Nice Gas Block
by Jason -
Just got done installing on a stainless M4 profile barrel. The gas block slid on perfect and looks good. The set screw spacing is .45 for those that dimple their barrels. I also like the way Expo packages their items. Happy with price and quality of product.
wish all companies would use PARMS C/service’s policies and altitude in solving problems. I will purchase items FIRST from PARMS
Expo Arms Value priced, Excellent Quality

Comes nicely packaged. Excellent fit and finish, no machine marks and fit on barrel perfectly. Way better than the price would suggest.
Excellent customer service after part issue
I had an issue with the set screws not tightening all the way. The fit on the barrel was fine, but the set screws would not go past a certain point. I used the chat function on the website and they sent me a new one that day. I was also contacted by customer service to verify i was happy with the service i received. This is probably the best customer service i have had. Very happy!
Perhaps a dud

Fit was too tight but after polishing it with fine grit sandpaper and steel wool, it fit. That’s a simple fix however, the main issue was the screws. They would strike sparks as you tighten them, they shed some metal shavings from the threads, and eventually broke an Allen key while trying to get the screws to engage with the barrel and it still would not hold onto my ballistics advantage govt profile barrel. No matter how hard I try to get them to tighten they would not stay in place.
<br>I ended up going to a local shop to pick up a different gas block.
Good Budget Block

Installed without issue. My gas tube does rattle in it, not sure if that is the tube being under sized or the block being over sized. Either way, no cycling issues.
Quality with a reasonable price!

Item is perfect for my change over to a low profile on my PSA A2 front sight/gas block. And the price is great. Ordered and in 2 days the parts were at my front door!
Quality plus price

Great Customer service with a problem gas block.

I purchased this gas block and it was a little snug going on to my barrel. I tapped it a little with a piece of 3/4" PVC and plastic mallet but it would not advance onto the barrel any more that it had and it was now stuck. I cut it off and left a 1 star review. PA Customer Service contacted me and we talked about the problem. My barrel is .75". To make a bad experience great, PA offered to reimburse me even though I had not intended to ask. Great customer service. Bottom line, if the gas block does not slide on fairly easy with the set screws removed, stop and check things out before resorting to force.
