Scott S from United States, NJ Public Profile

Replaced a carbine collapsible stock with this because I have a long length of pull. With the 1" recoil pad I gain about 1.5". Trick is getting the foam tube on the buffer tube. I used a few drops of dish soap and badd bing.

My complaint with the stock Sig 516 is the forward weight of the firearm... it's forward heavy, not balanced.

This thing is fantastic. When mounted It feels great in the hand. The carbon fiber, fit and finish is quality stuff. It's not substantially lighter than the stock Sig 516 Patrol picatinny rail grip. What is does extremely well, is re-distribute the weight aft, i.e. moves the CG (center of gravity) back to the mag well.

Having replaced the handguard, buttstock and buffer. The latter a Doublestar Skelton ARFX and JP Silent Capture Spring. The net effect with a Vortex Viper PST 1-4x24 scope, yields a firearm which in the hand is supremely well balanced. The CG is centered on the mag well just slight behind the breach. It no longer feels like I'm trying to aim a one ended dumbbell.

I'd have clicked 6 out of 5 stars were the screw hardware not garbage and complete with all necessary screws. The unit ships without the two screws that secure for locking lug seating on the barrel nut. The stock handguard on a Sig 516 Patrol uses two longer counter sunk screws. This unit requires shorter caphead screws. The real gripe is the cheap metal screws that secure the upper to the lower halves together. The hex heads strip like made of silly putty.

That said, in the end, despite the inconvenience of replacing some screws. I'm totally pleased with the my purchase. I hope my complaint about the screws gets attention.

At 6'4 my long arms like a long length-of-pull (LoP). The Magpul PRS Gen 3 brings balance to my billet upper and lower which are coupled with an 18" .308 cal barrel. With the Magpul extra thick pad, LOP stretches out to 16.5 inches. On my bolt action rifle I like having the centerline of my scope being as close to the centerline of the barrel as possible. But on my AR's I prefer a bit higher.

Originally I purchased another manufacturer's stock which with extensions reached about 15.5 inches. But I ended up struggling with the weight (too light) and adjustability. The first guy's stock required being taken apart to some extent to adjust pull and cheek weld and it was clumsy in process.

The PRS is easy to adjust, which I like when changing shooting positions. I'm not a competition shooter (maybe someday), But I do like to practice from different positions and the ease of making changes is very convenient. That and the fact the weight brings a nicer balance to my large frame build.

That said, the expense. This stock cost almost twice as much as the other guy's. This stock offers value, butt....

In the end I have a rifle with about $400 invested in buttstock.... Lesson learned. But I am glad I have this stock. Much better than the other guy's.
