dkreutsberg Posted August 22, 2015 Report Share Posted August 22, 2015 I will be attempting to mate a PSA 308 upper to a 308 Rainier 20" match barrel; however I'm not sure whether the bcg should come from Palmetto or Rainier! Any thoughts Quote Link to comment Share on other sites More sharing options...
Malig8r Posted August 22, 2015 Report Share Posted August 22, 2015 If you purchase the barrel and bcg from Rainier Arms, they will headspace the bolt and the barrel for you. I would go that route. Quote Link to comment Share on other sites More sharing options...

Any thoughtsThanks! it seemed like the smart thing to do but I wasn't sure if because of PSA's compatablity issues that it might be prudent to get everthing in the upper from them. Unless I trash the upper. Quote Link to comment Share on other sites More sharing options...

98Z5V Posted August 23, 2015 Report Share Posted August 23, 2015 That's good - keep 'em together from the same manufacturer, in this build-game. Whatever weird, proprietary parts that PSA has for their upper and lower sets, get those. Everything else shouldn't matter. Run an Armalite buffer system if you'll be building a collapsible stock. I've found that there can be issues trying to mix "x" carbine receiver extension with someone else's cheap "DPMS LR308 carbine buffer - compatible" and so forth. With a 20" barrel, will you be running a rifle stock and not collapsible? Quote Link to comment Share on other sites More sharing options...

I'm going to try using a Rainier bcg after having Rainier match bolt to my barrel. Not sure of fore end yet as I'm waiting for clarification from PSA on whether this receiver is high or low profile, because the rear tab at the charging handle is 3/16" which is supposed to be high but I read another thread that quoted PSA as saying their recievers take low profile handguards, ????????

98Z5V Posted August 24, 2015 Report Share Posted August 24, 2015 Match it off the rear tab on your upper receiver... If you measure it out and it's high profile based on the measurements, then get a high-profile compatible rail or handguard system. Quote Link to comment Share on other sites More sharing options...

Comes with the ACT relatively inexpensive, standard pull weight trigger group, MILSPEC but polished and coated, akin to the spikes battle trigger group.

392heminut Posted August 25, 2015 Report Share Posted August 25, 2015 That is NOT a PSA trigger set, it is made by ALG Defense! PSA is just one of the places that market it. Quote Link to comment Share on other sites More sharing options...

PSA is just one of the places that market it.You are correct.He's building a PSA rifle and needs the whole LPK, and since PSA has a version of their LPK packaged together with the AGL trigger... I just went that way with it.The advanced combat trigger is of course available from AGL Defense for $66, and the PSA ACT LPK is $99, so... take your pick.Thanks for the clarification 392. ;-) Edited August 25, 2015 by GreyGoose Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 25, 2015 Report Share Posted August 25, 2015 (edited) ^^^ Thanks for that clarification, on why you called it that - That would make sense for the OP, considering what he needs to get rolling. We're well aware of the two trigger offerings from ALG D, as well as the Spikes Nib trigger. Shiit, I had a Spike's Nib trigger in mid-2010, and 3 or 4 ACT setups in different rifles. The ACT is superior to the Spikes NiB. Edited August 25, 2015 by 98Z5V Quote Link to comment Share on other sites More sharing options...

The ACT is superior to the Spikes NiB.The ACT LPK is on my wish list! I recieved an answer from PSA regarding the compatiblity of a Rainier bcg and their receiver and I quote " As long as that barrel is a DPMS style barrel, you should be okay. We can only guarantee fit and function with other PSA products so at this time, I cannot guarantee another company's BCG with our .308 products. The receiver we have is based off a DPMS lower profile so I am not certain that a high profile handguard would work."! So if my reciever measures 3/16" but their recievers are low profile..............who's right? Quote Link to comment Share on other sites More sharing options...

dkreutsberg Posted August 25, 2015 Author Report Share Posted August 25, 2015 That diagram is where I got the 3/16"; however PSA uses a different way to determine high or low profile, I guess based on their affiliation with Odin Works kmod handguards. When ordering Odin handguards they ask you to use this diagram and according to it my receiver is a low profile.............go figure!

survivalshop Posted August 25, 2015 Report Share Posted August 25, 2015 I think we have seen problems with the Odin hand guard fitment before . The adaptor was not right , the poster had to contact Odin to get it right . Those directions talking about Armalite AR 10 rifles or PA 10"s ? Are you going to use Odin Hand Guard ? If so go with their directions . If you plan on a DPMS type Hand Guard go with the Troy measurements . Quote Link to comment Share on other sites More sharing options...

It should cut down on the odds on getting it wrong, somewhat. I understand that Midwest Industries which psa offered on their built rifles goes along with troy which means my reciever is now back to a high profile, both manufactures have some nice looking products so I guess it will come down to who has it in stock when I'm ready to order.Thanks Quote Link to comment Share on other sites More sharing options...

I am currently building a Gen II PSA PA 10 and I followed the guide line about the tang thickness and ordered a high mount DPMS rail form Midwest Industries. It sits a bit high, approximately 1/16" by eye. Although the tang is thicker the proper profile height for the rail is a DPMS low profile.
