My order processed and was out for delivery super fast, but then I got a notice of a delay in transit from FedEx before Christmas. Then we had a snow storm in WA State and that caused even more delays. It ended up being almost a week from notice of shipping to having it delivered. Not really that long of a time to wait, really, but was about four days later than initially scheduled.
I have a PRS Gen 3 on my AR10. I recently got a PRS Lite for Christmas and I really like it. Set it and forget it. Its a ton lighter than the Gen 3 PRS.
reminds me of the PKM stock a little bit. one gripe I have is the bolt hole to adjust the cheek riser is at a strange angle even with the stock extended all the way. But like I said before "set it and forget it". honestly 9/10 would buy.

Thanks. That's what I needed to know. the Magpul PRS Gen 3 stock L.O.P. on my Ruger Precision Rifle was 15-1/8" at the shortest setting and 16-9/16" at the longest setting when I first installed it. I had to cut 2" off the front of the stock and 1-1/2" off the back of the receiver extension to get it in the usable range for me.
I'll have to look for another option.
The ACS-L seems to work perfectly for me on my PA10 with 1.5" scope mount. My eye lines up perfectly so I don't need an adjustable cheek riser and the length of pull can be set as short as I want.
The small storage compartment comes in handy for stashing the allen wrenches that are nice to have access to for making sure things stay tight.
Would anyone measure the LOP with this stock in the shortest configuration. The Seekins 10x stock measures nearly 15”. The PRS Gen3 is 14 3/8”. Manufacturer specs don’t seem to be close. Any help would be appreciated.
Thanks. Magpul’s published specs are fairly close then. Guys shoot their bolt guns with relatively short length of pulls but that isn’t an option with a semi auto and a rifle length receiver extension it seems and this stock is probably too long for many mounted on a a5 or carbine length. This stock is about at my max. I may end up going with the UBR. Thanks for the confirmation.
The UBR has the receiver extension in it already. Are you taking that into account? I know the UBR Gen2 from what I’ve read were lightened considerably.
Which is why I can't understand why they made it so long.
It would appear the PRS Gen3 LOP is 1-1/4" longer on the RPR. I could have lived with 13-7/8".
I run mine on the VLTOR a5 tube.. in the minimum setting, guess I got lucky that LOP is dead-on for me in that fashion.
Excuse my ignorance, but do you not need an end plate and castle nut when using the UBR?Magpul PRS lite + Vltor A5 buffer tube + end-plate + castle nut = 1 pound, 8.2 ounces.
Mapul UBR Gen 1 + buffer tube = 1 pound, 10.1 ounces.
....
An endplate and castle nut are not used on the UBR gen 1. It has a carbine-length buffer tube that screws onto the lower receiver just like a rifle length buffer tube.

In case anyone is interested...
UBR Gen2
weight - 21.2 oz (with receiver extension and storage compartment installed)
LOP - 11.8" collapsed
15.3" extended

Thanks for the specifics. I tried the UBR Gen 2 as well but it was too heavy for me for a "combat rifle", which is weird..as its supposed to be the "ultimate battle rifle" stock.
I went back to back with a magpul CTR stock and remember thinking that the impressive ergonomics of the UBR just cannot make you forget how heavy the thing is..and that was on a 16" rifle with a slim handguard and no optics installed yet.
I use the UBR Gen 2 but it's on an 18" barreled PTR91 GI which is a heavy beast already.
took a few pics in case it helps anyone here. One thing to note for KAC owners, sorry if its been covered already. Due to the KAC hardware thickness if you go with the PRS Lite it will leave a gap and expose threads on the buffer tube. The pic (SR15) with no gap is taking the KAC hardware off and throwing on a base plate and mil-spec castle nut.
any questions let me know, hope this helps.

I only had it on the non KAC hardware picture, but if I add it to the KAC hardware pic, it just bumps the offset out and the gap is the same.
Gotcha. Reason I was asking, KAC sized that castle nut for their proprietary QD end plate (hence the spanner inteface instead of a GI castle nut interface), it works out to the same thickness as a GI nut and plate more or less (~0.535"). If you run that setup, the quick math is to bob a PRS3 or PRS Lite front cap back so its flush, then it will fit the factory KAC setup with their QD plate.
Obviously, there are a lot of different end plates and a few different castle nuts out there and they're different enough you can't comp for them all. The keyway on the receiver extension is what keeps it from rotating, and the cross bolt keeps it from sliding back so mechanically it won't hurt anything to trim up the front if you need to.

that makes sense, this SR came with the QD endplate which is much thicker, almost flush to the castle nut. I have spare prs 3 parts but can’t get them to work with the prs lite. May be messing something up but there is a tab on the front of the lite that doesn’t allow the prs 3 adapter to fit. The prs adapter (3) also seems to attach different and be a little wider than the Lite(L).

Just to update, Magpul processed my warranty return and sent me a new stock, no fuss, no muss... Didn't even call me a tard for breaking the first one. I got the new one mounted on my 6ARC and out to the long range this past weekend, definitely a lot of stock for the money, I'm sure there will be more in my future.
My cheek piece has some wobble to it also but not too bad, I think it's just inherent in the design where the actual riser connection is in the back so the front has some play. Otherwise, it locks up solid and I'd characterize it as set it and forget it but I'm digging it on my SPR, a great stock for that application.
I'm still waiting on one also. Optics planet says it's supposed to ship sometime in April lol. The FDE version

I picked up a couple from brownells. I haven't had a chance to mess with it much but my first impressions are good.
My only dislike so far is the buttpad. I really got spoiled with the limbsaver pad on an STR I had. And if anyone is wondering, the extended gen3 prs buttpad does not fit the prs lite.

I have thought about getting one. A question to the current owners, can the cheek rest come off and it be used without it or would it leave some type of a gap or hole someplace. I have not seen one up close as of yet.
Thanks.
Thanks.
Good question. Here’s what it looks like.
Right! It is not a recoil pad…just hard plastic. If anybody finds a real recoil pad that fits, I’ll buy one.
Thanks for posting the pic. That answers my question very well.
Thanks again
Thanks again
Could you elaborate or post pics of why the Gen 3 does not fit?
Truthfully, I’m more curious if the Lite recoil pad fits the Gen 3? I was hoping one of the new products’ recoil pads would fit but Magpul hasn’t been helpful in answering that question.
You can attach the gen3 pad to the lite stock. But the two are different in size. The lite pad is wider and I believe the height is slightly off as well. I will snap a pic later so you can see what I'm talking about.
Gen3 pad laid on top of the lite pad. The lite pad is wider and a little taller.

Wow, im glad i read this thread. nearly 14" as a minimum is ridiculous
Thank you for the pictures, however, I’m fairly certain that is a Gen 2 PRS extended pad.
My Gen 3 PRS is much more similar to the Lite. I just don’t know if it’s similar enough to actually be interchangeable.
I see. Can anyone point me to the recoil pad for the prs gen 3 please. I cannot find one on their site. The part number of the one I have is MAG350 PRS Extended buttpad.
Thank you! Now I just need to figure out how to get Magpul to sell me one so I don’t have to pay $119 for a recoil pad.
There currently is not an option to buy them individually. That’s where I’m at in my search for the Lite pad.
Well if I find something to replace my lite pad, I'll have 2 of the factory lite pads if u want one.
