CASEYPM Posted September 4, 2015 Report Posted September 4, 2015 I just finished my first black rifle build. I chose the PSA PA-10 for the awesome price. I completed it for only $750. I bought the upper, lower, LPK from PSA, $94 barrel from Anderson and bcg from radical firearms. Got the mid-length gas tube from a local black rifle shop and had a slight problem. The gas tube was exactly 5/16" too short and short cycling is common for their rifle due to this because the tube is too short they sell and tell customers to buy. Fortunately I discovered it before I was finished and bought an armalite AR-10 carbine length tube that is 12--1/16" which is 5/16" longer. Apparently they cannot tell customers to buy this one because of copyright reasons from armalite. Now that's customer service... So hopefully you're reading this first before you buy the wrong tube. Here's some pics of both.
CASEYPM Posted September 4, 2015 Author Report Posted September 4, 2015 Here's another pic from someone that bought a complete PA-10 not long ago. This confirmed that it wasn't a beginner's mistake on my part.
survivalshop Posted September 4, 2015 Report Posted September 4, 2015 Just shows PSA are beginners . LOL
washguy Posted September 4, 2015 Report Posted September 4, 2015 Just shows PSA are beginners . LOL Yep they are ! but they do make fine bench guns..... ya beat em on the bench..then put em under the bench, and pull out a rifle that works ! Wash
Magwa Posted September 5, 2015 Report Posted September 5, 2015 I do not know about their 308 platform but they have some good 5.56 stuff for good prices have built several and never had a problem and thousands of rounds thru them...

GreyGoose Posted September 5, 2015 Report Posted September 5, 2015 Well they make absolutely nothing, so ya the factory gun parts with the PSA stamped on the side should run fine, if the customer service from PSA is adequate enough to support it.
Kelly Corean Posted October 20, 2015 Report Posted October 20, 2015 CaseyPMJust starting my first 308 build and I bought the complete PSA lower assembly off their scratch and dent sale and it appears absolutely perfect to me as far as finish and all the bits and pieces properly installed in the lower. (At least from my AR15 builder eyes...) Included what appears to be the correct short 308 buffer and a stiff buffer spring so I "think" I'm good to go there. I have one of their blemished 308 uppers in the mail now.So now to decide on a BCG and barrel - from your experience can I use any DPMS patterned BCG and barrel? I'm leaning towards the Faxon 18 inch barrels. And to answer the PRIMARY question - truck gun for heavier game (i.e. elk) and I hunt in mountains and I'm so want to keep the weight down as well.And thank you in advance.KC
Kelly Corean Posted October 20, 2015 Report Posted October 20, 2015 One other question - DPMS 308 mid-length gas tubes are 11.75 inches? And the PSA tube is shorter than that?
Magwa Posted October 20, 2015 Report Posted October 20, 2015 If weight is your goal (and it was mine) 16 inch barrel and everything else as light and small as you can get I have killed 2 elk and 5 deer with mine and empty it weighs a bit over 8 lbs...
survivalshop Posted October 21, 2015 Report Posted October 21, 2015 (edited) I agree , a 16" rifle will be less weight ( depending on the Barrel of course ) & is quicker to bring up or swing .You will not lose much down range , my 16" is very close to my 20 " @ 200 yards ( far as I have range to shoot ) Trigger makes a big difference , where the MechArmor Trigger in the 16"is an great single stage trigger , the Geissele SSA , two stage ,I have in the 20" is much more suited for the target range , as is the rifle itself , Heavy , not something I would think would be a good brush gun ?. What stock system are you going to use ? Short Buffer sounds like a Carbine Buffer .Measure the length of the Buffer & spring , count the coils on the spring & weigh the Buffer One other question - DPMS 308 mid-length gas tubes are 11.75 inches? And the PSA tube is shorter than that?No idea what PSA is using , the AR 10 gas tube worked with that barrel configuration shown above , not sure how Tolerance stacking of the PSA Receivers will compare to DPMS components or the Faxon Barrel . You will not know for sure ,till you mock the system up, unfortunately . I have Full length gas systems on all three of my 308AR's , all barrels are Criterion , 16",18" & 20", I have yet to do testing at 200 yards with the 18" & will compare all three with the same ammo( s ) after the Holidays .

Kelly Corean Posted October 21, 2015 Report Posted October 21, 2015 Thank you very much for the good info.KC
Kelly Corean Posted November 13, 2015 Report Posted November 13, 2015 Just a note to those looking for the AR-10 mid length gas tube -- Cheaper Than Dirt has them listed as:LBE Unlimited AR-10 Mid Length Gas Tube Stainless Steel ARGT308 for $16.49
