Hey guys, I'm kind of new to msr weapons . I am running a carbine length extension right now . I am wanting to install a Magpul PRS which is recommended using rifle length extension. My question is,will I run into any problems with function of weapon with current loads? Any suggestions? I am running a 22" 1-8", 4groove Thanks ,Phil

no the mongoose runs just fine with rifle spring and buffer set up. when you change from carbine to rifle you need change the buffer tube, spring and buffer fyi you can't run the carbine stuff in the rifle set up.

Thanks BIGGDAWG . I really like this Mongoose ! I am getting exceptional accuracy out of this setup. Just needing to get away from the collapsible stock,not very good shooting off of bags . Thanks again !

I love either the lightest buffer (with adjustable gas block) or the heaviest buffer (with or without an adjustable gas block).

Lightest .. Taccom3g (.com)
Heaviest .. Heavybuffers (.com)

[Adjustable gas blocks .. I like SLR clamp-on & I love BRT pin-able gas blocks (adjustable and non-adjustable).]

Ditto BD's endorsement for the Luth-AR.  I have several MagPul and GI (both A1 & A2) rifle stocks... the Luth-AR is really nice!

There certainly is a $$ difference between Luth-Ar and Magpul lol . Does the Luth-ar stock allow for vertical and horizontal adjustment of shoulder pad? I did notice that Luth-Ar does have a collapsible stock version as well . I run a few different uppers on this particular lower , .300 BO With carbine gas, .30 Herrett AR with mid gas ,and a .556 with rifle gas . I guess I'm wanting to know if I change to a rifle extension ,spring & buffer will my other uppers function properly. Sorry guys,I'm learning here lol 😵

I'm partial to the BCM stocks .. though I own a lot of different MagPul ones. My only A2's are on my national match AR's.

if the gas system is set up right on the other rounds they should run fine with the rifle set up.  another thing to look at is the vtab i have 2 i just got to put on my luth ar stocks very neat device http://www.anarchyoutdoors.com/v-tab-u-verticle-tactical-adjustable-stock-pad-fits-magpul-prs2-rpr-luth-ar1-3/

Thanks for the links BIGGDOG ! I think I am going to get one of the LUTH-AR carbine stocks. It appears it will ride the rear bag better than my Magpul STR. Just keep my carbine buffer and tube . Thanks 6MMTCU

6mmtcu .. BiggDawg is right ..

But if you are like me and you run supers and subs with and without a suppressor .. running a non-adjustable gas-block could make you run different buffers and springs. Or risk an even more over-gassed rifle.

Unless you get BRT to tune your gas-block port you will probably do a lot more adjustments with the buffers and springs. He did a great job on my 6.8x43 pistol gas block. (Personally adjusted non-adjustable pinned gas-block .. you have to remove it to adjust it with inserts.)

IMHO adjustable gas-blocks are worth the money for anyone running suppressed and un-suppressed with varying loads / weight bullets in the same rifle.

As always .. free advice is worth what you pay for it .. heh.

Lots of GOOD free advice to be had here. I value it greatly.

Thanks Honeycomb ! I currently don't run an adjustable gas block . Maybe I should check into it,does make sense to be able to tune your rifle to your loads . What would be some good agb to look at?

Like BiggDawg said .. SLR is my go to adjustable gas block. You will get a flatter shooting rifle (i.e. less muzzle jump) .. with less wear and tear on your components and brass.
