stock (which I will confirm for you), you WILL NOT be able to get your thumb over the top of the grip. Although you could still use it similar to how you would a Monsterman grip with your thumb to one side. I'll try to add a photo showing that soon. BUT, if you are using an A2 stock, maybe a Monsterman would blend better. It is a nice grip for that configuration.

P.S. It does work well with the Magpul fixed stock.

My thoughts:

The texturing on the grip is nice. Grippy but not rough.

The angle of the bottom of the grip is great.

The grip reminds me of a cross between the Liberal grip and a Hammerhead with a little bit of Monsterman thrown in. I like it a lot.

The grip fits really tightly on the lower (at least it did on mine). I had to gently tap it in place with a mallet.

The blob of threadlocker on the grip screw (I'm assuming that's what it was) may be a little heavy. I had a hard time screwing it in all the way.

Overall great grip. Ordered another one for my father in law.

[Sparrow Dynamics]

Fantastic! Thanks for the feedback trackhazard!
I see you also wrote the full review here with a photo. NICE!
trackhazard's review

I'll look into the threadlocker. I originally wasn't going to include the threadlock patch and just let people add their own, but I thought it would be nice not to have to worry about not having loctite.

The tight fit is tricky. We let them cool on a jig for 8 hours so the plastic doesn't shrink in. The jig size is very exact, so that the grip fits nicely on a receiver that is .375 thick, and doesn't fit too loose on an undersized receiver (like a Spikes Tactical that I have). But, if your receiver is oversized, it will be a bit tight. We were shooting for a happy medium, and I think most people will be right in there.

We really like how the laser texture came out. Some day I'll post a video of the laser engraving the mold tool. It is memorizing to watch.

When do expect to have black grips back in stock?

Inventory is fixed now. We have plenty in stock. The website inventory just wasn't updated when we received our last shipment.

[C.W.M.V.]

Two on the way!

[AregularGuy]

One on the way. I appreciate the discount and code. With tax and shipping it was just about $40. I feel like that's a bit steep for a grip9 but I understand it's a new product and probably not much more expensive than some of the other options. Of course no one is twisting my arm to buy it. Can't you ship via usps for cheaper than $7.95? Thanks again.

Ordered, thanks!

Will fit on a SCAR?

I'm curious if you have it set up as featureless why does it appear in the pics to not have a standard mag release?
