what receiver set?

308lrnewb · June 28, 2016

I have been looking around some. Seen mega, rainier, a few others. which set do you all like?

How are those falkor defense receiver sets? That one looks good to me.

Which ones to avoid?

I took to thinking about what someone said in my novice thread about using a different receiver set. Saw another person mention falkor. Looked into that one. I like it more than some of the others.

All inputs and experiences would be great. Thank you.

Oh, I want to avoid poorly cut lowers. Out of location buffer detente bores, bad consistency and alignments. Prefer more tight fitting upper/lower mating. Intending to stick with matching sets.

Just get a matching set ! Stick with one brand. Avoid getting an 80% receiver and stay away from the word "Back-Order" !!!!!!!! And be patient the 4473 form may not be instant. Lol ,not funny.

What you listed are all good, matrix was one that was popular around here and also Areo.

stay away from places like blackthorn and some would say CMMG also. I've always thought you get what you pay for.

So, the falkor would be good to go? Proper and quality measurements, no issues with fitting? No known issues to be made aware of?

I know it looks a bit.. ugly, but I almost like it. In a strange way. Plus, the mirrored ambidextrous controls seems nice.

What is the word about their bolt carrier group, vs the rubber city and JP high pressure offerings?

If money wasn't a concern, I'd probably rebuild all my guns on mega sets. So nice.

Why on Mega? I heard they are very tight fitting. Which, I suppose is a good thing. Any other reason? Also, what is that weird set screw they advertise as being a selling point. About tolerance between the upper and lower.

What set are you currently using?

Im with Blue...get a matched set of upper/lower...or if you got the dough ray me get a monolithic.... ive got a couple of monolithics and some regular matched sets...quality all the way ...finish fit and ease of assembly Wash

I have a mega 556 set. My current 308 is matrix and I've had Fulton and DPMS. the set screw allows you to fine tune how tight you want the receivers. You can set it rock solid at the expense of having the takedown pin really tight, or decrease tension from there. Its a detent ball on a spring inside the lower that applies pressure to the bottom of the takedown lug. I wouldn't consider it a major selling point, but nice for people like me who hate any wiggle in a receiver set. The machining is gorgeous, and I think they are attractive. I like the way the shell deflector looks. I like the way they did the ambi bolt release. Very natural and comfortable.

I have an Aero M5 set that (while not quite as nice as some of those billet sets) is really very nice, and pretty cost effective too. I haven't had any issues with it, it looks and performs great. I will say that if I buy another set for a build in the future it will most likely be a Mega. My boss just ordered a few that he wants me to build for him and I really like that they come with a charging handle, dust cover door, and the takedown pins, all that is needed to finish the receivers is a regular AR15 LPK. I also like that they have no forward assist either...it's not really necessary for 308's IMO. The best price I've found on the Mega's was $510 (for the non-ambi set) at JSE Surplus.

I will say I like my matrix as well. Its almost as pretty as the mega, but lacks the ambi bolt release. Also very affordable. In case you don't know, these are the same receivers ruger uses on their 762 rifle. We have a member who is a dealer and has taken care of us in the past. My biggest recommendation if you went that route is to BUY THE MATRIX LPK. it has proprietary stuff.

Matrix gets a vote from me as well. Great price for a billet set and great customer service from Chris. Mine was a blem set but I can't see a blem. Upper/lower fit couldn't have been tighter and they have a detent under the rear pin to take up any slop should it ever be needed.

washguy · June 28, 2016

Jt. Thats good lookin...you have to use their lpk right? Wash

jtallen83 · June 28, 2016

I did use their lpk. Some have made it happen without but sounds like pins are not standard and the bolt catch is different, seems like everyone was filing on an AR-10 B model catch to make one work. For the money I decided to go with their kit, just used a different trigger and grip. 98 pieced his together with stuff he had, I had an extra pivot pin in my kit which just happen to be the one he didn't have in his bin.

392heminut · June 28, 2016

I used the AR-10A bolt catch for both of my Matrix receivers and they worked fine with no filing. I have no idea what the difference is between the A and B catches but I read somewhere (maybe Chris's website?) that the AR-10A catches work just fine. Seems to be the case with mine.

392heminut · June 28, 2016

Just remembered that Chris actually told me in an email to use the AR-10A bolt catch.

308lrnewb · June 28, 2016

Matrix and Mega seem to have the most consistent reviews. What about the raniers ultra match? No one seems to be on board for the falkor. Is this because falkor is out there on the fringe of the billet receivers?

Seems like Mega is the number one pick. I did look at their megalithic upper, it is nice. Was originally what I was planning to use. Those matrix do look decent. Also, I agree - forward assist is pretty much unneeded. Just one of those things.

Keep the receiver inputs coming! Thank you everyone.

blue109 · June 28, 2016

I'm sure rainier is nice, but pricy if I remember. Don't know anyone using one.

308lrnewb · June 29, 2016

hmm, ok. anyone here using that falkor mirrored ambi? Trying to decide what set to dump my bucks into, because I only want to do this once. Really want to drum up a BUNCH of responses full of reviews. All that 'good, bad and ugly' type of stuff. Please, pull no punches. I like how the matrix seems pretty sturdy. Decent looking and I like the tension detente.

Rainier ultra match 308 currently rings $550 from their webpage. Seems about in line with all the rest, really. They claim it is extremely parallel.

Mega had my interest to begin with. I may just opt for one of their monolithic types.. *shrug* What is a standard price for a blemished matrix set?

shepp · June 29, 2016

Like I said all those companies are very reputable, do one have somthing different here and give us a review?

washguy · June 29, 2016

"Mega had my interest to begin with. I may just opt for one of their monolithic types.. *shrug* What is a standard price for a blemished matrix set? "

Lrn.....man you are getting skitzed out...its making me sea sick..going from Mega monolithic back and forth to a blem Matrix.... and a Fokker thrown in

308lrnewb · June 29, 2016

Thank you for the support, shepp! Way to shove me more into that fire.. Like I needed any more prodding. I am unsure if it has any way to 'tighten' the lockup of that take down pin, like the matrix and mega do however.

I really think I want the falkor.. Just - I like money as much as toys. =C

hey YOU asked our opinion

308lrnewb · June 29, 2016

:thumbup:

True! Seems like the matrix blemish set is almost the way to go. Heck, two cans of cerakote rattle paint.. *whistle*

Lemme wait a few more days, then find out more from Falkor about this bad thing. :embarrassed:

blue109 · June 29, 2016

My matrix blem had no noticable blem. I think the "blem" was that it was a little tight around the front pivot lug. When I first got it I had to give it a good tap to get it apart. It has worn some of the anno away from there and is about normal now.

Again, just remember to get the matrix parts kit with it. Save some headache. If you dig around the matrix forum in here you will see every possible problem and solution. Bunch of us bought them at the same time so it was like a long distance build party.

308lrnewb · June 29, 2016

Will keep in mind blue109. If I opt to not go Falkor.. May go matrix. Seems like the best bang for buck if not wanting to get all that 'wild' with the non-milspec billet lower. That tension detente seems nice. I know some people will slip thin pieces of soft plastic in their receiver to perform the same task.

I bet it was exciting - that telephone build party. The rush, seeing who gets finished first and comparing results after everyone has a few range sessions. C= well, I am glad to see everyone here is so darn nice. Thank you, everyone - for the warm, almost smooshy feeling of less than razor's edge responses. Some places can be pretty hard to clique in. You all have been pretty alright!! Who cares what them poodle shooter .22 crowdspeople are saying... :lmao:
