Does the cheek piece when raised have enough clearance for the charging handle? I have wanted one for a while but I wasn't sure about that.

Hello all, forgive me if this has already been answered in another thread. I was wondering what tool is the best to use on the locking ring that comes on DPMS free float aluminum handguards. I have 2 different DPMS uppers that are different heights and I want to swap out the barrels/handguards. I have the barrel nut wrench, don't have any type of spanner wrench or a skinny enough strap wrench to fit that little ring. Here is a crappy non-smart phone pic of the ring. Thanks.

wow, didn't expect a reply on this one! (old thread) I actually bought a DPMS .243 upper since my last post, and it is the newer (lower) height receiver. I planned on taking off the standard free float tube to put on a vtac tube anyway, so I decided I'm going to swap receivers / barrels around while I'm doing it. Putting the lower height upper receiver mated with the AP4 barrel and lower height handgaurd should work out fine. My .243 setup will be sporting a scope at all times, so the height difference won't matter to me anyway. Thanks!

I measured and it is an older height upper for sure. I still can't understand how .05" would make much difference. Not the end of the world. I have the rfile zeroed at 50 with my post higher than the wings. I might buy a new upper to match the handguard rail height, put on a different gas block and put matching front and rear buis on it. I can use the removed upper on that .243 build I have been contemplating.

I need to measure, but I'm positive I have the old receiver height and a newer free float rail. Both are DPMS. I bought the rifle less than a year ago, but I think it was old stock because it had the A2 rear sight instead of a carry handle A2. When I bought the handguard the newer rifles had been out for a while.

I bought the railed handgaurd and had it put on, you can see that the rail is lower than the one on my receiver. I'm not opposed to a flip front buis and a different gas block if it will solve my problem. I just hope the difference in height between the two rails doesn't affect much.

It was bought new as a complete rifle, both halfs are DPMS. It does have a slight hairline gap there but the photo shadowing makes it look worse.

thanks, I'll do some research on it. <thumbsup>

1. The sight has markings, but I cant tell what they are. 2. I am forced to do a harsh 6 O'clock hold or jack my sight post way up above the "wings" on the front sight. 3.

it is the DPMS A2 style adjustable rear sight (freestanding, not part of a carry handle) and I have it bottomed out. Using the small peep probably wont help me because it is on a different focal plane for distances past 200, and would just make it seem worse. I also have a fancy pants A.R.M.S. flip rear and the results are the same. The newer AP4's come with a carry handle setup, and mine has the older freestanding sight. This makes me wonder if the reciever height is too high and that's why they later changed specs. Would .06" make that much of a difference on my sighting? Can I get a taller gas block A2? Is there any other factors that could weigh in on this?

Hello all, I have a DPMS LR308 AP4 and I am baffled about my issues using the iron sights. The rifle is very accurate, but it seems that my rear aperature is too high (and yes, I am using the large 0 - 200 hole). I have to bury the front sight into the bottom 1/4th of the sight picture to get point of aim / point of impact close at 50 yards. Aiming like I should be able to, it hits 6 inches high at 50. I have a bushnell holosight (eotech clone) on it and it does great without using irons. I even try using the dot as a reference point for aligning my front and rear, but it seems the rear sight is too high for practical use with the fixed front A2. I could crank the front post way up above the "wings" to make it up, but that is just silly and I would probably catch the post on something and bend it. Anyone had similar problems? By the way, I have also put other rear sights on and they all seem to be the same height.

Thanks.

My Dad is looking to buy a lower to match with a 7.62X39 DPMS upper he just bought. The guy he bought it from says he will build him one from a stripped CMMG lower with DPMS guts and collapsable stock for a really good price. How good are CMMG lowers? Will he get a nice fit with the DPMS upper? I'm just excited to get it to the range with him when we track down a suitable lower! <thumbsup>
