I want to buy a complete lower from spikes tactical but im not sure where to have the stock pinned, is there any way to guesstimate where to have it pinned? im a small guy and a fully extended stock is too much. any help?

I perfer it at the max. go to a local gun shop and try one that isn't pinned yet.

The full length isn't a bad choice really. I have a small wing span myself, so I feel your pain. In my experience, keeping the stock pinned at its full extension forces you to maintain a good position-- but its really a preference thing. Retractable stocks were made to accommodate body armor and CQB and SBRs (though I think that last one is more of a "New Age" thing).

 

Your best bet is to do what TJ said, and that's find a stock that hasn't been pinned yet at a store. Or you could always call the company and ask what the length for each pull is (or Google it), and compare that to what you would prefer.

thanks guys quick and helpful

IMHO, the position you decide to pin it at should largely depend on your body position while shooting standing. If you shoot "squared up" for example, a full extended stock will probably feel awkward, especially if you have shorter arms. If you shoot very bladed (body turned at an angle) then a longer length of pull may be more appropriate.

 

If you can't get to try out different lengths, my suggestion would be to find what an A1 stock's length of pull is and have the stock pinned to that length.

 

And, just for reference, I'm about 5'11" with longish arms. One of my ARs has a Sully stock which is basically the same LOP as a collapsible stock one click out from fully closed. My other AR has a MOE stock that was pinned at the 2nd click out from fully closed if I remember correctly... which is approximately the same length as an A1 stock. Both lengths work for me and how I shoot.

 

In the end, stock length, like almost everything in the AR world, is very subjective

 

Good luck
