DPMS LR308 Upper Receiver/Lower Receiver Play

[KS Shooter]

Guys,

I have a new DPMS AP4 and am considering changing to a new LR308 with 24 inch stainless barrel.  My question, is, is there supposed to be considerable play between the upper and lower receivers?  I checked the play between the two receivers at the local dealer and it is more than my AP4.  Should there be this much play?  Will it affect accuracy?  Should I stay witht the AP4?

I reload and am making match ammunition (right now 168 gr. bthp) for shooting target.  If I stay with the AP4 can you recommend a good scope?  How about for the LR308 (24 inch barrel)?

thanks for the comments in advance!

Most like the receiver fit to be on the snug side . I have only one AR that is on that side , the rest have some play.( including my 308"s )

The long range shooters may speak up ,but I have not found a difference between tight & loose or some play as far as how they shoot ,but I have never done anything as far scientific testing .

The beauty of the AR system is that every thing that needs to be aliened is on the upper receiver ,so it really shouldn't matter.

You can get matched sets of uppers & lowers ,I have one I built from Olympic Arms that is well over twenty years young . Its an odd ball build as most see now a days , she has a Ultra match ,24" ,1-10 bbl..( this one has a small amount of play )

Non of my 5.56 AR's have Flat top receivers , they are too old for them new fangled things ,but the 24 " is as good as it gets a 100 yds. with Iron sights. I guess at my age ,I should put a scope on her & try it out.

Scope choice, well there are so many out there ,just how much do you want to spend?

survivalshop,

thanks for the information.  I was looking at spending less than $500.  I am leaning towards a wotac scope when available and I have the money.

DPMS makes an item called 'The Wedge' to help eliminate that play but I'm not sure if it works here, or only on the AR-15.  I guess theres no reason it wouldnt work.  I asked DPMS this same question but they have not got back to me.    Anyone else familiar with this item?

Fulton Armory lists the Accu Wedge on the 308 Titan Pages

The Millett TRS-1 4-16x seems to be a decent scope for the money. I have one on my LR-308 and a couple hundred rounds on it, so far pretty good scope.

I'm gonna try the one from Fulton Armory in my DPMS LR-308.

Try grouping , before & after install , to see if it does anything in the way of accuracy  & let us know .  Thanks.
