acgeorge Posted August 13, 2017 Report Posted August 13, 2017 My DPMS upper has the forward assist, however, most of the bolt carriers I see for sale don't have the forward assist serrations. Can I use a bolt carrier without serrations? Are the carriers I see from aftermarket manufacturers with serrations compatible?
jtallen83 Posted August 13, 2017 Report Posted August 13, 2017 Most forward assists in the 308AR's will engage on the shoulder of the carrier but your mileage may vary. There are no hard and fast standards for this platform, I bought a FA that claimed to be specific for 308 AR's and it locked up the carrier without me touching it. You should be able to use a carrier with or without serrations as long as it is DPMS compatible.
StainTrain Posted October 4, 2017 Report Posted October 4, 2017 Exactly what he said. Some will engage, some won't. I like it for decoration on my DPMS, but when something needs to be forwardly assisted....my thumb gets the job.
survivalshop Posted October 4, 2017 Report Posted October 4, 2017 If you look at the upper part to the Ejection port ( DPMS LR 308 ), you can see the contact of the FA on the BC . Contact is here on the BCG Comparison to an M16 BCG There is a Manufacturer which made or makes a Upper Receiver & Bolt Carrier, that works just like the AR 15 family .
